I have a 1-hp submersible pump (inlet 246 ft. down from wellhead, static water level 165 ft. down) that pumps water through a check-valve to a holding tank 165 ft. above the well head (via an open-ended feed pipe at top of tank). It was controlled by a float switch in the holding tank, but the conductors between the float and the pump panel have become compromised somewhere in the 1000 foot plus, conduit run, requiring visual tank level monitoring and manual control of the pump. Pulling new wires is not feasible.
Somebody suggested extending the feed pipe outlet to the bottom of the tank (introducing a small static pressure in the pipe that varies with tank level). I’ve pretty much dismissed that idea, as the small (~3 psi) fluctuation would require an extremely sensitive/repeatable/low-hysteresis pressure switch that may not even exist. Plus, the bottom feed would tend to stir up sediment each time the pump runs.
I am aware of the wireless transmitter/receiver concept, but I’d like to avoid the huge expense associated with that system.
Is there some way to turn the pump on/off by utilizing a bladder tank/pressure switch at the wellhead? Since the feed pipe dumps water into the air space in the tank, I suspect the answer is no, but maybe there is some magic outside-the-box method that I’m not visualizing.
