Recently, one of our jobs was to remove a Thetford toilet to replace corroded wiring loom. It also needed a PCB and pump as well.
Remember it is VERY important at the end of every caravan trip to drain your toilet flush water, add some plain water to the flush tank, run a little through the pump to clean the impeller, drain the flush water again and give the pump a quick blip. This will help reduce potential pump problems.
Also remember NOT to travel with flush water in the tank either.
If you have any questions about your caravan and maintenance, then please do not hesitate to get in touch with us.
