Valves and Flush Components
Keep your Dometic MasterFlush 7640 pedal-operated macerator toilet flushing reliably with genuine water valves and flush components. A worn water valve is a common cause of a 7640 that won't add water, runs continuously, or floods the bowl — and replacing it is a straightforward, affordable fix. Shop the genuine replacement water valve and flush components built specifically for the discontinued Dometic MasterFlush 7640 toilet, so you can restore full "Normal" and "Dry Bowl" flush function in your motorhome or fifth wheel.
