Motorhome drain smells? Tips for cleaning and odor removal

As an enthusiastic camper, you know how important a working drain system is in your motorhome. Unfortunately, unpleasant odors can develop here too when the drain starts to smell. The good news: with a few simple measures you can clean the drain effectively and get rid of the odor. In this post we’ll show you how to clean your motorhome drain and bring back a fresh atmosphere.

Motorhome drains: design and typical problems

The drain setup in a motorhome is similar to what you find in houses or apartments. There is also an odor trap (the siphon) that prevents unpleasant smells from rising into the vehicle. However, motorhome drain pipes are often smaller and more prone to clogs.

There are several reasons why a motorhome drain can smell. Most often it’s dirt such as hair, soap residue, or food scraps that builds up inside the pipe and over time forms a foul-smelling slime. This slime is an ideal breeding ground for bacteria, which trigger fermentation and decay processes — causing unpleasant odors.

Cleaning your motorhome drain the right way

To clean the drain effectively and remove unpleasant odors, follow these steps:

1. Use drain strainers: Prevent dirt from entering the drain by using strainers. They catch coarse debris such as hair or food scraps before it can go down the drain.
2. Mechanical cleaning: If the drain is already clogged, start with a mechanical clean. Unscrew the lower pipe bend and remove visible dirt or blockages. Then flush everything thoroughly with hot water.
3. Use a microbiological drain cleaner: For stubborn deposits and strong odors, use a microbiological drain cleaner. These cleaners contain microorganisms that break down deposits with enzymes and help combat odors.
4. Preventive maintenance: To avoid future clogs and bad smells, clean your motorhome drain regularly. Use strainers and apply the dipure® microbiological drain cleaner every two weeks to prevent bacterial buildup and odor formation.
