Once the crisis is averted, take steps to prevent it from happening again:
If the ice is extremely hard and thick, heat may take too long. You can break the ice mechanically. how to fix a frozen shower drain
If your shower or tub is full of cold water, use a bucket or a like a Shop-Vac to clear it out. Removing the cold water allows your heat source (like hot water) to reach the ice blockage directly rather than being cooled down by the standing pool. 3. The Hot Water and Salt Method This is the most common and effective DIY fix. Boil Water: Boil 2–3 gallons of water. Once the crisis is averted, take steps to
A frozen shower drain usually occurs in the , the U-shaped pipe beneath the floor where water stands to block sewer gases. To fix it, you must thaw the ice blockage using safe, indirect heat or chemical melting agents. Direct Action: How to Thaw the Drain Removing the cold water allows your heat source
This is the most effective method for a standard shower drain where the freeze is likely in the P-trap (the U-shaped pipe underneath the drain).
Once you see a trickle of drainage, boil 2 quarts of water and add ½ cup of rock salt or table salt. Carefully pour it down the drain. The salt lowers the freezing point of water and the heat melts the remaining ice. Pour slowly to avoid splashing back up.
Pour ½ cup of hot (not boiling) water down the drain. If it sits there without draining, the blockage is likely ice. If it drains slowly, you may have a hair clog, not ice.
