irrigation well question

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? Is that all it could be?

I don't know what a "Plug" is in a well.

I do know a 1.5hp self priming centrifugal should be able to pull an awful lot more water than the normal 2" well can give. You may wasting electricity in a large way.

If the pump is good, you have no air leaks, that leaves the well. I doubt the check valve would stop water from moving altogether. Check the water level, it must be less than 25 feet down. If so, buy or rent a Pitcher Pump and see if that will lift water.
