Has anyone changed all four duckbills on a Vacuflush Vacuum Generator? Not a Vacuflush Vacuum pump with a separate vacuum tank. I am concerned about how to change the two duckbills that are between the pump (which is bolted on top of the tank itself) and the tank without disturbing the seal on the tank.
The two away from the tank can be changed without unbolting the pump but I don't think the other two can be changed without removing the pump.
