Love commercial over domestic vids every time.
Thanks
Keeping it real as always Mikey Pipes. I loved doing commercial work over the years. Installing heating systems in massive schools and buildings was fun to me. I miss it. I remember having a GC asking me why I was firing off all 4, 500,000 BTU boilers at the same time and if it was a good idea. I asked him if he knew if they were installed properly and if they would be running at the same time in normal use. He said he had no idea. I said that's why IM firing them off and not him. LOL Something about bringing systems like that, bringing heat to a building that never had it or hasn't had it in months is a cool feeling. Make the trades great as always Mikey Pipes.
Mike that was some good training, I feel like I should pay you
Donate
holy crap !! gigantic complicated units, that moved on up to the east side, to a deluxe apt in the sky. ! lol
ROTFL
Most impressive Mikey, commercial stuff is a whole lot more sophisticated than the run of the mill homeowner stuff. Keep up the good work. Yes, New York never sleeps - nor does Mikey Pipes
Just another thought Mikey Pipes your incoming gas pressure was approx 7.4" W.C. (run pressure) you have x2 water heaters (600 btuh total) as well as x2 boilers .. with what looks like 1 1/4" BMI a factor that seems to be missed (especially if the units are under firing) is to verify what kind of meter / regulator you have supplying that restaurant. I'm not all too familiar with commercial but in residential some regs (mini 260s or Itrons) can only supply approx 550-600 Btuhs. This building likely has a rotary meter and is either being fed in psi or inches but never a bad idea to verify
food for thought
Hey Mike, I actually passed by you that day in the sprinter on the onramp from forest hills to the grand central. I was like wait a minute, ive seen that guy before.
that was me! i probably have you on my video clips i didn't use
Good video Mike. Loved the end with the crazy motorcyclist.
Glad you enjoyed it
But when they start cooking and turning on the exhaust fans is it pulling air out of that room?
nice job , pretty involved.. your the MAN brother
Good job Mike, Klonopin is usually used for anxiety and stress, doesn't mean you have a problem, just means your business or customers put you through an unfair amount of stress.
Damnit those crazy customers.
Wonder if the guy who supposedly replaced those flame rods was the one who left it to the gas valve to support that whole length of 1 1/4" piping🙄. Nice fix!
Great video very informative
Glad you think so!
You can do it Mikey!!
A customer of mine has a version of these boilers running in their restaurant. The design of the condensate trap at the bottom of the exhaust connection has demanded regular attention. Flue corrosion means that the trap collects condensation, rust and dirt/corrosion particles and plugs the drain. The condensate connection at the beginning of the video you mentioned gave me serious flashbacks. AND YES, neutraliser needed for sure.
stay tuned for part 2
You’re the best on the internet
far from the best
one of your best, thanks!
Wow, thanks!
Mikey you’re exhausted…we all been there but with out the coffee and pastry 😂😂😂.
very educational video.
Thank you
Nice job Mike. I didn't think that you went into Manhattan.
Case by case only.
On these units the condensate traps get clogged and need cleaning fairly often.
Good lessons Doc
Tyvm
Hey Mikey, of Mikey Pipes Plumbing not easy being cheesy. I like your podcast/social media, looking thru some comments/reply?.I guess some of your customers, family and friends still checking in on you. A crust of bread and a corner to eat it in. A minute to smile and an hour to weep in. A pint of joy to impeccable troubles and never to laugh. Because the moans comes double, and that is life. Love you buddy, God bless you my brother in Christ.
Eating hazardous materials separates a good plumber from geniuses. 😂😂😂
The combustion chamber evidence of corrosion leads me to believe there is contaminated combustion. Other comment mentions grease from the vent hood. Typically seen in food service applications so makes the most sense. Dont rule out that at times the exhaust from this or other gas appiances could be the cause. All these are highly acidic which would also show the heavy signs of corrosion. I've also seen sewer vents located untder an intake which will produce the same result.
Verify that the differential set point is also not set at 4 degrees F or less. Better to keep these heaters from short cycling, default at 8F degrees is best practice.
These heaters are actually mfg in their Plant in beautiful Mcbee, SC. Like your vids
Love these units. Correct with the contamination. Never overlook it.
Great video ive worked on a lot of these I didn’t notice any expansion tanks Ive found that they don’t last very long with out them
You're the Best mikie pipes 🍾🍾🍷
far from the best
You are the master
realy enjoyed yhis
Thanks
That looks like a nightmare to work downtown. Was the combustion within specs? I would recommend changing the air intake location, if possible. Are they using any chemicals in the cooling tower that could react with the burners? Great Video, Mike. I had to laugh about the scooter driving during a winter storm. Thanks
I would definitely recommend supporting the gas pipe, so it doesn’t break a gas valve.
thanks mike journey man plumber in Iowa i have worked on commercial power vents before and got a sense they were just a high 90 percent furnace running in reverse the mesh is combining the fuel and air but its more like lantern and the bottom induction motor sucks the spent gases out is there a heat exchanger under the water heater?
Mikey! Love your videos man, I’ve learned a lot from you. Thanks for your high quality work out there.
What was the actual cause of them both failing? And what was up with those blocked vent failure codes? Were there any ignition failure codes?
Those igniters looked bad for sure. Flame rods definitely needed cleaning and/or replacement. Personally- I like to document flame signal before and after flame rod replacement to prove a flame loss/ignition failure. Not saying you did anything wrong but I think it’s good practice imo. If you ain’t testin ur guessin!
Inlet gas pressure looks good - no drop. Obviously the condensate needs fixing holy s#%t.
Definitely a weird one man.
Mikey, You'd need a smoke machine like they have for auto repair looking for leaks in evaporative fuel lines and intake.
38:20 Wating for the guy on the motorcycle to get his jacket caught in the tire and take a dump! 🍿🍿 😜
You too?
NYC work big money
yup. damn commercial parking on the street was $30!
Mike,you are doing very technical work at a high level,add to that,being a camera man,a show host,a helper,you are putting a lot of pressure on yourself,be kind,to yourself!
Mike, Is the 170 deg. Setpoint the actual water going to the faucets in the kitchen and bathroom?
Just my opinion, but of your various intro themes, I feel that the one you used in your 'Don’t Flush Toilets! Plumber Replacing Cast Iron Waste Piping in Basement with PVC' video (and others, of course), is by far the best.
Edit... Wait, so this is street parking, with 'commercial'/passenger being $7/$5.50, $17/$14.50, or $30/$5.5 per additional hour?? WTF does it matter if it's commercial or passenger? If it fits, it sits... Different story if we're talking about a vehicle that takes up two (or more) spaces, but if it fits in one space, WTF? Welcome to the 'great state' of Zoo York. So glad I split 20 years ago. Hope you can build your footprint in SC and FL, and maybe other places, and give zoo york the #1 salute on your way out. With all that's happened in NY, especially with 'certain' fines imposed on a 'certain' case, I'd love to see companies incorporated in NY peace out and move their incorporation elsewhere, leaving NY a corporate wasteland.
Edit2 - so we have, at minimum, 1,100,000 BTU in water heaters and boiler... So let's just say that it's 1-1/4", which is kind of what it looked like... and with the absence of regulators, we can probably assume 8-10 IN/WC. If we assume even 10' of 1-1/4" pipe, we're talking 793k BTU capacity. If 20' of 1-1/4, now we're talking 569k BTU. It just keeps getting worse and worse.
Again, with the absence of regulators, that suggests that the pressure in those pipes is 8-10 In/WC or so. That's what is typically called for. In video, it's hard to say for sure, but it seems like the gas pipes are WAY undersized for the load.
parlking is a complete rip off ON THE STREET
MJF Mechanical is back!
who?
unrelated question, who do you guys use for company uniforms? The patch with american flag looks awesome
redkap.com
170 set point? Holy crap lol. Most I usually set them at is 135. Had one recently give me flame failure cause the burner coil was full of water. Didn’t see or hear a leak but it wouldn’t run until I vacuumed it out. Haven’t got the call back yet but I told them they need a new one if it fills up with water again. (Leak on heat exchanger)
You can get some water from condensation. Does not drain out. So they suggest vacuum. For me everytime it has been the heat exchanger.
I’ve had a few of these become completely blocked with rust and debris at the flue outlet.
the hose that is unplugged on the fresh air on both why is that ?
Curious what gas pressures would have looked like with all those gas appliances running simultaneously.
Good question.
👍🏻👍🏻
You need some grey goose
I'm willing to bet that the kitchen exhaust is sending greasy air to the intakes for those water heaters. (And boiler.) That will foul everything up in short order.
Huge possibility
hry mike 1 1/2 you cant touch your thumb and fore finher... 11/4 you can
Interesting that the unit had blocked vent fault, wouldn’t the first thing you check not be the condensate or bottom exhaust elbow? Maybe I missed that part of the video?
pulled cap on bottom of condensate tee - was clear and not worth showing on camera
@@PipeDoctor so if it’s clear at the bottom under the condensate cap it’s safe to assume that there’s no buildup in the condensate tee or appliance flue area? Just wondering, I’ve only worked on a couple of these. I’m just wondering why the unit would display blocked vent if the flue is clear. Great video btw.
30:00 😂😂😂 Real Deal HVAC
Nobody's perfect. But it's all about keeping your cool, working the problem, retracing your steps, & and being able to say..."Geez, I'm an idiot. I left the d@mn wire off." I live 5 minutes from A.O. Smith in TN. My sister works there.
😆👌😎👍
We like AO Smith tanks
Because it's so much easier to just jiggle the wires, hit it with a hammer to clean the flame rod from outside the unit. Said `Bill and run, it's how its done NY/NY `the last outfit.
I had account on that street. Shipping company next to hotel
cool!
we all have those days to many things on your mind
Check out the guy at the on the bike with his coat tails flapping around in the wind bought to get snagged in the wheels.
Almost!
The hot water outlets should be tied together and in the center of that connected to the hot water supply our one of those heaters will always be doing all the work. Thats most likely why the right one was changed first the water flow will favor that one the way its piped.
Agreed
Something else to watch on those. That carbon conductor ignition tends to get resistive with use and time… so sometimes intermittent light off, or just doesn’t light. I replace them with regular ignition cable so that issue doesn’t come back. Also, the retarded opening of the gas valve is normal. It does a pre ignition spark for a few seconds. Common on big btu boilers.
I would love to know the DOB person and coned person who approved that unsupported gas pipe and turned it all on
If you can touch your index finger to your thumb, it's 1 1/4
Hummm
#1😂😂😂😂😂
Damn you quick!!!!!
Lack of and wrong type of hangers, pisses me off !!!
sucks!
I didn't think doctors accepted tips
lol
And Eric Adams thought that New York City was the Best City in New York. 🤪 He Mistakenly Confused Best with Worst. What a Huge Disappoint he has been.👎
Swamp rats don’t just live in DC !
it didnt cost you $30 ... it cost the customer $30 lol ... to quote JPP ... hope that guy has a Swiss bank account ... was that job Over / Under $3,000 ?
Under :)
Lack of coffee bro. Lack of coffee leads to mistakes
Yeah true
The last company i worked for had me in the city 98% of the time. I got to service many many kitchens and offices. The customers out there almost always feed you. This one Michelin star restaurant would always make some amazing dishes for me. For 4 years i did that but now, nobody could ever pay me enough to ever work in that liberal shit hole city
lol 😂
