We only use the pump for irrigation and have had this problem for years but it seems to be getting worse. I installed a new presser switch and gage because the old switch ruptured sow I know these are good. The problem is the Well will cutoff at 30psi when not using water but when we start to use it the well drops to cut on presser (15psi) and slowly drops to below 10psi and never recovers. What could be my problem?


Well is about 20 feet deep
2 inch pipe I think
pump is 60ís vintage
