I just went through the exact same thing. Same symptoms. I threw so many parts at it I gave up and took it in. Long story short, they determined my hose is getting old and weak and it’s not holding shape well and hence loses vacuum. They adjusted the vacuum from 10 pounds to 9 pounds and it supposedly fixed it for now and bought another few years. (I have not picked the boat up yet to confirm)I will replace my hose this winter. Providing its working ok now.
Exactly what hose are you talking about? The one that runs from the toilet to the vacuum pump?
Thanks
