We have a condensate furnace and a small sump pump located at the base that pushes water up (from a collection pan on the basement floor) and out of the house. The tygon tubing line, as it exits the basement, keeps freezing (as it is cold in Ct winters). Since it freezes, the water can not drain and the pan overflows into the basement.

I have two questions. How am I going to prevent this from continuing to freeze all winter?

Why is my furnace removing moisture from the air? We run humidifiers all winter because the air gets so dry. Sholdn't my furnace help regulate the humidity to a comfortable level in winter? What can I do? (ok more that 2 questions)

Thanks for your time.
