Thetford Aqua Magic IV handflush in my Lance 810. Leaking clear water out the bottom where it joins the shower floor. Only leaks when the hand flush is used so it must be a leak in the line between the flush handle and where the water enters the bowl on the other side. Can the top of these toilet be taken apart? Or how do you remove the toilet?

Could be the gasket around the top of the hand pump, or just loose ..hope this helps

put a little dishwasher detergent in the holding water tank of tolit then pump bubbles will apear where leak is
