RV Toilet Valves, Seals and Repair Parts

Most RV toilet problems come down to a small number of worn parts rather than a failed toilet. A slow leak at the base usually means the floor seal needs replacing. A toilet that won't hold water in the bowl is typically a worn waste ball seal or ball and shaft assembly. When the flush pedal feels spongy or stops returning properly, the water valve is usually the cause.

The parts selection here covers the most common repairs for Dometic, Thetford, Seaflo, and Lippert toilets, including water valves, vacuum breakers, ball seal kits, floor seals, flush pedals, and seats. Check your toilet model number before ordering to confirm the right fit.
