Wow and all these years as a PRESSURE vessel and low pressure boiler inspector I certified PRESSURE vessels with a working pressure of over 1,500 PSI
TSK, TSK another reason WHY folks who dabble in trades should open up their minds and not their mouths and READ ASME/ASTM/NFPA/ASSE/NBBI/AWS as far as actual working pressures publications
The T&P setting is based on BTU INPUT and temperature and according which code your using AGE or ASME what the valve will be rated at.
The AGA sets much higher standards.
Also the actual “tank” if ASME designed has a Working pressure rating much like a boiler plate.
Contact Watts for the EXACT replacement of the one you have Or a greater relieving capacity never less then actual BTU input. Amazing how the unknowing give erroneous advice constantly.
It still amazes me how some states give a license away to the unknowing.. NOW more then ever I think home centers are Par with some of the so called “plumbers” out here.
One of the major flaws with giving away a plumbing license is folks who get these non skilled licenses actualy believe they know something
SylvanLMP still trying to learn these trades properly
