I've had a lot of heat picked up through a reversing valve that was working correctly so I don't know if I 100% trust that. I think the best would be pressure taps but that's very invasive. It would be nice to know what is a normal drop across that valve. It'd be nice if the manufacturer posted something about it.
@@HVACRSurvival yeah the problem with the valve being made of copper and brass you get a lot of heat conductivity. I've been fooled by it before , and diagnosing a 4way valve I find that very difficult .
Great video on a geo thermal unit. Usually you can use a magnet to which the reversing valve back and forth to see if it needs replacement. But on those it might be hard to do. Nice to use the heat blocking pads and rag to keep everything form burning up. Thank you Rick hope to tune in on Sunday.
@@RayRay-nb7tn when your saying you use a magnet to test the valve, are you using it on the solenoid? I knew the solenoid was energizing when I cycled it but this system should be in heat mode by default with the valve not energized.
@@RayRay-nb7tn I'm surprised there's anything magnetic in it. I will see if I can make the one I cut out move back and forth with a magnet I have a hundred pounder. I've been thinking about buying a thousand or twelve hundred pound magnet for fishing
Good vid , I feel your pain bro ! Going through the trouble of replacing the compressor only to find out the bloody 4 way valve is bad, that will ruin your day right there ! I absolutely hate 4 way valves , but nowadays you can hardly get away from them , it's like every AC unit must have one otherwise it's not an AC unit .
The manufacturer should be using rotalock fittings on the compressors . Great job in getting that back in operation and removing the unnecessary defective reversing valve .
Thanks Michel, I don't like roto locks, normally they never release when used outside so you end up cutting them out anyway. Thanks for the kind words! 👍
I've been to two county fairs a donkey show in Tijuana I have never seen a heat pump radiant floor system always in gas fired or electric boiler never a heat pump obviously they do exist :-) :-) Keep On Keepin On
Well I guess living in Greenville South Carolina they have a reason why I haven't seen that ridiculous crazy system by my opinion keep the flame where it belongs
@@kevinpoore5626 I would say it wouldn't be cost-effective in your region, but because I'm in Ohio, geothermal's benefit you more when you have colder outdoor temps because the ground is always a constant temperature.
Great 👍 work!!!! By the way, where do you purchase the braze blanket for welding/brazing/soldering??? Why is your braze blanket brown colour??? I can Not find one of the same colour???? Thank you, Barry
Nice video Rick. Sounds like they were routing out some drywall or maybe countertops? Great diagnosis of the issue, nice QCB brazing! Smart to get rid of that RV in my opinion! Well done!!!
@@HVACRSurvival DOOO! Glad I didn't have money on that one! 🤪😆 Great vids as usual, very sorry to hear about you and your wife's COVID diagnosis, glad you didn't get hit hard!!! Feel tip-top soon if you aren't already!! 💪💪 Nice that you have a cool employer!!
Once while it was still under warranty they decided the chill loop wasn’t long enough so they put four water heater tanks in series just as holding tanks to kinda let the water warm up before it returned.
Definitely looked like someone put a valve in it already. One trick I do very seldom if I cannot be 100 sure if if it's the valve or compressor I will pinch off the discharge line slowly and see if the compressor amps start to spike.
HVACR Survival you want to see whether the compressor or reversing valve is the problem but typically this is only if your compressor is running but not pumping at all and it’s hard to diagnose that way if the amps spike and the compressor starts to bypass I’d say start with the valve.
Hey maybe the compressor ran with high heat due to trapped oil you mentioned in the video? That can breakdown the motor windings, who knows maybe it was about to have a burnout
@@EverythingHVACR Yep, pretty much👍. It sucks when you know what's probably wrong but you don't want it to be wrong but you're kind of glad that it is what's wrong even though you don't want to do it 😂
Is there any benefits to these units? Compared to like a Natural Gas boiler for example. Hydro is not cheap here in Canada and I don't see how these would be any better than a simple boiler. Thanks.
You shouldn't need your acetylene and oxygen higher than 5psi to braze. If you are having issues at those pressures you may want to consider a new tip or even a smaller one and make sure you regulators are working correctly. By having your pressures as high as you do you're using way more gas then you need to be which isn't good having small bottles. When I was brazing in school I was able to set both pressures at 3 and had no issues brazing anything. Hopefully you aren't having anymore torch issues anymore but if you are you may want to look into some changes with it.
Accents Dunmore I made comparisons to the original torch head to the brand that I am using 4 the upgrade and noticed that the shank in the middle is not as long so I think the oxygen acetylene is mixing before going through the torch tip which would likely cause most of the problems I'm having. What's bologna is the fact that I sent these heads back to the factory and told them exactly which torch handle I was using and they said it would be fine but obviously they don't know their own products. At this point I need to either buy a new handle or some sort of adapter.
@@HVACRSurvival If you're using Victor brand regulators I'd get rid of them and use another brand. Victor is the worst stuff you can buy even though it's expensive. However in reality you're just best with an Air/acetylene torch. You would only have one cylinder to drag with you and still have plenty of heat to braze with. You could easily trade you 10 & 20cubic ft cylinders for one 40 cubic ft 'B' acetylene cylinder.
@@benkeysor7576 the torches in my videos are supplied by the company, my personal ones are much better and have a cutting head. I learned to braze with a B-tank but it won't do much larger than 7/8" and there's times where I'm doing 2" nor has the control I like for delicate work. Everyone's different but I've had both. There's a lot of large equipment I work on that I just can't show in my videos so a lot of times all you see is these little dinky reach in coolers and little walk in systems.
did you make sure the install-clowns didn't wire it to run the floor zone as cooling? I could see that occurring and it hammering the reversing valve to death trying to not freeze up on pressure/temps or once satisfied. never know what darwin work was done in the install/past lol.
I have serviced this for the last several years, it's controlled with a digital T87 basic thermostat. It's really a simple system that's just large. The building has 2 off these geothermal's total for the whole garage wearhouse area. I compared all my readings to the other 3 circuits prior to finalizing my diagnoses.
I replaced the gauge on the fuel tank. I tried what the factory engineer recommend I try and removed the flashback arrestors and it worked fine. He said because I don't use my torches for cutting I should be ok without them. I think they were hanging up because I noticed a difference in the resistance when I blew through them. I prefer to have them so I might replace them with new. I never had any problems with normal tips like a number 2 or 1.
I like your videos man. Your very knowledgeable in refrigeration and I know I will learn from your videos. Has anyone ever tell you, you have big hands almost like a mythical creature. Your hands look bigger than your face. Just messing with you but great video
Great video! Simplest way to verify reversing valve is with temperature probes. Suction temp before and after will prove if its a leaker.

Not on the solenoid on the body of the valve. The valve is not going to move unless energized.

That was electricians mounting something on the side of the metal building.

I had one of these that was a constant nightmare. The coax started leaking and they replaced it. So glad it’s gone.
Once while it was still under warranty they decided the chill loop wasn’t long enough so they put four water heater tanks in series just as holding tanks to kinda let the water warm up before it returned.
We replaced the other unit for the other side of the building already but that was a WaterFurnace. Thanks for sharing 👍👍

No she was a virgin, I like that idea Joe 👍👍. I'll do that sometimes to the suction piping on small reach-in compressors.
I just thought a little deeper on what you said, is there a reason you would restrict the discharge line and not the liquid?
HVACR Survival you want to see whether the compressor or reversing valve is the problem but typically this is only if your compressor is running but not pumping at all and it’s hard to diagnose that way if the amps spike and the compressor starts to bypass I’d say start with the valve.
Great info Rick ... Good vid ...
I never change a hi-vent without installing a baby ball valve there.
Hey maybe the compressor ran with high heat due to trapped oil you mentioned in the video? That can breakdown the motor windings, who knows maybe it was about to have a burnout
I was thinking maybe lack of oil caused some wear in the plates causing a SEAL issue between the plates but can't be sure.
reversing valve have a capillaire and give pressure 2 the valve , sometime s the the capillaire is closed because a bad soldering from the manufacture
Nice video man! If it was easy everyone would do it.

You got to remember, not everyone has natural gas. Yes, they are very efficient for northern climates.

if the tip keeps back-chooching, I'd wonder if the low pressure gauges are accurate or some restriction in the hose/backflash preventers/etc.
