The label on it will list what pressure it is set to.

how to bleed air out of hot water baseboard


hey beenthere
Quite right about the T&P valve being the wrong term. and..
I have yet to see a residential pressure relief valve that wasn't factory set for 30 PSI. with a 650,000 btu range max.

Have a couple of them around here. Mostly on older homes that are 4 story.

how to bleed air out of hot water baseboard


hi, i think i did something wrong.. Hook garden hose up to faucet on return. turn off boiler. Close ball valve between where hose is connected and return pipe. Open faucet. Manually open zone valve. Pull fast fill lever on auto feed up so it feeds water quicker... i muct have opened it for about 45 seconds .. I did see light brown water the hose was throwing out with the air bubbles , then I closed the faucet, opened the ball valve, put the zone valve auto mode, turned on the boiler, that all is fine... but now there a copper pipe at the back which is continuously throwing out water. I had to turn off the main ball valve water supply that is feeding that warter to this system. When wver I open that valve water starts leaking in huge amount from that copper pipe at the back

any suggestions?

thanks

Auto fill is probably bleeding water through when it shouldn't. The manual water valve shouldn't be open. The auto feed is not a low water prevention device.

What is the pressure reading on your boiler?
Your pressure relief valve is venting because you are getting too much pressure in your boiler or the pressure relief valve is not operating properly.
There is a chance that the pressure relief valve tried to reseat when debris was going through it and that debris has lodged on the seat of that valve keeping it partially open. There is a flip lever on the end of the pressure relief valve that when lifted up will manually open up the valve to hopefully release the debris off the seat. Water will pour out of the 3/4 " tube when you do this. Release that lever and let it snap back into place.
If your lucky this may deal with the problem.
If your pressure reducing valve is allowing too much pressure through into your boiler and the pressure relief valve is not continuing to vent at a pressure below 30 PSI, then you can turn off the water feed valve to the boiler and still use the boiler. This would be a temporary way to continue to heat your home until the pressure reducing valve is replaced.
If the pressure relief valve continues to vent at a pressure below spec (30PSI) then you can't turn off the water feed.

I turned off the heater system and now the psi is below 30.. so i fliped the lever on the end of the pressure relief valve .. and put it back....still no go.

now when i turn on the system ...in that copper pipe i still have water leaking but at a lower speed.. so now sure if i should leave the system on?

Well according to earlier posts you already have a guage that is probably at least 20 PSI higher than reality so it's hard to tell what is what. You can run the boiler with the water feed on and a dribbeling press relief valve and you'll be heating water that you are draining away. It will be like leaving a hot water tap on all the time, plus the air problem will only get worse. If you turn off the water feed, you may damage the boiler while the relief valve is still leaking.
This boiler needs a serious make over for all the reasons given on earlier postings. The longer you delay that, the more it's likely to cost you.

Tun off manual water valve. Leave water out of boiler until it drops to 12 PSIG. Turn boiler back on and observe its operation.

Did everthing and still that water was leaking..
time to call the professional ... they guy came in and said that the press relief valve is bad... he replaced it and its back to normal. He measureas the PSI in my house it was 120.. that is comming from outside town..

He also mentioned that are couple wrong like the .. gauge is not working .. and there is a small black box that is connected in the wrong place and the spiral that takes off any air from the system... also he is going to install a pressure relief valve to the main supply becasue its 120 psi.

I would thank eveyone for such quick replies and great suggestions.

Getting a house pressure reducing valve installed will also save you years of standard hot water tank life, Hwt T&P valves, solinoid water valves in washing machines & dish washers, rubber supply lines, tap washers, etc. as well as the life span on that new boiler pressure reducing valve.
