LPD system help

[awill99]

I have a LPD system installed in 2010. I recent;y noticed that when the tank field was saturated by rain the tank that has the pump had a continuous stream of water comimg into the a tank thru a pvc pipe near the top of tank and the pump continuosly cycles sometimes for 2 or 3 days until the field dries up. Anyway to prevent this? Check valve?

Sounds like a fundamental pitch problem or drainage problem. The pump chamber pipe should always weep when being used. Having it on continuously for 2-3 days is not normal. Has this happened in the past or just recently?
