Black Bits from Toilet Flush
Some time ago I am sure that I read on the forum a solution to a problem of 'black bits' coming into the toilet bowl from the toilet flush. At the time was not a problem to me. Now it is and the old memory is fading and cannot seem to trace the advice given through the formum search facility...forums.practicalcaravan.com
The pump might be getting blocked up with black bits. These form if using too much of the pink flush or not draining it down regularly. Try flushing some puriclean or milton through it.Anybody got any idea's about the flush on a cassette toilet flushing slow and is there anything i can put into the water to clean to the pump out any idea's would be gratefull
