Probably the joker valve needs changing - about £7 and an easy job!
The lavac doesn't have that type of pump, but has one similar to a manual bilge pump, (diaphragm, I think).

My previous boat had a Lavac and had a printed sign on the bulkhead giving instructions for use. This sign was probably included when the toilet was originally purchased, and a copy can probably still be obtained from the manufacturer. It would be very useful if you regularly have guests on board.
