I bought a house 3 years ago with a 550 ft. deep well. The pump is a 2 hp Goulds pump with a 2 hp Franklin motor that was installed just before we bought the property.
The air/pressure tank is a 75 gal. non bladder galvanized tank. When the old garage was remodeled into a big room the tank was relocated into the new garage.
The pump was putting out about 7 to10 gpm, and 2 times a year I would drain the tank and refill the water to the air bleed screw. This fall I added a water line to our barn and pastures, tapping into the waterline in the pump house. I replaced the pvc piping and backflow valves in the pump house and added a cartridge filter. Inside of one of the old pvc joints was almost solid dried pvc glue.
Now the pump is putting out 15gpm+. The pump is constantly short cycling. I have the pressure switch set to cut in at 26 psi and cut out at 50 psi. The pump will run for 5 seconds and shut off for 10 seconds when you shower, causing a big flocculation in the water pressure.
Draining and refilling the tank to the bleeder screw no longer makes no difference.
Will a bladder tank solve the short cycling? And if so, what size.
