I think that as long as the drain/fill times remained a constant, it would probably work.....but, I wouldn't do it if it were me. I would want the pump on/off circuit actuated by something more directly influenced by the water level itself, rather than elapsed time.

I still like the float idea, and I still believe it could be accomplished safely and reliably without taking out a second mortgage. It just seems to me to be the best fit for the situation at hand.


"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
