    the word is "hundreds" of psi, as in pressure capable of bursting pipe and connections - if you have a 350-deep well, pump set at 300 feet, the water pressure in the full-of-water drop pipe will be over a hundred psi above the check valve on the pump discharge, and that is before you energize the motor

    are you saying there is atleast 125 psi loss at the top, at ground surface level?

    That particular pump cant get it up?

    I do believe a pump that deep might have multiple check valves on the drop pipe, so the entire height of water column would not necessarily be pressing against the top of the pump.

    If we install a drip zone ( we only use hunter pro c clocks) we will wire it to the MV tap , then shut pump off for zones we don't want it to run with. Example , we want drip to run for an hr. zones 1-2-3 set for 20 min. Pump switch on. Pump switch off for the rest of the zones. Although Im sure fla has a lot more systems with a well just for irrigation then I see.
