You can keep the pump . . . provided you always, or almost always, run on low speed. Use high ONLY when you are cleaning, draining, or something similar.

Yes, that is what I was hoping/planning. At the moment, the speed selection is by flipping a switch, but I am, after all, retired..

Note the change in gallons: pool volume is water depth, not pool depth. (I assumed that the 4' dimension was the pool depth, and not actual water depth.)

And I reset the change - I did measure the actual water depth. There is about 10" of pool above the water level.

Forgot about the suction leak! Read http://pool9.net/leak-s/

Thanks - after reading that article, I found that there were a couple of threaded connections that were leaking - a bit of Teflon tape seems to have helped quite a bit. I suspect that I will find that there are other contributing factors, but this is at least a start.
