Vacuum is between the pump and the head. Start with the seals on the toilet and a new cartridge in the flush pedal. That has two o-rings that can leak over time. If that doesn’t do it. Down to the duck bills. And if that doesn’t work, it may be the pressure switch , but with your symptoms I think the first things I mentioned will solve your problem. Good luck.Vacuflush question. Where is the actual vacuum pressure in the system? I ask because I’m having issues with the master head pump running - sometimes continuously and sometimes it turns off and back on. And I notice that I don’t get the strong “whoosh” when flushing that head like I do in the guest head. There’s a bit of a water leak down in the master, too. I have the toilet seals and plan on replacing them this weekend. And I ordered the seals for the other head and the duck bills for the whole system (8). I will do the whole job. But for now, I want to do the minimum necessary to fix the issue and not impact my upcoming trips.
I ask my question about where the pressure is because I’m thinking that if the pressure is between pump and toilet, then the toilet seals might solve the whole problem. But if the presssue is behind the pump (on the black water tank side) then I’m going to have to do duck bulls ASAP. Obviously, it could be both, too.
So... is my thought that it might just be the seals valid, or is it just wishful thinking?
Thanks
