- Steam Radiator Not Working? There are a number of reasons a steam radiator may not be working. Could be a problem with the radiator itself or it could be a system fault. In this video, I'll cover some common problems I find at the radiator.
From tackling a faulty air valve, packing a leaking valve stem nut, when or when not to turn off a steam radiator. If you're a D.Y.I guy or gal considering replacing a faulty steam valve I have a link to a video I did which will show you step by step instructions on how to do it safely.
Steam Radiator Valve Not Working? Hopefully, this video will clear up some of your questions and have your steam radiator up and running without too much pain!
Regards & Happy Plumbing,
Bob

Bob, I wanted to thank you for turning me on to the Lost Art of steam Heating ,by Dan Holohan . I have been watching Dan's videos and couldn't be more impressed, I cannot imagine there is a person more knowledgeable about the subject ( a true historian). I am currently watching one of his lectures on the 1918 Spanish influenza and why the radiators were oversized and the windows open from 1918 to 1920 ( it kind of puts the covid-19 pandemic in perspective and he made this lecture in 2015).
Bob, thanks again and I can't wait to start diving into Dan's book and more of his lectures online.
He is a very special guy, I attended almost all of his live lectures and was mesmerized by how he told a story. A truly gifted person. Regards, Bob.
Is there any way you can help me with my system
Lost art? Tons of houses and apartments are heated this way, including mine which is heated with hot water and has 1900s brass rads

This should be mandatory viewing for all NYC apartment owners, tenants.... with a test at the end. Nice work.
Agreed. I’m in a condo and my upstairs neighbor, a wonderful gentleman, keeps flooding my ceiling under his bedroom. It has ruined my ceiling!!! This information should be disseminated to all tenants and especially to new owners.
Hi Bob, we have the proverbial 100 year house with all this old stuff! I would like to highlight that the Radiator Isolation Valve has a union as part of the arrangement. Unions are metal to metal sealing surface so while you may think the “pipe dope” is sealing the union, you would have the same result with using a good anti-seize paste. The Union basically just needs some lubrication to overcome the thread friction which is likely due to some misalignment between the radiator and piping. Finally, Teflon tape on the threads on this Union, is likely used because of not understanding how this fitting is designed to seal. Teflon happens to work, not because it is sealing the pressure inside fitting but because it reduces the thread friction, acting as lubrication again, which allows for further engagement of the threaded collar; imparting a higher compression force on the seating area. If the seating surface is scratch significantly, e.g. while positioning the radiator, it may leak no matter how tight you make it. It would need to be resurfaced by lapping or replaced. In summary, all unions are a metal to metal joint. Signed Steam Ship Engineer.
Great video with specific focus on steam cast iron radiators and peripherals. Very comprehensive and well explained. Excellent camera shots too. I’d be interested in vids to learn more about automatic water feeders on steam boilers, troubleshooting and recommended maintenance.
Thanks Bob, You're a blessing to humanity. Seriously, I wish all of us would share our expertise with others!
I'm so glad that I watched all of your videos and changed out my 25 year old steam radiator valve. Best advice ever!
Thanks for this Bob. Appreciate that the video isn't just a demo of how to fix one specific issue, but is a tutorial of the various issues that a homeowner may encounter with steam radiators.
Thanks a million Bob - this is the first time I am moved to make a comment on a video - a true blessing to have the opportunity to listen and see your video - a superb teacher - many blessings to you - thanks again
You are very welcome! Bob
I had to teach myself about my steam system as there arefew residential steam systems left where I live. Used Dan Holahan and his folks on The Wall. Techs here know little about it. Wish we had someone with your knowledge. Thanks. Nothing better than steam heat and cast rads.
Bob, this is an AWESOME video. Super informative, and I love the way you went through the explanation in such hands on detail. Thank you for making this and sharing.
Glad it was helpful!
Home inspector out of Cincinnati here and I find your videos extremely informative. Thank you for sharing, Bob!
Thank you Luke, much appreciated! Bob.
Thank you for your knowledge. My parents brought a craftsman bungalow in northern Ohio 3 years ago, built in 1927. Still has the original steam radiators. When I was over to visit for the holidays I really liked the constant and even heat. Lol highly unlikely any heating system manufacturer today will still be around in the next 90 years.
Thanks for sharing!
Thank you for the education. Who would have thought there are much to learn on a simple steam radiator.
lots of common sense tips for managing your heating system. a must watch for homeowners with steam radiators.
im gonna blow my mechanic's mind with what i learned, thanks bob
The radiator has just always been there. Taken for granted, neglected. Now I have some basic understanding of why and how. Not the boiler all the time. Much thanks. 🙏🏻✌🏻
Great video as always. Your words on the thermostat resonated. I say that because there has been so much focus on energy efficiency by keeping the thermostat at the bare minimum so you don't waste energy. However, steam is a different beast. In our setup, we have a single pipe system on the first floor on one thermostat, and the upstairs is hot water baseboard connected to the same steam boiler on another thermostat. On the first floor, the small radiators don't heat up. All the radiators have vari-valve vents, but it was the thermostat being too low. Problem solved!
Excellent video! I learned more about our steam radiators from your video than I found in any other videos and from our HVAC company! Thank you!
Glad it helped!
Great video and information! I share your videos on valve removal with all my coworkers !
A great and very informative video, you completely explained so many radiator issues.
Thanks 👍
Just found this and joined. Better late than never. Small cape built in 1942 steam heat. Replaced boiler from oil fired to gas. Removing all radiaters to clean, paint and make repairs. Very well explained. Time and efgort appreciated
Thank You! Regards, Bob.
Great video. I can’t recommend this to anyone who has steam radiator heat. The video is clear, concise, logical, comprehensive….Great!
Much appreciated!
@@BobsPlumbingVideos can you use two air vents on a steam rad???
Thanks so much! Recently bought a house built in 1929. radiators sound like Mayberry band! radiators leak at values. Some have no turn off valves. So very helpful! Virginia.
Feels like I went to school on radiators just from this video..!!💪💪💪🔥
Explained perfectly! I usually heat up spud or radiator with special notched tool to work it out because spuds usually are fused by the years.
Bob, your video on radiator valve repair was VERY informative. Thank you
Very welcome! Thank You!
the most relaxing thing I've seen all day
Thank you for this! I recently purchased an old victorian out here in PA and was clueless. Never was introduced to steam heat until now. Appreciate this video
Glad I could help! Bob
Thanks, I fixed the radiator following your advice.
Best info about steam radiators on the internet!
excellent and informative video thank you this answers 2 of my big questions that no one would answer
THANK YOU!! Just bought a 100 yr ok’d duplex by Detroit. River - I’ve never had a radiator - and literally having all of these issues on various radiators !!! Thank you !! I’m going to check out the lost art info as well !!
Glad I could help!
Well once again you are outstanding. I will call you from now on "Bob the Great" !!! He's the best. 😊
Top notch presentation great for new steam heat homeowners
Hey Bob! I'm gonna start scrolling the comments, but we ran into an issue last night. The radiator in our kitchen is getting warm at the top but cold at the bottom. We've only owned this house for 6 weeks so this is all new to us.
Where is the air valve located on that radiator? What floor is the the thermostat located? Many possibilities?
Very helpful video. You’re the man !! Thank you.
Just want to say thanks. I fixed the leak myself and saved $.
Great video Bob. I have a one pipe steam system and two things I do each year are to take off the pigtail and rinse it out. A lot of crud can get built up in the pigtail and could hinder the operation of the boiler. Also, I replaced my steel pigtail with a brass one, which wont rust over time. The other thing I do, is to put in boiler cleaner each year. I put a T on the nipple where the relief valve was, installed the relief valve on one end of the T and put a plug in the other end of the T. This allows me to put a hose into the boiler to put the boiler cleaner fluid in. I put a funnel on one end of the hose to make it easier pouring the fluid in.
Love it! Take care of a steam boiler & it will take care of you! Regards, Bob.
Thanks for the tip - do you happen to know if there is a video about your suggestion it sounds really useful
@@dulcebodden5241 I have not found one. Take a look at where the relief valve comes out of the boiler and there will be typically a 2' or 3' black pipe coming off of that. This is what I reconfigured by putting the T fitting into the boiler, putting a plug on the other end of the T fitting and then putting the relief valve on the center part of the T. If I could post a picture of what I did on CZcams I would be happy to do so, but dont believe I can
You are rock Bob! Thanks for making the vedio.
Thank you very much for this video. It's helpful.
Thank you for thos video. As a woman trying to DYI I enjoyed and learned so much
You are so welcome! Thank for your visit, Bob.
I was able to get the radiator working by clearing the vent hole with a paper clip. Great video!
Excellent!
Wow.. Fantastic instruction and diagnosis
Thank You !
Thanks Bob, I definitely thought that the valve was used to control the temperature. I just opened all my radiators up
Excellent!
@@BobsPlumbingVideos I just bought the house and now a plethora of leaks and random sounds have evolved from all my old radiators. I dunno whether to laugh or cry. 🥲
You are the man Bob!
I try my best!! Thanks for the visit, Bob.
Your the man!! Thank you.
Thanks for sharing. We replaced our steam boiler in 2018 and ever since had trouble with the radiators and heating system in our 5 unit bldg. They also replaced all the air vents in an attempted to balance the system in 2018. We had substantially more banging. In 2018 -19 many of the new air vents were spurting water. We checked all the radiators and pitched ones that were needed. Water stopped spurting and not as much banging. I kept telling them ( the guys who installed the boiler) I would hear running water in one of our large radiators. They had very little ideas of what to do. Between 2018 the banging got worse and our radiators this year were not heating up. We pitched it more. Have minor banging compared to what we originally started with. Previous winters the radiators at least heated up, not true this year. Replaced the air vents. Heat is now getting through the rungs but we are now getting a lot of water spurting on the vents replaced. One vent clogged again ( I think because of all the water) so I changed that one again ( the radiator at least gets hot now) . One vent just has a very loud hissing noise. What else do we do????? The guys who installed the boiler have absolutely no answers or help. I honestly think the took a job that was beyond them, so any suggestions we would appreciate!
Second issue- in our basement apartment the radiators are on the ceiling. The air vents have always been tricky because they hit the ceiling. Would one of the straight valves you mentioned in the video be appropriate there. When I mentioned this to my husband he said those straight valves are not used for that.
Go to www.heatinghelp.com and post your question. This site was created by Dan Holohan the guy I learned from who is an industry expert on the subject of steam heating. Did they size the replacement boiler correctly by performing a heat loss calculation for the building? Or just match the existing one or perhaps go one size bigger? BIG MISTAKE! All things equal, replacing the boiler won't correct system issues that were present previous to the new boiler. I use the straight valves if I have no other choice, but they are an option.
I moved in with my elderly aunt to help care for my uncle. My upstairs bedroom radiator is cold. Or at least the giant iron box covering it is cold. I watched a bunch of CZcams videos and eventually figured out there is a Gorton vapor equalizing valve on the front middle. The service valve is in the fully open position I can hear steam in the walls when the boiler is on.
After watching your video I now have an understanding of the system. I know there is nothing for me to do here. Will check re thermostat and see if it shuts off before upstairs can heat. It’s important to know when to stop with DIY Stuff.
I am curious about how things work. You more than satisfied my curiosity about radiators.
I hope there is a video on boiler maintenance!
Excellent video. Thank you !
Glad it helped!
Always nice to change the valve
Thank you Bob!
Great video
Very informative
Thank you!!!!
Happy to help! Thanks for checking out the video! Bob
The air valve in the room with thermostat should be a slow air release. Gordon valves are numbered from 1 to 6 depending on the rate of air release. See their catalog for recommendations .
Thanks 🙏🏻 you save me money 💰 GOD BLESS YOU PAL
My pleasure Edward! Thanks for watching! Bob
Bob thank you for sharing your expertise, the question I have is how do you deal with a leaky Governale steam convector, they leak usually from the end caps
OUTSTANDING!
Excellent teacher
Many many thanks
super helpful. you taught me a lot. this was perfect, im pretty handy and this got me up to speed really quick. do you have another video on the main boiler and how that operates the system as well?
Definitely will make that happen!
Thank you so much! New subscriber
Thanks for subbing! Much appreciated, thank you. Bob.
Nice work!!!👍👍👍👍👍
Thanks for the visit
Very Good info.
Thanks for watching!
Great video manm im having issues with one of my appartments
Sorry to hear that
so much knowledge
What a great video! Thank you so much!! I grew up in NYC and I would have steam or hot water heat any day over forced air heat. You're so right pipe dope any day over Teflon tape.
P.S. That is the Cutest Small Pipe Wrench I have ever seen!😀
Is it a Rigid? I may have to get one.. seriously.
My most favorite wrench! Thank You, Bob.
Hi Bob, just finished watching one of your very informative video clips on those steam radiators. Very, very nice. Just ❤️ it. Will continue to look out for more like it. Anyhow ,question, do you have to drain the water out the hot water radiator system to stop a leak coming from where the Air Purger connect to the expansion tank?
Unless you have an isolation valve before the expansion tank, YES you do!
Hey bob thanks for the video very helpful. Having problem with 2 radiators. When the steam starts to come up the radiator makes banging noise. Any suggestions.
Well done! (Subscribed)😀
Thank so much, alot of excellent information what about adjustable air valves are the able to throttle down the heat. I have the radiator in the room with the thermostat or should I shut down the radiator all together like you explained.
I would first try shutting off the radiator in that room and how it goes. That just my solve the issue, or you can check out this video for the thermostatic radiator valves. czcams.com/video/jWfr1LuvJRs/video.htmlsi=tT-Vvu3w_GM_seHb
When I ind uneven heating, I make sure first, the main vents are working, then install adjustable vents and slow down the venting in the room withthe thermostat if it shuts down too early, then speed up the venting in the ones that dont heat all the way across the radiator. It also sometimes requires cleaning the system of dirt from not cleaning the wet returns.
Great point!
Hey Bob do you have a recommendation of an expert on jersey I can hire?
I have referral in South Jersey. WaterWorks Plumbing 732-566-0105. Andrew Gurrera, tell him I referred you.
Thanks and bless you much
You are so welcome!
Thank you for the visit, it's much appreciated!
Bob. Wow, all excellent information. Turns out I’ve been doing it wrong for years and years. I would like to know now what happens when the water keeps spinning out of the valve on the side of the radiator and second what is up with those adjustable valves?
Several reasons why water would exit the air vent. Excessive pressure, backpitched pipes, a bad air valve (rare) should be checked out by a professional. Adjustable air valves could be a good solution in certain conditions, but I personally prefer matching the right valve for the radiator in question.
I usually use two pipe wrenches to avoid any unwanted stress leverage on old risers. Better safe than sorry. If it's a big radiator then the weight itself would prevent any movement. The majority of the time the shutoff valve to spud should come off with not too much effort, but anytime too much effort is needed then a little heat applied will do justice in not twisting unwanted things.
One of the guys that used to frequent the Dan Holohan site put in our two Steam Boilers..but no longer is doing private work.
Instead of the large Oil Fired Weil McLean 445 btu Boiler he put in two Smith Series 8 185 Btu Boilers that are Gas Fired (Carlin)
Those Boilers are also used for Oil ours are gas fired.
Our Boilers are at one end of the house and the rooms at the farther end which actually was an extension
just only gets somewhat warm when heat is blasting. That extension is over a crawl space accessible through a small window in basement.
The Steam pipes in that crawl space have been insulated. They put quite a few of those large Gorton Main Vents in the basement to help get heat there
..we used to have two he added another 6 or 8 of them. He even added an extra Vent on the two Radiators like yours has over there still very little.
We kind of keep heat moderate (64-67 degrees) as house is very large but made in 1874 with extensions on in 1929.
Maybe some sort of supplementary heat ? We had one of those Delonghi Oil things..the best one..and it popped one day and oil soaked an
Oriental Rug we had. Those things are such garbage.
Maybe one of those Mitsubishi split AC/Heat units to supplement and control by its own thermostat?
Great video! I have a 1 pipe steam system and one radiator is spitting water out of the air valve, which I just recently changed. I also changed the shutoff valve on it and drained it. When I pitched it, I definitely went overboard, could that be a reason for guys issue?
I also have another radiator that I over pitched, it's only getting hot on the top side, but the bottom is luke warm. Recently replaced the vent because it was also spewing out water. I also drained it.
Could over pitching be causing these issues?
Thanks for the awesome video! The only thing I'd like to hear more about is the air valves and the different types. In my new (old) home I have 3 different types of valves and it's tough to figure out what setting they need to be on. Some have a dial that spin endlessly, and some have a numbered dial. Should they be open or closed? And how does that affect how hot the radiator gets?
Thanks again!
I have the same question. I hope Bob answers this question because it is confusing with so many types of air valves out there
Bob, Have you discussed two-pipe steam? The pluses and minus? Finding defective traps? Thanks, Ed. W.
I have not Ed, I don’t work with many two pipe systems. I do 90% residential one to six family homes and an occasional apartment complex maybe 20/30 units. A close friend and licensed plumber services a lot of the local schools and churches and works on two pipe systems all the time. Steam traps, condensate pumps etc.
Bob, love your videos! I need help picking steam radiator paint . Already have the Rustoleum high heat but can’t reach the inside. Which one to buy please? And where? Thanks 🙏🏼
Ideally you would use aluminium paint and spray it on. If you're going to use a custom color, use oil paint and preferably spray it on.
Bob - another great video. A relative of mine had a 2 vent (top & middle) configuration like in your video. Both vents were leaking. I replaced the middle vent and simply plugged the upper hole of the radiator with a 1/8” NPT plug. Everything is working fine. My question- why would any radiator need 2 vents? I would think that one vent with the properly sized vent hole would be adequate. Did I do this correctly or should I remove the upper plug & install a nipple with a vent as you demonstrated?
No need for two vents, I generally will use the lower of the two, but either will work!
I have old steam radiators and I noticed that there is one pin hole in the top large cast iron nut and sometimes water spouts out of it. The ones on the main level don't seem to have a steam bell, but these tiny brass bleeder valves that I don't know how it works that seem to be newer added pieces. The one in my room upstairs does have a bell but it does the same thing, there's a pin hole in the top large cast iron nut (with the brand stamp on it and also says No. 2 In Airid Vacuum Air Valve, American Raidiator Company (edit- apparently these are invisible air vents?) The repair man said that these singular pin holes should not be there and the bell upstairs doesn't seem to work because the steam is constantly spitting straight steam from this pin hole in the nut making the room unbearably hot. At least 2 or three times over the season the whole system spews water out of these pin holes that apparently shouldn't be there. One of the radiators in a different upstairs bedroom only partially works, no leaks in that room but it the valve doesn't seem to work. I'm having a very hard time finding a repair professional to explain to me what's going on or even wanting to touch them or explain how the American Raidiators I have work. I've had three men look at it, and say well that looks just wrong, but no fixes. They just tell me to monitor the water intake manually by monitoring the glass valve on the system in the basement. But steam is still spewing out these singular pin holes. The system pressure seems fine most of the time. Do I just have an odd models and the hole is actually supposed to be there and someone came along and added bells and valves that didnt need to be there, or something quit and they added these things? Or do I just need to replace the bells and cover the holes? Please help!
Send me some photos so I have a good idea of what you have. Send them to info@robertsessaplumbing.com.
Hey bob great video, i have both radiator heat and hydronic heating too.. you got any videos on how to purge air out of a hot water boiler?
Thanks for asking, I'll have to put one together!
Usually there is a small purge valve on each radiator with a hex key. Start on the rad farthest from the boiler and work backwards when the heat is on. It will eject air. When it starts spitting water, turn the key off
Hi Bob, I have a recessed cast iron 6 foot wide steam radiator on a single pipe steam heating system. After a few days, of normal heating operation, there seems to be a lot of water stuck in the radiator. I have to use a small hand lotion pump to siphon the excess water out of there radiator for it to function properly again. To do this, I take off the vent valve and stick a tube inside. I tried tilting the radiator more to try to ensure that it drains back but since it is a recessed radiator, there isn't much higher I can pitch it. All my other radiators are working fine. Also, I'm currently using a hoffman special 1a vent. I have also used a Gorton C vent, varivalve quick vent, and the hoffman 40 vent. Any suggestions?
Thanks
Hi Bob. Thanks for the great informative videos. With respect to the radiators not fully heating on the second floor I am wondering if, rather than moving the thermostat, one can just put in vent valves that vent faster on the second floor and slower ones in the room where the thermostat is mounted? If, as Dan Holohan says, “steam will take the path of least resistance” it would seem to be an intuitive solution. The 2nd floor would get the lions share of the steam until their vents shut down then the lower floor would get their share until the call for heat is satisfied. Years ago I did replace a small radiator in a second floor bathroom with cast iron baseboard because the radiator was keeping a doorway to the 3rd floor partially blocked. We use the third floor only for storage and I had to take the door off every time I needed to move something big up or down. After installing the baseboard I initially used the vent valve from the old radiator. This valve didn't allow the baseboard to heat all the way across under any circumstance. I replaced it with a vari-valve and presto, it heats all the away across under almost all conditions.
You absolutely could go that route by using specific valves based on the distance from the boiler. Gorton valves have a chart available on their website. Also I've had much luck turning off the radiator in the room where the thermostat is located. Especially if it's an oversized unit for that room.
Thank you for your videos they have helped me understand a lot more about steam than I knew. I have one radiator upstairs that doesn't get hot I can feel the heat go to the service valve but it stops there I do hear and feel the steam coming from the air valve but no heat. Any ideas. Thank you!
Many possibilities, bui one of the most common is thermostat location. I like to have it located on an upper floor in a room that's not to warm. Typically when I get the "radiator won't get hot all the way" complaint, I find that the system has shut because the thermostat has been satisfied and the system has shut off. Many, many more reasons this could happen, but I would start here. Is the room where the thermostat is located getting to warm to fast?
@@BobsPlumbingVideos Thank you for your extremely fast response! I moved the thermostat upstairs last night and the rest of the house is very warm but the radiator is still not getting warm except for the shutoff valve I and going to try to repitch it today to see if that helps as it has a gurgle and a slight hissing sound. The radiator is the only one in the house that has a 1" copper pipe running to it the rest have old black steel (I think) going to them. No matter what I really appreciate your response and videos, they are a huge help to a lot of people!
Nice video very informative. I have a Question: As a plumber's apprentice and a beginner, which book do you think is better to start with "the lost art of steam heating" or "we got steam heat a homeowner's guide" which is also written by Dan holohan?
Lost Art first followed by We Got Steam Heat. Regards, Bob.
Hi Bob, thanks a million for the detail explaining cast iron radiator , I am experiencing different issues. My cast iron steam radiator sounds like water running when the heat is on ?
May be a back pitched line under the floor, water in the radiator, you may want to get it checked out by a heating pro.
Decades ago I was living on the first floor of a 2 family house and the heat was a good but there were large swings in the temperature in the winter. The thermostat was on the livingroom on a short wall between two doorways and the console TV was placed there. The set gave off a little bit of heat but not a lot.
One day i was looking at the thermostat wondering why it read 74 and the room felt a lot cooler. As i was looking things over I realized that wall was very warm, after looking downstairs i found a steam pipe going up that wall to the second floor and that was warming that wall up and turning off the boiler. I moved the thermostat around the corner to a wall that had no pipes in it and everything was happy.
Happens more often than people think.....👍. Nice Job!
Hey bob I learn a lot from your videos. I live in New Jersey in Hudson county was wondering if you have a company that deals with steam boiler or have a number thank you
Go to heatinghelp.com, click on "The Wall" enter your location to locate a trade professional in your area. This site was created By Dan Holohan the "Godfather" of steam heat. I credit him for my education on steam heating, he wrote the bible on the subject "The Lost Art Of Steam Heat" available here - amzn.to/3DDFAEk
Nice video, thank you. What is that little pipe wrench you used on the radiator valve nut, is it a 6-inch, maybe even a 4-inch? Could you perhaps post a link to one? Thank you again in advance.
Here you go - amzn.to/33gLlek Thanks for checking out the video. Bob
Hi Bob, great stuff, learning a lot, especially since I'm a new residential steam boiler owner in a 100 year old upper peninsula Michigan home.
Question - a few of my radiators will only heat (about halfway across) only of i totally remove the air vent. The service valve is open fully. I guess a bad service valve being stuck closed maybe. Whatca think?
Mark
A. is the thermostat shutting off before they have a chance to warm up? (thermostat location) B. Where is the air valve located? Check this video out. czcams.com/video/65zaJ1Bbf-I/video.html
Hey Bob, thanks for the video. I cant for the life of me find the bleed value on my very old radiator. Seeing alot of videos that show an obvious hole on one side towards the top and not seeing that on mine. Just to clarify, that is not the same as the hole for the air value correct? Meaning I should NOT be putting a radiator key in that hole?
Wondering if I just need a new valve, no parts of the radiator are warm, though the pipe leading to it gets hot. All other radiators in the building seem to be working fine. Thanks for your help!
Steam System?
Great Video,,, Do I have to buy different air valves for the 1st floor and 2nd Floor?
This is a general guide - www.gorton-valves.com/products
Mr. Sessa, is it possible for risers to corrode or plug up? I removed the Hoffman bottle valve and when a system has positive pressure I would expect to hear air/ cool Steam to be flowing out of the 1/8 inch whole and yet I don't. Does the cooling and condensing of the steam neutralize the pressure before it gets to the end of the radiator? Is it possible risers for to plug up? Also curious on the return drip leg do you flush those out? And if so how often?
Just speaking generally about residential steam systems (god knows there are a million variations / causes) I've come across back pitched horizontal branch lines which fill up with condensate after a few heating cycles. The result being the steam either pushes water up the riser or in extreme cases prevents the steam from ever making its way to the riser. Once the radiator is full of steam the condensate will drop to the bottom and work it's way back to the the boiler thru properly pitched piping. Does not affect the pressure.
THanks for the information! One question bob, one of the downstair radiator only half of it gets warm. Everything else works fine and i can't figure it out. thank you!
Thermostat location and how warm that room gets!
Firstly I want to thank you for all the good info you shared in the video. The best yet. I have a problem that you haven’t touched and wanted to see if you were able to help. My problem is actually the opposite of what you mentioned and that is that my upstairs gets very hot and my downstairs is very cold. The thermostat in downstairs and it doesn’t reach the set temperature in the winter. The radiators only partially get hot. I can even remove the valves completely and nothing comes out. No steam no sound no air. What do you think I should do?
Undersized boiler ? , undersized radiators 1st floor? , You need to have someone come in and do a step by step diagnosis. Can't solve this one without being there!
Thanks for replying. Keep up the great videos.
Bob, thanks for making such a informative video. Quick question ... Since I have a house that was built in the 40s, that's how old my 1 pipe steam system in my house.
On the second floors, I have 2 radiators. One gets so so warm, the other is ice cold. I suspect that the valve is at fault. It is a Hoffman. I took it off, and the tongue was actually corroded and are a angle, versus being horizontal, up and down.
Does it sound like the valve is at fault. Yes, I checked the main turn off valve, which was wide open. We never close the main valves. Oh, the air valve is located on the bottom of the radiator and is the only valve.
Appreciate your thoughts here on Long Island! Rick
On the surface, it's sounds like a bad air valve. Check that the thermostat is not shutting off the boiler before that radiator has a chance to heat up. You may also consider using a gorton #C or #D air valve to vent the air quicker than that hoffman #40 (which by the way is a great valve)

Thanks so much for your advice and suggestions. Just back from home depot .... They didn't have the ingress you suggested, so I went with a #40. Already installed it after draining the excess water and checking for level. Fired up the burner ... Made sure the valve is open again. Still having problems with getting heat up. Just cranked the thermostat up to 75 ... Now it's working. Hoping that it will continue to do so.
Thanks so much again!
Excellent video Bob, What are your thoughts on Vari valves? I bought 10 for ,my home and they seem ok but i suspect I need to fine tune a few as I get gurgling from 2 of them. I adjusted both that were gurgling and it seemed to stop for now but any ideas or suggestions you have are appreciated.
Haven’t used them of late, I remember they didn’t tolerate water very well. Always ended up changing them out.
@@BobsPlumbingVideos Changing them out with what, there are not many choices that are adjustable.
Bob, I have so many questions for you....I hope you don't mind.
Do you recommend putting a reflective metail (foil, sheet metal, etc) behind each free standing radiator so that it reflects the heat back into the room as opposed to losing some heat to an exterior wall?
You can get insulation board with foil on both sides to place behind the radiators. It certainly won't hurt!
Hey Bob, cast iron radiator single pipe do you have a degrees to set the level to help draining cold water condensation returning back down Thx!
I just use 1/4" wedges to prop up the cast iron radiators towards the shut-off valves. Maybe 1/2 a bubble on the torpedo level.
Bob thanks for the video. Do you have a video on how to clean and flush an old radiator that is not getting hot even with everything wide open?
I do not, what type of system steam or hot water?
It's a steam system with steam coming in from the valve and 1 vent on top on the other side. Thanks
