Dear JES: My Sump Pump Line is Frozen!

Dear JES: 

It's been really cold up here and my sump pump discharge line has frozen. I have an older sump pump and the line just extends past my foundation. 

Now the water isn't draining outside like it's supposed to and I'm afraid that it's going to backup into my basement. How do I fix this?

Hi Aaron,

Thanks for writing us. Frozen discharge lines can be fixed and avoided in the future. Here are a few suggestions to help defrost your discharge line. Remember it's always best to consult with an expert before you try to defrost the pipe yourself.
  • Pour hot water down the pipe. That should loosen up the ice enough to get it flowing through the discharge line. 
  • If you're unable to pour hot water down the pipe due to the angle, snake a thick rubber tube into the pipe until it reaches the blockage. Pour the hot water down the pipe to melt it.

Once your discharge line is defrosted, it's a good idea to contact your local basement waterproofing expert. They should be able to set you up with a discharge line cover, IceGuard, which will prevent the pipes from freezing in the future.
