Drain line issues!! HELP

[JohnT]

Once the water gets so low the pump will have a harder time lifting it. The difference in height between the water level and the inlet of the pump is the key, and pool pumps aren't really designed to do a lot of lifting of water. Probably no plumbing problems.

I guess its time to buy a submersible pump.

Filter has two settings, operate and backwash (Waist).

My theory was that the pump would not be able to lift the water and it appears that is what happened. It stopped pumping when the water level got about 4' below ground level.

Finished pumping with a small submersible, now just waiting to have the liner replaced.

oh, ok, I guess some filters have a seperate "waste" option that bypasses the filter all togther. Seperate from a "backwash" option.
