So after reading many many threads on here and around the internet I can't seem to find my problem.
I have an irrigation system for my vegatable crops. It is a dug well. I have a check valve down the well on a 1" PVC pipe. That pipe runs approximately 20 feet into a barn where I have my jet pump. From there it goes to a 35 gal (somewhere around 35) bladder tank. The pressure switch is a 30/50. Air pressure in tank was corrected to 28psi (had to let a little out as it was 29.4 when I checked it with the digital gauge).
Symptoms. After priming the pump and getting the initial setup going (same setup as last year with no issues then) the pump runs until around 55ish PSI according to a pressure gauge between the pump and tank. I got nearly the same reading from a digital pressure gauge on the tank's air valve.
So far so good. Then the pump will be off for about 30 seconds and start cycling on for approximately 10-15 seconds then off for close to a minute. Pressure on the gauge doesn't drop nor rise, also confirmed with the digital gauge on the tank's air valve. This cycling will continue non stop with no change on the gauge. At one point (after letting water out of the main outlet pipe) the pressure was sitting at ~40psi and the pump was still cycling as above. The pressure didn't change after I let it cycle around 10-15 times to see what would happen. This cycling is occurring without the water being in use.
What I have tried:
-replaced the check valve in the well.
-checked for leaks, nothing found
-reclamped all my connections.
-opened up air valve on pressure tank with no water return, only air.
-replaced pressure switch with spare. No change.
My other thoughts to try:
-clean out the little hose (and nipples) that goes to the pressure switch.
-teflon tape the plugs on the pump that you prime with. Possibly leaking??? Not seeing any water, maybe air entering the system?
-pressure tank is shot? Even though I didn't get water return. But why are the pressures showing fine?
Was convinced one of those things would have fixed the issue. So now what would be the next step as I can't see the hose cleaning and teflon tape on the plugs being the fix. Does this sound like I should be looking at new pressure tanks?
Thanks
