Unclogging a Shower Drain in an RV

A clogged drain can be caused by hair, small objects or even paper. Strong chemicals can damage RV pipes, so it is best to try to unclog the drain manually first. If that does not work, a simple solution of vinegar and baking soda should do the trick.


  1. Pour 1/2 cup of vinegar and 1/2 cup of baking soda down the shower drain and cover the drain with a glass baking dish for at least two hours (recommended during the night) . This mixture should loosen the obstruction. Rinse the shower drain with hot water after the elapsed time to determine if the blockage is still present. If it is still there, move on to the next stage.
  2. Remove the drain by prying it out of place with a Phillips screwdriver. Use a flashlight to determine if there are any accessible obstructions (i.e., hair balls) that can be reached with a wire. If the obstruction can be seen, use the cable to pry it out of place and bring it to the surface.
  3. Rub Vaseline around the edges of the plunger and place it around the shower drain. Vaseline acts as an adhesive and ensures that the plunger will have maximum suction. Push down and pull the plunger up for approximately 15 to 20 minutes to try to bring the blockage to the surface. If the obstruction does not come immediately to the surface, try to place a cable to the obstruction and pull it through the top of the leak.
