Another Vacuflush thread

My vacuflush is not creating a vacuum.


Here is my process so far.


1. Water stays in the bowl, but no vacuum when the toilet is flushed. the water runs slowly into the vacuum tank and the pump pushes it out, but no vacuum. There is no hissing at the toilet.


2. The pump runs all the time, until I turn it off at the breaker.


3. I replaced both the duckbill valves on the outlet hose, as they are easiest to get to. The toilet created a vacuum and flushed fine about 6 times, then stopped working and is now behaving exactly as described above. No pressure at the toilet, pump runs all the time, water stays in bowl.


4. I replaced the other two duckbill valves, which on my unit are inside the vacuum tank. Lots of sludge built up in there. No improvement.


5. I replaced the bellows. No improvement.


I think I've got an air leak somewhere in the vacuum tank, but I don't have a tester and can't get one until Monday, I'm on the boat all weekend. I'm out of spare parts, I guess I should have bought an O ring kit, but didn't think about it.



Any advice?
