I always shied away from the expensive pumps but now I want an ac/dc submersible for a 120 ft well 70 ft static. I would like to re use the typical 1+ inch threaded drop pipe(the standard size) that is in the well now.I have a Franklin AC 1 hp currently.If price is not a factor what unit would you recommend from the Grundfos/Lorentz/other high end pumps selection that is available now online...? I want to run it on AC and DC.
thanks

    Some answers are needed

    1. Are you on or off grid?
    2. Do you store water (above ground tank) or straight to pressure tank?

    We are off grid and have a Grundfos 3sqf-2 well pump that supplies a 5000 gal. tank.
    We use a on demand pump for house pressure. We are very happy with the well pump.

    We've had an 11 SQF-2 in the ground for 15 years and it works fantastic. Originally it was a separate 48v system but after the 2nd set of batteries hit end of life I just plugged it into the house's solar. Just a suggestion: you don't need the CU200 control box. Just control the pump with a standard pressure switch if you are using a pressure tank(s) Since you want AC or DC sources you will want the IO 101. If you're filling a tank you will have to spring for the CU200 for $500+ or fashion a relay with a power source.
