Deep well pump and separate reservoir pump

[javrsmith]

Existing installation is a 150' well producing 1.5 gpm. 20 gal pressure tank. 70 foot static water level.
I'm adding a 750 gallon storage tank with a separate jet pump.
Deep well to fill the storage tank at slow rate with a float control.
Storage tank is going to be providing water to the house with standard 40/60 psi pressure switch.

Should I put CSV on both systems? I'm thinking of setting the deep pump to 25/50 psi, low flow.

Thanks for any tips.

You can use the CSV on either or both pump systems.
