I have a vacuflush system with a VG12VDC vacuum generator. Last year it worked fine. This year not so much. When the system is turned on the pump starts but never generates a vacuum. It is not that it is leaking down and turning on every so often. The pump turns on but never generates a vacuum.
Water does not leak out of the bowl. I just replaced 3 duckbill valves. The ones replaced actually looked pretty good. I replaced 2 on the out flow side and 1 on the inflow side. If my set up has a 4th valve I could not find it on my set up. Yes it was installed at the factory.
So, questions...
1) Where is the 4th duckbill valve?
2) Where do I go next in tracking down the leak? The hose between toilet and vacuum generator tank?? or The pump bellows?? How would you assess the bellows?
Thanks,
John
