I have a peerless boiler and the presser relief valve was leaking water (30 psi) for few days. I was able to change the pressure relief valve and expansion tank to see if there was an issue. Water is still leaking through the pressure relief valve after I changed them. I have a pressure reducer valve before the boiler (12 psi B&G Model FB 38) and I tried to adjust the pressure on the pressure reducer valve but pressure still over 30 psi. Would it be correct to say that pressure reducer valve needs to be replaced? Any other suggestions?
