Have an irrigation well with 30' depth, 2" pump input and check valve, 1.5hp
pump. This setup has delivered great water for the system. Saturday, the
pump ran but nothing coming out. Went ahead and primed it, but no output.
The guy that dug the well said "well, it's either a bad pump, a bad check
valve, or I need to go back and maybe move the plug back down.

Monday, I took the pump to local pump shop. They told me yesterday nothing
was wrong. Although I've not heard of a bad check valve, I'm going to
change it today.

Any thoughts on where our problems are? Am I missing anything?
