    Let us all take our boiler work very seriously.

    I forgot about the water heater KABOOM. I think I'm going to bookmark that to my cell phone, and show the customer who debates me on why they should have the PRV replaced.

    Good practice is whenever you lay hands on a boiler or a water heater for whatever reason.....

    Always tell a customer You are going to have to test the pressure relief valve or temperature and pressure relief valve.

    To do this I will have to manually open the valve, it may or may not reseat. If it doesn't reseat then you will need a replacement safety relief valve. This is for their safety. Always test, even if it means having to go get a prv or T and P relief valve.
