Why Do My Caravan Sinks Smell?

Few things spoil a trip like a kitchen sink that smells like a drain. Caravan and RV sinks are particularly prone to it, and it’s not because you’re doing anything wrong. It’s down to how a mobile grey water system works.

Where the smell comes from

Kitchen sinks send food residue, cooking fat, grease and detergent into the grey water lines. Bathroom basins add toothpaste, soap and hair. Unlike a house, where waste flows quickly to the sewer, a caravan’s waste water sits in short runs of pipe and in the grey water tank. That trapped material becomes food for odour-producing bacteria, and the smell comes back up through the plughole.

Common signs

A rotten egg or sour smell from the sink, especially in warm weather.
Slow draining as grease builds up in the pipe.
The smell getting worse after travelling, when traps empty on bumpy roads.

Treat the pipes, not just the plughole

Strainers and deodorising tablets help a little, but they don’t touch the build-up inside the pipes. ProPower Grey Water Tank Treatment uses beneficial microbes to digest food residue, grease and soap scum in the pipework and tank. It consumes the odour and breaks down the sludge rather than covering it.

How to use it

Wipe excess grease from pans before washing up.
Pour a dose of ProPower Grey Water Tank Treatment, mixed with water, down each sink.
Leave it to sit in the lines overnight or between trips.
Re-dose after you empty the grey water tank.

Because ProPower is 100% natural, it’s intended for use in wastewater systems; ProPower is Septic Safe.
