A.Y. McDonald has added 100 PSIG pressure relief valves to its line of relief valves in 3/4”, 1” and 1 1/4”. The line currently includes pressure relief valves 1/2” through 2” factory set to open at 30 PSI, 1/2” through 1” valves set to open at 75 PSIG, and 1-1/4” through 2” valves set to open at 65 PSIG. Accidental sticking of the pressure switch can cause the pump to develop pressure that could burst the tank but with the installation of an A.Y. McDonald pressure relief valve, this scenario is no longer a concern.
