After 10 seasons on my boat my Vacuflush has started acting up. Other than a ball valve and cartridge I have done nothing to it. The generator is still making vacuum however when we flush it doesn't always come on right away. We've been able to wait and it will eventually start and I can also tap the top of the vacuum generator and it will cycle. I have ordered a new pressure switch but it looks like that switch is on the back of the pump next to my generator. My guess I will need to pull the entire vacuum pump just to get to it. I'm wondering if I should go ahead and change the duckbills while I'm at it. I guess I've just been lucky up to now. Just wondering if you all think I am on the right track.
