Hi, new to forum and have a pump priming issue.
I have a 1 HP Sears pump to pull water from lake for lawn and landscape irrigation. This summer, the pump began losing prime overnight. When I refill the housing, the pump runs fine.
There are no visible signs of water leaks. So, suspecting a leak somewhere on the intake, I inspected and replaced the all the PVC intake piping, even though I found no evidence of a bad joint. I inspected the swing check located on the inlet and it is clean and clear, but it still loses prime overnight.
Now I’m thinking the shaft seal may be bad… but it does not leak water during operation???
I can’t think of anything else to look for. Does anyone have suggestions?
Many thanks in advance.
