How to Unclog a Drain in an RV


As with the bathtub or sink drain in any home, dirt, food, hair and residue gets rinsed down an RV drain which then creates a clog that must be removed. When you clear an RV drain, you must use safe, mild ingredients that will not damage the plumbing system in the RV. Luckily, there is a safe enzyme cleaner that you can make yourself and use as needed to keep your RV drains clear.

Things You'll Need

  • Baking soda
  • Vinegar
  • Hot water
  • Pipe snake
  • Pour 1/2 cup baking soda down the drain.

  • Drizzle 1/2 cup vinegar over the baking soda, and immediately cover the drain. The two ingredients will react by creating a foam which will work its way down the drain and break up the elements causing the clog. The combination will also deodorize the drain. Let it sit for one hour.

  • Pour 1 gallon of hot water down the drain to wash away the broken up residue.

  • Push a pipe snake down the drain to break up any remaining residue, if the drain is still not emptying properly.
