Why is the relief valve leaking? | 2017-10-31

This takes our normal system pressure to 29-30 psig. The next step is to verify the pressure rating of the relief valve. The pressure rating of the relief valve should be at least 10 psig higher than the operating pressure of the system but less than the maximum allowable working pressure (MAWP) of the boiler.
