Do sump pumps run in winter?

Firstly, it is important to note that it is normal for sump pumps to run occasionally during the winter as a bit of melted snow will accumulate in the sump pit over time. A sump pump which engages for long periods of time but isn't able to remove moisture from the sump pit can overheat or even burn out.

Should there be water in my sump pump pit?

2 Answers. The water should not be that high in the sump. It should be down to around the 2-3" level inside. First, find the float switch which should turn your pump on when the water gets deep enough (it should be a ball floating in the water somewhere, maybe under the drain pipes).
