Re: Sump Pump - Discharge riser freezing

Back up pumps should have their own discharge piping. We see why in this thread. If the discharge is blocked or frozen the back up pump can take over and discharge through it's own piping. Unless you have bad access, installing back up piping shouldn't be too hard, and could eliminate the need for checks.
