An Update on 2 Pumps in one well. Yes, it was a tight squeeze getting the 2 pumps in one excellent 8" well. And yes, if the new 3/4 hp Berkeley, set at 100 feet dies first, I'll have to pull the 1/2 hp Franklin. I did enclose the Berkeley wires passing the Frankin in a 3/4 conduit to avoid...

Sounds like a salesman with a calculator. "Only 36 cycles per day is still 13,140 cycles per year." Well, who runs their heat pump 365 days a year ? PS I did buy a CSV ....

Your math may be right "Cycling every 10 minutes is 144 cycles per day", but who runs their pump 24 hours a day?

I understand that the small bladder tank only softens the many stops and starts of the pump. If you brush your teeth, it turns on and off. As for the pressure setting, Franklin Monodrive recommends 70% of set pressure. So a system set for 50 psi, would have a pressure tank setting of 35 psi...

That's a good point Valveman. I'm not looking forward to pulling my hand pump, just to replace my submersible.

I made an error on the well diameter. It is 8" (not 6") and has a depth of 220' but pumps non stop 30 gpm @ 120'.

Thanks Valveman for your detailed response … but I like the idea having 2 submersibles in one well for redundancy purposes. With a couple extra lines and valves, I could use either in case of an emergency. My heat pump runs off the well and I wouldn’t want to have to pull it mid winter...

2 pumps in one well Presently, we have a 1/3 hp @ 80' and are operating both the heat pump on stage one and house satisfactorily. I've purchased a Berkerly B15P4MS to replace the 1/3 hp but I thought 2 pumps might work: one operating at 25 psi (HP) and the other at 50 psi (house). As you say...

Can I install 2 submersible pumps in one 8" well. One pump for household needs and one to feed the water-to-air heat pump. The well produces 30 gpm at a draw down of 60'. Yje well is 220 ft deep. I want 6 gpm for the household using a 1/2hp submersible (set down at 80') and 7-12 gpm for the...
