Above-Ground Pool Cover Pump

I'm not sure the gallons per hour are up to what was advertised, but it works fine. It produces a steady flow through a 50 foot 5/8" hose that was not neatly piled and the water came out at about half the rate that I could get water to come out of the hose hooked up to my city water connection. It would provide even better pressure if sitting on top of a pool cover as it's designed for. Then gravity would be helping it instead of working against it. It doesn't turn off automatically. The filter with a plastic box can be replaced, but the filter is not easily removable from the plastic box. If I applied any more pressure to the plastic screw holding it in place I think I would break it.
