I have a 120' well used for irrigation here in south Florida. Pipe is galvanized 2 & 1/2". Pump is a 1 & 1/2 hp Goulds centrifugal on a concrete slab next to the well pipe.
After the pump was left unused for 5 months during the rainy season, it is losing prime within minutes after shut off.
First I replaced the horizontal mounted check valve between well and pump. No change.
Then I brought pump in and had it rebuilt, as it was probably 12 years old anyway. No change.
I can get it to prime by attaching a hose to the bib on top of the pump, and running water in while the pump is operating. After 10 or 15 minutes the pump will prime. Once primed the pressure is excellent.
There is no lack of water as the water table is now about 4' below ground surface.
Any diagnosis?
Thanks.
