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.
Items you will need
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.
