How to Stop Sump Pump Discharge Lines from Freezing
Last winter, our basement sump pump discharge line froze right where the PVC pipe exists the foundation wall outside. The pump kept running against the ice blockage and almost burned out the motor before I unplugged it.

Discharge lines freeze when water remains standing in the exterior pipe instead of draining completely away after a cycle. A proper installation includes a continuous downward slope on the outdoor piping, along with a specialized freeze-guard relief fitting right outside the rim joist.
