Question

Hi, I have a Thetford C250 flush toliet and water has started dribbling out of the little inlet pipe at the top of the bowl into the main bowl even when it is not being flushed. How do I fix this?

Answer

I imagine you have the C250CS toilet which draws its flush water from the caravan water supply. When you operate the button to flush the toilet it opens a magnet valve to allow water to reach the bowl. When you release the button the magnet valve should close restricting the water flow. If the magnet valve is faulty or if some dirt has been lodged in the valve then the valve will not close fully and you will find water dribbling into the bowl. The magnet valve is our part 229433.\r\n\r\nRepair instructions can be found at http://www.thetford-europe.com/en/service/repair-instructions.aspx
