Pressure relief valve

The pressure in my hot water system gets up to about 32 psi at which point the relief valve opens and starts to form a hot water lake outside of my house. Any idea why the pressure keeps going up like that? I am assuming that 32 psi is when the relief valve would normally open, so I don't suspect that to be the problem.

A related item to know is that on Monday I had a new circulation pump installed because I had one zone in the house without heat. This was done by a professional company, not me. Is it possible he forgot to open or close a certain valve or something?

Relief valve

Maybe they did. If they problem started right after the work was done, call them back. Most service people & companies are honest & if they messed up, they will make it right.

What happens alot is the presure reducing valve will not work properly once you drain and refill the system. Its probably overfeeding now after it was used to refill the boiler

Does that mean it needs to be replaced, or is there a fix for that?

Reducing valve

Usually replacement is the only answer to an over feeding reducing valve.
