Re: Sump Pump - Discharge riser freezing Hook up a hose on a slow trickle into the sump pit so the pump cycles at least a couple times an hour even during the winter. Flushing fresh water through there regularly 24x7 should keep things thawed nicely, I would think. At the very least I'd try this before dicking around drilling holes in pipes.
