How to prevent and fix a leaking cassette toilet
With the caravanning season in full swing, you want to avoid a leaking cassette toilet at all costs. A Thetford cassette toilet is a convenient and reliable RVing essential. However, leaks can happen. But fear not! These straightforward and highly effective tips will help you to keep your caravan or motorhome toilet in perfect condition, ensuring you can continue your travel journey worry-free.
2. Recognise and repair faulty water supply connections
In some cases, the water connections to the cassette toilet are faulty. Check the water supply hose and connections for any signs of leaks, loose fittings, or cracks. Also, ensure the hose is connected properly to the water source and the toilet. If you notice any issues, tighten the connections or contact a local Thetford service centre.
4. Improper cleaning and maintenance
Not maintaining the cassette toilet is one of the main reasons for leakages. By maintaining the toilet using Thetford’s Duo Tank Cleaner Concentrated and Seal Lubricant Spray, you’re not just preventing leaks but also prolonging your caravan toilet’s lifespan. Duo Tank Cleaner Concentrated is a periodical maintenance product that removes limescale, encrusting and grease from the waste-holding and greywater tanks. Apply this product 2-3 times per season to keep your toilet in top shape. In addition, regularly using Seal Lubricant spray on the rubber parts of the toilet helps repel dirt and dust and prevents rubber seals from cracking.
It’s also essential to take good care of the motorhome toilet by using dedicated toilet care products for the waste-holding tank and the cassette toilet itself. Most household cleaning products are abrasive to the rubber compartments of the toilets, including the lip seal, and can lead to leakages. Thetford additives prevent odour formation and treat the waste in the tank most effectively without harming the material. Thetford Bathroom Cleaner and Toilet Bowl Cleaner are intended to safely clean the toilet.
5. Mind the fill levels
Overfilling the cassette can cause leaks, as the excess fluid has nowhere to go but out. Therefore, make sure to empty the waste-holding tank before it reaches capacity. Specific Thetford cassette toilet models have a level indicator that tells you when to empty the toilet. When you fill the flush water tank (if applicable) and waste-holding tank with water, ensure that you adhere to the instructions and don’t overfill the tanks. Consult the user manual of Thetford’s cassette toilets (also available in digital format online) for the correct water levels. Also, adhere to the instructions on the labels of toilet care products when adding a toilet additive, to avoid overfilling.
6. Store the cassette toilet in the correct way
If you plan not to use the cassette toilet for a longer period, empty the water tanks to limit limescale build-up and avoid frost damage in colder conditions. After draining, press the flush button a few times to clear the pump of residual water and leave the blade open to ventilate the tank. Use Thetford’s Cassette Carry Bag to store the waste-holding tank, protecting it from dust, dirt, and moisture. This helps prolong the lifespan of the waste-holding tank and its components.
