In the winter, it’s not uncommon for RV sewer hoses to freeze. This can be a huge problem, as a frozen sewer hose can prevent you from dumping your tanks. If you find yourself in this situation, there are a few things you can do to try to unfreeze your sewer hose.
Ways to Unfreeze a Frozen RV Sewer Hose
If your RV sewer hose freezes, you can use a blow dryer to thaw it out
Turn the blow dryer on to the highest setting and aim it at the frozen sewer hose. Start at one end of the hose and work your way down. Once you have thawed out the entire hose, you should be able to use it as normal.
If you don’t have a blow dryer, you can also try using a space heater. Place the space heater next to the frozen sewer hose and turn it on to high. Again, start at one end of the hose and work your way down until the entire thing is thawed out.
Pour hot water over the frozen hose to melt the ice and free it up
If you have a tank with hot water in it, you can use that. If not, heat up some water on the stove and pour it over the frozen hose. Start at the top of the hose and work your way down so that the entire thing has a chance to thaw.
Use a plumbing snake to clear any clogs that may have formed in the hose
If your sewer hose is frozen because of a clog, you may be able to clear the clog with a plumbing snake. Insert the snake into the hose and turn it until you feel resistance. The resistance should be the clog breaking up.
If you can’t clear the clog with a snake, you may need to use a plunger. Put the plunger over the end of the hose and pump it up and down until the clog breaks free. You may need to do this several times before the clog finally clears.
Once the clog is cleared, flush out your sewer hose with some water to make sure everything is clear.
Pour vinegar down the sewer drain to help dissolve any built-up sludge or grease
If your sewer hose is frozen because of a build-up of sludge or grease, you can try pouring vinegar down the drain. The vinegar will help to break down the sludge and grease, making it easier for the water to flow through.
To do this, mix equal parts vinegar and water in a pot and heat it up on the stove. Once it’s hot, pour it down the sewer drain. Let it sit for a few minutes before flushing with some hot water.
Use a de-icer on the sewer hose to help melt any ice that has formed
There are special de-icers that you can buy that are designed to help melt ice. These de-icers can be found at most hardware stores.
To use a de-icer, simply follow the instructions on the package. Typically, you will need to pour the de-icer onto the sewer hose and then let it sit for a few minutes.
