Question

My Thetford C2 wont flush the pump can be heard running but no water is passed to the bowl. Any ideas, could it be the sanitary fluid has solidified and blocked the pump supply tube. regards Tom bartram

Answer

It is unlikely that the sanitary fluid has solidified. It could be that the pump rotor has become detached which results in the pump running but not pumping. It may be possible to lift the pump from the tank and place into some clean water to see if it will pump. The pump is situated underneath the toilet roll holder (which lifts out) and is held in place by a single cross headed screw.
