We just went through a bad patch of rain and my sump pump will not stop pumping. Compounding this problem is the fact that no water is being pump outside. It's being recycled back into the sump. Fortunately, we didn't flood, but I am wondering what the problem could be. I checked the impeller for blockages (none), the lift pipes for blockages (none), the check valves (looked good) and cleaned the pump off (no dice).

I bought a new pump today, installed it, and still have the same problem. The water is still being recycled through and nothing is going outside.

Any ideas?[xx(]
