Questions on sump pump for ground water

[Dr. Spike]

My water table here is quite high. I have a sump pit next to the pool that keeps the water from getting behind the liner. I can't tell you how it was installed, the pool came with the house.

It is located on the deep end about 5 feet from the pool. It is 2 feet in diameter. I don't know how deep it is, but looks to be 12 feet or more (My pool is 9 feet deep). With my luck if I tried to measure it I would just end up dropping the thing I was using to measure it with down in the pit. LOL!

The sump pump evacuates the water through a backwash hose to the street which is about 140' away. My filter also dumps the waste/backwash into the sump pit.

Edit: I never turn the power off to this, even in the winter. The water level is far below the frost line. It runs whenever it needs to much like a sump pump in the basement that many houses have around here.
