Have a Delavan pump with a bad pressure switch. Is there a replacement for it? I did take it back to the place I bought it from and was told a loose connection. Hooking it back up today ran for 30 sec. and quit. After testing all electrical I took the switch and with my Fluke meter found the switch not closeing. ran stait power to the pump it works fine. Or do they make a pressure switch that I could put in line and then wire the switch? Trying to save this brand new pump (1 month old). Thanks.
