Campervan Water Tank Cleaning | If you’re hitting the road in your campervan, motorhome or converted van, clean water is essential to your comfort, hygiene and health. Over time, water tanks in campervans can collect bacteria, algae, sediment and scale, which may affect the taste and safety of your water supply.
At Green Water, we offer campervan water tank cleaning services across the UK, helping owners maintain safe, fresh water systems all year round.
Why Clean Your Campervan Water Tank?
Whether you use your campervan for weekend trips or extended adventures, keeping your water tank clean is vital. Drinking water stored in tanks can quickly become unsafe if the system is not regularly flushed and disinfected.
Common issues in poorly maintained campervan tanks include:
- Bacteria or algae build-up
- Unpleasant tastes or smells
- Biofilm on the inside of the tank
- Limescale deposits from hard water
- Risk of illness from contaminated water
Regular cleaning not only protects your health, but it also extends the life of your water system and keeps everything running smoothly.
How Often Should Campervan Water Tanks Be Cleaned?
At Green Water, we recommend cleaning your campervan water tank:
- Before the first use of the season
- If the van has been in storage or unused for some time
- If the water smells, tastes odd or looks discoloured
- Every 6 to 12 months as part of a regular maintenance routine
The frequency of cleaning can also depend on how often you use your van, how long water is stored, and whether you refill from a mains supply or campsites with varying water quality.
Our Campervan Water Tank Cleaning Process
We provide a safe and effective deep cleaning service using approved, non-toxic chemicals designed for portable water systems. Our process includes:
- System Drain Down – Safely emptying the fresh and grey water tanks
- Internal Rinse and Agitation – Loosening and removing scale, algae and debris
- Disinfection – Using safe cleaning agents to kill bacteria and remove odours
- Flush and Refill – Ensuring the tank is thoroughly rinsed and safe to use
- Inspection – Checking for signs of damage, contamination or wear
We can also advise on filters, water quality testing and maintenance tips to keep your system clean on the go.
Do You Need Professional Help?
While some campervan owners choose to clean their tanks themselves, professional servicing can ensure a more thorough and hygienic result, especially if:
- You’ve just bought a second-hand van
- The water has not been used for a while
- You’re unsure about using chemicals safely
- You want peace of mind before a long journey
At Green Water, we handle the process from start to finish, saving you time and ensuring your water system is fresh, safe and ready to use.
