Pumps, Wells, Tanks, Controls / Re: Well with CSV1A holds pressure then drops suddenly

« on: May 14, 2018, 01:16:15 PM »

Thanks for the info. I just tested it and ran twice as many sprinklers and it ran solid with no weird pressure drops what so ever. I am certain I have it wired correctly. I've tested the voltages at the pressure switch and the pump control and I'm getting two 118VAC lines coming in. The pump is now 6month old but has only had limited use. It's a 4-wire 1HP 18A pump. Pump controller is for a 1HP as well.

To test the well initially I ran a 3/4" ID hose wide open for 12 hours and I never noticed it cycling while I was there.

I'm going to go back to the installation manual and run through it all again from the beginning. If this was an irrigation setup I wouldn't worry but it's going to be primarily for a house and I can see demand being as low as 1-1.5gpm (shower, doing dishes, etc) quite often. Should I have got a different cycle stop valve?

Pumps, Wells, Tanks, Controls / Well with CSV1A holds pressure then drops suddenly

I've got a well pump with a CSV1A, pressure switch 40/60, gauge, and 12gal expansion tank. It's a new system that puts out 18-20+ gpm when tested. My problem is that after setting up the expansion tank to the pressure tank and pressure switch per CSV instructions it cycles way too often. I'm testing it with two good sized sprinklers that I run full open out of a 3/4 ID hose. The system is literally only a submersible well pump, 1-1/4 sch 80 pipe (75'), about 6" of 1-1/4" stainless, the CSV/gauge/pressure tank and a 1" hose bib on top. I haven't got it running right so I haven't hooked it up to the house yet. Can supply pictures if needed.

The system runs at 45 PSI and holds it perfectly for maybe 40-50sec and then the pressure drops to damn near 0 and the pump kicks back on. It runs for a little back up to 50psi or so then kicks off... holds 45psi for another 40 seconds or so and drops to nada again.

I went to school for mechanical engineering so the mechanical and electrical system makes pretty good sense to me. That said, I never ran one of these systems so I'm pretty sure there's going to be some dumb "ah ha!" moment in my future when you guys help me iron out what I've done wrong.

Any other information needed to help me with this?
