Dometic Vacuflush Question
Just got a new Bounder that has the Dometic VacuFlush we are on the shakedown cruse now. Last night after the flush as it is doing its thing the last thing was a knocking sound. Sounded just like some...

Tell your wife to do her business then hold the foot pedal down while counting to three then slide or take her foot off the pedal quickly. This will allow enough water in for the flush. If you have low pressure or are using the water pump, count to five.
Having completely disassembled the vacuum pump, I can tell you there is nothing that would 'knock' unless the motor is loose and banging against something else. However, at least in ours, we occasionally get a 'knock' when not enough water is used. It seems to be due to the acoustics of the space rather than the pump itself. Easiest way to check is to watch it when someone flushes.
