THETFORD C200 CWE Caravan Toilet Flushes intermitantly?
There is water in the header tank and the pump can be heard running, but not flushing for various periods of time. There appears to be no consistancy in its failure to flush, as it will work on checking before travelling and on site, then another time it won't work on site but on checking on return to base it flushes again ok. Having removed the top curved switch cover the tank looks quite clean. Any ideas?
