Cleaning a grey water tank in your caravan is just as important as cleaning the waste tank, as it helps prevent unpleasant odors, blockages, and bacterial buildup. The grey water tank collects wastewater from sinks, showers, and other non-toilet sources, so it can accumulate soap, food particles, oils, and grease over time. Here's a detailed guide to help you clean it properly:
What You’ll Need:
Rubber gloves
Face mask (optional)
Freshwater hose or access to water
A caravan grey water tank cleaning solution or mild disinfectant
Tank cleaning wand or special flushing device (if available)
A container or bucket (optional, for additional cleaning)
A waste disposal station for emptying the tank
Tank deodorizer (optional, for fresh scent)
Step-by-Step Process:
1. Take you grey waste tank to waste water station
As with the waste tank, make sure you take your grey water waste tank to a designated wastewater station for safe disposal of grey water. These stations are usually equipped with drainage points for grey water . Most Campsites have them
2. Put on Protective Gear
Wear rubber gloves to protect your hands from any waste residue. A face mask can help with odors, although it's not essential.
3. Locate the Grey Water Tank Outlet
Find the outlet valve for your grey water tank. It’s typically on the side or bottom of the tank. This is where you'll drain the tank. You may need to remove a cap or unscrew a cover. If using a wastemaster or similar put the tank at 45 degrees undo the top cap
4. Open the Grey Water tank waste cap
Slowly open the camp to allow the grey water to drain out into the designated waste disposal area. Let the tank empty completely.
5. Rinse the Tank with Fresh Water
Once the tank is empty, connect a hose to a freshwater supply and flush the tank. Direct the hose into the grey water inlet and let fresh water flow through. This will help wash away any soap scum, grease, or food particles left in the tank.
If you have a tank cleaning wand or a flushing system, use it to give the tank a more thorough rinse. These devices can direct water into hard-to-reach spots in the tank to help clean it out better.
6. Apply a Cleaning Solution (Optional)
If your grey water tank has built-up residues or odors, you can use a grey water tank cleaner. These cleaners are often formulated to break down grease, soap scum, and bacteria.
Follow the instructions on the cleaner’s label. Typically, you will need to add the cleaner to the tank after it’s partially rinsed, then fill the tank with water and let it sit for the recommended time. Thetford Duo is deal for this job
7. Let the Cleaner Work
Let the cleaning solution sit for a while (usually 10–30 minutes, depending on the product). This will help break down stubborn grease and grime.
Agitate the tank (if possible) by sloshing water around or by using a flushing wand to ensure the cleaner reaches all areas.
8. Rinse the Tank Again
After the cleaning solution has had time to work, rinse the tank thoroughly with fresh water. This will flush out any residues from the cleaner and any loosened dirt or grease.
Repeat the rinse process until the water running out of the tank is clear, ensuring that no soap or cleaning agent remains inside.
9. Drain and Close the Valve
Allow the tank to drain completely, ensuring no dirty water remains inside. Once the tank is fully drained and flushed, securely close the grey water tank valve.
10. Deodorize (Optional)
To keep your grey water tank smelling fresh, you can use a tank deodorizer. These are usually available in liquid or tablet form and help neutralize odors in the tank, preventing any unpleasant smells during your travels. we recommend Thetford Grey water Freshfor this application
11. Check for Clogs and Inspect the Tank
While cleaning the tank, it’s a good opportunity to check for any signs of blockages, leaks, or cracks in the tank or the plumbing system. If you notice any issues, address them promptly before they become a bigger problem.
12. Regular Maintenance
Clean your grey water tank at least once a month, or more often if you’re using it heavily (e.g., on long trips or during extended stays). Keeping it clean helps prevent the buildup of oils and soap residues, as well as the growth of bacteria that could lead to unpleasant odors.
You can also run a cleaning solution through the system regularly to keep it in top condition.
Additional Tips:
Avoid Grease and Oil: Try not to dispose of grease, cooking oils, or food scraps in your grey water tank. These substances can clog the system and create stubborn buildups that are harder to clean. Consider using a grease trap in your sink.
Use Eco-Friendly Products: Opt for biodegradable soap and cleaners that won’t harm the environment when disposed of.
Odor Prevention: If your grey water tank begins to develop strong odors, consider using odor control products designed specifically for RV or caravan systems. You can also try adding a small amount of baking soda or vinegar to help absorb smells.
Monitor Tank Fill Levels: Don’t wait until your grey water tank is full to empty it. If you’re using it regularly, try to empty it once it reaches about 2/3 full. This will help avoid clogs and buildup and over spill
By following these steps, you can keep your grey water tank clean, functional, and free from unpleasant odors. It also helps to maintain overall hygiene and prolong the lifespan of your caravan's plumbing system.
