Unhappy Not Getting Much Water From Point

This site is Great...

We are drawing water from a well point with a 1.5" line to a Pump Co duel action Piston Pump then to a 20 gal bladder tank. The foot valve is located just before the pump. The house is new to us and when we first got the house we had the pump re-built. We have also installed a new pressure gauge at the pressure tank and a new control at the pump.

It currently takes 20 minutes to fill the tank to 45psi and it seems like the inlet pipe only flows half full. We have checked for pressure leaks on all lines that we had disturbed on the suction side of the system . We have primed the pump several times but can not get the cap off of the tee at the point to prime the line at the well. We did try to prime the entire line from the backside of the foot valve but the water just drained into the well.

Any suggestions or comments?

Here are some basics:
1. The pipe between the well and the pump must incline. If you use an Elbow on top of the well, make sure that the pump inlet is just a little higher than the elbow. Use a level to check that you don't have any dips or high spots on it's way to the pump. Else bubble(s) develop at the highest point(s) and very little water can get past.
2. Use shaving cream to check for leaks. Put it on thick, then smooth it out. Go all the way around the joints. Look for dimples or pin holes in th cream. Take your time, and look all the way around the connection, they may be hard to see.

Priming means filling up the pump and all the pipe back to the check valve. It sounds as if you are not having a priming problem.

Is it possible that the well is not producing enough water?

How do I check?

It's possible. To check, try and find a clean source of water maybe from a neighbor. Open the well and pour as much water as you can in as fast as you can, preferably from a faucet and hose. If it backs up, then you have a problem, to see how bad a problem, see how much it will take what you put down.

Realize that this is just a rough guesstimate, an indicator of how things should go that's all.

Many people get along fine for household water on as little as a gallon an hour with a large pressure tank. But that's too little for irrigation. For irrigation, you want at least 10 gallons a minute. That's enough to run 3 sprinkler heads at the same time.
