Shower P Trap Frozen

– If this is a recurring problem, you can wrap the P-trap (from underneath the house or through an access panel) with an electric heat tape designed for pipes. Plug it in only while thawing.

If the blockage is ice, chemical drain cleaner will simply pool on top of it. When it eventually thaws, you’ll have a highly corrosive liquid surging through your pipes—dangerous for you and potentially damaging to old metal plumbing. shower p trap frozen
