Here is a drawing using a sub in the cistern.

I believe that is a deep well jet pump only.  You will need a shallow well jet pump or at least a convertible jet pump to draw from a storage tank.  You can also use a submersible well pump in the storage tank instead of the jet.  Here is the wiring diagram to bypass the switch on the side of the motor.  See "Jet pump" wiring.

Won't do any good to have two CSV's.  Water will take the path of least resistance anyway.  What I normally do to fill a storage tank but not starve the house for water is use an electric solenoid valve with pressure sustain to fill the storage tank. Setting the pressure sustain at 40 to 45 PSI means only the excess above what the house needs goes to storage.

If you get the right high flow low pressure submersible like a Grundfos, the amps at low flow drop considerably and it is fairly efficient for the heat pump.

If I am right about the 20 PSI needed, a storage tank would need to be 46' tall.  Using a booster pump to draw from the storage tank and produce 20 PSI to the heat pump probably won't be much different than just running a high flow low pressure well pump. Especially because the water is being pumped twice.

Add in the pipe, elbows, and other fittings going in and out, plus the electric valve itself has quite a bit of friction loss.  You can always turn the pressure down if needed, but people usually want to turn up the pressure, not down.  Also not much difference in pumping energy cost between filling a tank at say 10 PSI and going straight to the Geo at 20 PSI.

Hi Don
I don't think you can run the Geo system at 2 PSI.  Most geo systems need about 20 PSI to overcome the friction loss in the heat exchanger coil.   Have you looked at how we do a two pump system for a Geo?  You don't need a storage tank because you have millions of gallons stored in the well.  You don't need a very large pressure tank because the CSV will keep the pump from cycling.

A small pump in the well working with a 10/30 pressure switch and a CSV set to 20 PSI can supply the geo by itself.  The low pressure well pump can also supply water to a small booster pump as well.  The booster pump has its own pressure tank and pressure switch working at 40/60 with the CSV set for 50 PSI.  In this way the well pump feeds the geo, and when the house needs water the well pump and the booster pump run at the same time.

I check this forum on weekends as well.  Let me know if I can help and how it goes.  Thanks  Cary

Did you get it working?

A long sensing tube is fine as long as attaches after the CSV.  Text a picture of the system to 806 749 6289.

If loosening the adjustment bolt made the pressure drop to 10 it is working.  It should be barely in at all for 40 psi?

You just loosened the bolt to much.  Stop when it is holding 50 while the shower is on.

Submersible pumps come with a check valve but you need to add one with a jet pump.o

It looks good!  You are just turning the adjustment bolt the wrong way.  That bolt needs to almost all the way loosened out to hold 45 PSI steady while running a 3 GPM shower or hose.  Everybody turns it the wrong way for some reason.  Just let me know how it works.  Thanks

The PK1A kit will work great with that size pump.  It is easy to reset if needed.  If the pressure switch is still set to 40/60, set the bolt on the CSV1A to hold 50 PSI constant while running a shower.  And yes just use the 40/60 switch that comes with the PK1A kit and wire around the existing pressure switch as shown in our wiring diagram under "jet pump".

Valve Tech / Re: CSV125 Leaking When Power Goes Off

If it continues to leak the o-ring is not the only problem.  The tube that slides through the o-ring is either scratched with sand or slimed over with something like iron bacteria.  If the tube is scratched a new o-ring won't help.  If it last less than a year we will warranty it even if it is sand or something, but we would prefer you use that credit towards a CSV1A that can handle debris without any problem.

Sure a jet pump will draw from like 24' deep if needed.  However, the way you describe the suction line means there is a huge high spot before it gets to the pump.  That high spot will trap air and gulp into the pump causing a loss of prime.

If you can't draw from the bottom of the tank you should set the pump up high so the pump is the high spot in the suction line.

You could also drop a submersible in the cistern and pump up and over without any problems.
