A Natural Solution for Odour-Free Grey Water Tanks

Grey water tanks collect much more than water. Every time you use the kitchen sink, bathroom basin or shower, fats, oils, grease, food residue, soap and body oils can enter the wastewater system.

Over time, this organic material can coat tanks, drains and pipework, creating unpleasant odours and stubborn build-up — particularly when a caravan, motorhome or RV sits unused between trips.

ProPower Grey Water works differently. Instead of simply covering unpleasant smells with fragrance, it introduces a proprietary blend of naturally occurring probiotic microbes that help break down organic waste and manage odours at their source.

Why grey water tanks smell

Grey water from sinks, showers and basins carries small amounts of food, fats, oils, soap, skin cells and other organic material into your wastewater system.

As this material collects inside drains, pipework and the holding tank, it can form a layer of residue that provides an ideal environment for odour-producing microorganisms.

The problem can become particularly noticeable when an RV or caravan is stored between trips. Residual wastewater and organic matter remain in the system, and the smell can quickly become apparent when you next open the door.

Simply masking that smell doesn’t remove what is causing it.

How ProPower Grey Water works

Grey water smells are a sign that something is happening inside your wastewater system.

ProPower Grey Water contains a proprietary blend of probiotic microbes. Once introduced through your sinks and drains, these beneficial microbes travel into the pipework and holding tank where they help consume organic material.

This helps manage the fats, oils, grease and other organic residues responsible for sludge and unpleasant odours.

Rather than relying on harsh chemicals or synthetic fragrances, ProPower helps establish a more beneficial microbial environment throughout the grey water system.

Frequently Asked Questions

What is grey water and why does it matter?

Grey water is wastewater from showers, bathroom basins and kitchen sinks. Unlike black water, it does not contain toilet waste, but it can still contain food particles, fats, oils, soap, body oils and other organic material that can create smells and build-up.

Why does my caravan or RV grey water tank smell?

Organic residue entering through sinks and showers can accumulate inside drains, pipes and the holding tank. As this material breaks down, it can create strong and unpleasant odours. The problem can become particularly noticeable when wastewater remains in the system while an RV is stored.

Does ProPower just cover up grey water smells?

No. ProPower Grey Water is designed to help manage the organic material responsible for odours rather than simply covering the smell with synthetic fragrance.

Where do I add ProPower Grey Water?

ProPower can be added through sinks and drains so it travels through the pipework before reaching the grey water tank. This allows the treatment to work throughout the wastewater system rather than only inside the tank.

Does ProPower help clean the pipes as well as the tank?

Yes. Adding ProPower through sinks and drains allows the probiotic treatment to pass through wastewater pipework on its way to the holding tank, helping manage organic residue throughout the system.

Can ProPower help with fats, oils and grease?

Yes. Fats, oils and grease are common contributors to grey water build-up. ProPower’s probiotic microbes help break down organic material within the wastewater system.

Can I use bleach or strong chemicals with ProPower?

Avoid bleach and heavily caustic cleaning products in the wastewater system. These products can kill or reduce the beneficial microbes that ProPower relies on to work.

Is ProPower Grey Water suitable for caravans and motorhomes?

Yes. ProPower Grey Water is designed for grey wastewater systems found in caravans, motorhomes, RVs and other applications using grey water holding tanks.

How often should I use ProPower Grey Water?

For best results, use ProPower as part of your regular wastewater maintenance routine. Follow the recommended dosing instructions for your tank and system size.

Can I use it if my grey water tank already smells?

Yes. ProPower can be used to treat an existing grey water problem as well as part of ongoing preventative maintenance. Systems with significant existing build-up may require continued treatment while the accumulated organic material is broken down.
