    “POP” or “SAFETY” means Vapor system like steam or air compressor storage tanks etc.

    Relief normally means liquid like water ASME/NBBI/GAMA/AGA etc.

    Now if it IS popping open then its pressure If it is seeping open its temperature.

    Have you checked the pressure rating of your valve?

    Are you talking boiler Or hot water heater?

    If your talking boiler then Check the following

    1- Expansion tank either type bladder or air tank to make sure its not flooded or ruptured bladder CHECK your gauge pressure

    2- Check your automatic feeder is SET for 12-15 PSI Max

    3- If you have a tankless Coil it could have sprung a pin hole and its causing street pressure to cause your relief valve to discharge

    By reading your gauge you can determine a lot about the going on of a system.

    Do not let this condition to continue better call a Licensed Master plumber to check out this system ASAP

    Have a great holiday
