I'm trying to decide if I need to replace my pump. I don't know how old it is, but I think it may be only a few years old.
I am drawing water from a lake. The pump is a Mastercraft 3/4 hp. Vertical lift from the lake to the pump is about 12 feet. The pressure tank is at the cottage about 100 ft up a 45 degree hill. The system had been running fine. The pressure guage at the tank when full was 40 psi - not sure what the pressure at the tank is when the pump normally kicks in, pretty close to zero.
Last night the connection at the pump worked itself apart, the pump lost prime and was probably running continuously for some time (we can't hear it running unless we are down at the lake). We repaired the connection and primed the system. The pump is able to get the pressure up to 35 psi but no higher, and the pump won't shut off. For the time being we are manually shutting the pump on and off as needed.
I'm guessing that the pump may have been damaged by running dry for a period of time. Would it more likely fail completely, or would it pump water but with reduced efficiency in such a case?
Thanks,
Ted
