I have a VacuFlush head system on my 07 320, the pump would run constantly since the midway part of my last trip, so I purchased new duckbills and bellows and o-rings. Replaced all, and initially, same issue, but realized I missed an o-ring, fixed that, and now it builds up a vacuum, but then loses it 10 seconds later, pump runs for 5 seconds, then 10 seconds later starts again. So, to determine if it was a problem from the hose connection to the toilet, I removed the hose from the toilet, (important note, I had removed it as part of this process anyway, although it did not need to be removed), when I placed my hand over the hole and turned on the pump, it stopped running 60 seconds later, and stayed off for the 2 minutes until I removed my hand (no hickey! Actually, used a thick rubber glove, so the glove expanded, not me). So, I know the vacuum tank is perfect, and my installation of the bellows and duckbills were correct. The issue must be between the connection to the vacuum tank, and the toilet. Note, the toilet has water and did not leak at all, remained constant volume. My first guess is the connection to the tank, my theory is I did not do it right, or the o ring is bad. My understanding is I should simply hand tighten the nut (connecting the hose from the toilet to the tank) and then turn it 1/2 turn with a wrench, which is what I did. Aside from checking the o ring, is there anything else that I should do? Use any type of tape or sealant, follow a different procedure? As always, thanks for your help...
If it is not the connection, then could the hose be bad and allowing air to come through it? It does not seem to be the toilet, since it holds water, so the seal at the top of the bowl seems fine, but is there another way for air to get in below the flap/ball that holds the water?
