 Water Supply Line Near Sump Crock

It's probably a water powered back-up pump. If it's on a municipal water supply and there's a power failure, the water pressure will create a pumping action.

Bill -
So what you are saying is that - providing there is a hose attached to the now empty nipple, this would act as a back up sump pump? I guess I didn't inspect this close enough. It seems like there would have to be both an input and output nipple on this pump. One to take in water from the crock and then a hose to discharge the water out from the home. Am I following you?

I could not open your picture but what you are describing is a siphon activated back up sump pump. They work very well. City water is sent though a venturi ( just like a duel line jet pump on a well ) creating negative pressure that then pulls the sump water out with the city water. The discharge is usually the same pipe that discharges the primary electric pump. Battery pump with only last a few hours, but as long as the city supply is still pressurized you are in business.

Quite common in Mark's and my world, but I don't usually find an adequate anti-siphon device installed. This would allow contamination of water supply. Your photo looks like only a "part" of the pump is still there.
