I live in an extreme canyon with 2 creeks, thus the septic tank pumps uphill @ 50' height to a sand filter on a terrace on a mountainside. The Goulds pump is a WE05hh, at least according to my old blueprints. The engineers spec was for pumping 16 gallons per minute at 26' of head. However, I measured the height and found about 50' of head. Since I have a 3000 gallon tank there and I see 20 psi near the septic tank, 20 x 2.3= 46 psi. So much for the septic engineer. Right now, I have a siphon in the tank to keep it at normal level until I get a pump. The tank is also on a terrace, so a siphon works here. Not a good long term solution where the creeks are concerned.

Thats a 1,000$ pump now, but the curve works for my height of 50'. I recall that the engineer paid for the replacement of his original 26' head pump - learned an expensive lesson.
I want to go to a standard clear effluent submersible pump, or even a potable water submersible, as the pump is in a screened chamber. Pump suggestions? The Franklin bottom feed cistern units? [its wired for 120 volts, 2 wire pump.] Seems most of these have too high a head at 50', and I don't want to over dose this sand bed. There seems no easy way to throttle the pump output to 16 gpm at 50', as all piping is buried.
