hello everyone. I’m a plumber for many years but mostly work in new construction projects. My hot water boiler safety relief valve was leaking. I noticed it stopped leaking and the pressure dropped to 5 PSI. I opened the pressure reducing valve and it brought the pressure way past 30 and was climbing to almost 70 psi. I shut off the prv and it was still feeding water into it. So I shut off the my water feed, and knocked the pressure down to about 25 psi. Should I change the PRV as well as the relief valve? I’m not too familiar with the pressure reducing valves and how much they need to be opened.
