Peerless Boiler Keeps Blowing Pressure Relief Valve

I have a Peerless Boiler that has a problem. It keeps blowing the safty pressure relief valve on the boiler itself. I replaced the pressure relief valve on the boiler and it keeps going off venting steam with the new one. At the same time, I have to keep adding water to the system and the biolers low water cutoff keeps kicking in. Please advise me on what my problem maybe. Thanks a lot.

If you have a bladder type expansion tank, chances are the bladder has gone bad, requiring tank replacement. If it's a conventional tank, it's likely flooded & needs to be drained.

Peerless Relief Valve Problem

This is a steam not a circulating hot water boiler.

You may have a defective pressure control. Or the line frm the boiler to the pressure control may be plugged. It is not hard to check and fix but you should do it immediately or have someone do it for you. The boiler should operate on about 1.5 to 2 psi and if it is opening the relief valve at 15psi, you have a serious problem.

Sorry, didn't realize it was steam. By all means get this checked out NOW. Before opening any place which could have pressure on it, make sure the boiler is cold. DO NOT TRUST THE PRESSURE GAUGE. Even 1# of steam will take the hide off in a split second. My advise? Call a pro.
