I have a situation dealing with an RV pump providing water pressure in an older Cabin, which was retrofitted with all 1/2" PVC. The pump has an internal non-adjustable pressure switch. Cut in is at 30 PSI, cut out at 45 PSI, and the flow tops out at 5 GPM.
The pressure tank they want to add is small, I would say no more than 2 to 3 gallons. It's painted red with no spec label so I would say the tank is from China or Taiwan. It has an air fitting on top for adjustment or filling.
What should the charge on the tank be at for best performance at these pressures and flows? Can you tell me the math to use in figuring it out if I ever have to do this again?
Seems like a lot of the cabins in the area have these pumps and someone on the net sold a bunch of those tanks to folks around there with the pitch that they would keep the pumps from cycling so much, and being so small, were better matched to those RV pumps.
Thanks
