I have a submersible pump,......I believe it is a 1 hp, but not positive.
Running a 40/60 pressure switch and a bladder tank along with various filters, and softener.
A couple of days ago I changed the non-functioning pressure gauge and slightly adjusted the switch settings to get a true 40/60 range.
Drained the system down, and checked the bladder tank pressure. It was only about 18 psi, so I added air up to 38 psi. The bladder tank is fairly old but it seemed to take the charge, and also no water coming out of the schrader. It says 33 gal capacity, but the drawdown rating is not readable any longer. I presume the low air charge could be from loss through the rubber over the years,.........I admit I have not checked the pressure for a very long time.
Onto the real question!
With no water being used in the house, I used a hose to drop the pressure to 40. Close the spray handle and the pump brings it back to 60 perfectly.
A plumber friend of mine says that my pump is shutting off too quickly, and that the pump needs to run for a minimum of 60 seconds in a fill cycle for proper cooling.
From pump start at 40 psi cut-in,........it only takes it about 20 seconds to reach the cut-out of 60 psi with no water being used anywhere. Sounds to me like everything is working correctly, but he says no, and that I need a much larger bladder tank.
Is he correct, or is he nuts, and everything is normal?
Thanks for any info provided!
