your make up water pressure is greater than the safety relief pressure. The safety should be 30psi lift. the makup usually goes through a regulator called an automatic makeup valve. these valves operate infrequently on a closed system and get rusty. They stick. If yours is stuck open, then your makeup water pressure which is probably greater than 30psi is overpressuring your boiler.

The compressor keeps runing and will not cut out on the pressor it is set on the new switch it is electric compressor


If the pressure relief valve ( or "pop off" valve as we call it ) doesn't relieve the pressure by letting out air then your gage that you are using to determine the pressure may be faulty. Use a tire gage to double check yor pressure gage or just put another gage on.
If this is a "oilless" compressor then the rings may be bad.

Hot water leaking from what i think to be the pop off valve. i tried to tighten it a little and it started leaking more. The unit is 16 years old. The excess water is draining into the catch pan and then...


Hello
16 yrs old? Im guesing this is a hot water heater.Not a air conditioner.

If its still making hot water you may not need to replace the whole unit.
The valve that is leaking is a high pressur relief valve and they do go bad the sprigs become weak over time and some corrosion may not allow the valve to seat properly.

1st step is to shut off all incoming and out going water to the tank.
2nd Shut off fuel or gas to the unit, and annonce to everyone your are working on the hot water heater.
3rd at the very bottom should be a drain valve much like a hose spicket,open this slowly and drain the tank,remember the water will be hot.You may not need to drain it all the way,while draining pop open the relief valve,when you stop getting water from it,you are below it and can turn the drain valve off.
4th remove old relief valve and replace with a new one,i think they are rated at 15 psi or 30 psi blowoff pressure,hopefully there is a tag on it with that info.

When you go to install your new one use some pipe thread compound or teflon tape around the threads before you reinstall valve.
Once done slowly refill tank with water, check for leaks.When full open up hot water valve to house and relight buner.open a faucet in kitchen to hot to bleed off any air.

Old house with old water cylinder, water pouring out of the spout and larger than normal electricity bill?


Hello grant.... You must stop that water flow immediately or your bill will be even larger next time it arrives. If the water is pouring out of the spout attached to the pressure relief valve you may simply need to replace that valve. To do so, turn off the power to the tank and use a wrench to remove the pressure relief valve. GO to any hardware store and get an exact replacement valve and a small tube of plumbers pipe dope. Dope up the threads and install the new valve. Joe

Whats the routine for fitting a new expansion tank? HELP At what pressure should the overpressure relief valve lift?


Hello, not know the size of your system I can only give you the standard answer. Most expansion tanks are sized by the amount of water they will hold, however a rule of thumb has been a smaller 4 zone system will have a 7 gallon tank with 12 psi charge. Larger systems will sometime go has much as 30 gallons but, the charge is still 12psi. The relief valve should be a 30psi set but, again on larger systems it will be 50 psi. The 12psi is a standard auto fill valve max and you want to match the charge of the expansion tank to the auto fill valve setting. Hope this helps.

My f28 boiler is letting water out all the from the run off valve


Hello

This is a relief vave,probably rated for 30 psi.You either have air in your heating system causing the pressure to go up.

Or you need a new relief valve,sometimes the springs wareout or rust and iron from the water keep them from reseating properly.

You should have 15 to 20 psi of pressure on the boiler if its 30 or over you need to bleed air from the highest radiator or baseboard,if there is a 2nd floor go up to one and find the bleeder and bleed out air.Be carefull once the water starts coming it will be hot.

Worcester 24i junior boiler about 5 years old making banging noise and losing pressure thro overflow can you help.


its getting to hot /either your water level is low in the system /the circulating pump coupler could be broken; so water may not be circulating through the pipes, this will cause relief valve to blow ..air may be in the lines also/let me know if you need more info/good luck/joe/
what does the pressure guage read it should be reading 12lbs at the lowest an 30 at the highest/the relief valve will blow at 32 lbs this depends on how many floors or levels you have ..
