I have a sump in a dike with sump pump installed.  Since it does not  automatically turn on, the pump will get partially submerged on a regular basis.  In the winter the water could freeze around it.  I would like to prevent that.

Since the discharge pipe is heat traced, I would like to just extend some self regulating heat trace down around the pump.  Is there heat trace that can be mounted in wet/submerged area?

I was looking at de-icing roof gutter heat trace.  It obviously gets wet normally.  Is it OK to have this submerged (max depth ~2').  Any junctions would be out of potential wet area.  I understand this cable has extra sheathing on it for water/weather protection.

Thanks,

Marty
