Re: Sump Pump - Discharge riser freezing
For the top of the riser to go outside, is that pitched at all to go outside? If not, it may be that water is accumulating at each pump, freezing, then repeating. And over time, eventually plugging. If it's not the vertical portion that's freezing pitching the horizontal section down may help.
Another idea is to go higher with the vertical pipe inside, put two 90s together to bring it back down and then out. This introduces more distance between where the water sits when the pump is not on and where the cold pipe is where water's freezing. Or instead of the two 90s, put a 90 then a 45 and angle it outside. You want to prevent any water from sitting for any period where it's freezing.
