Great information, thanks for sharing.

I have replaced the duck bills 2 times. There is always water in the bowl and it leaks down so quickly, maybe 2 min. Between pump ups. I dont think the shaft at the foot pedal can be leaking you would hear air sucking right?

The best thing you can do with a vacuflush toilet is rip it out and replace with an electric one, I’ve had a vacuflush for 10 years and live aboard, I know the system backwards and some, with the cost of parts now it’s just not worth replacing them for me, as a live aboard I wear everything out in under 12 months

My vacuflush wouldn't stop pumping. Even with new everything including the switch. Finally I discovered that the waste tank vent was clogged. The tank was becoming pressurized and the pump could not make enouh vacuum. Once cleared it worked fine. Now the ball doesn't move with the pedal. Next I'll pull it apart. If its a major problem we're going to a composting toilet.

Thank you for sharing this great information. Do you have any information on the pedal seal. I looked for it online and cannot find that seal. If you have any information you could share, I would greatly appreciate it. Thanks!

Also the y valve for overboard or holding tank discharge. One of my hoses going into that valve was leaking at the valve.

Good explanation. I don’t have one but it seems simple.

Don’t cheap out of the duck valves, the Amazon ones last about 3-4 months before they harden

The ball went to the other side and is in the open position. Maybe it’s has to do with spring disconnected from foot pedal. What’s ur diagnosis? Thanks

Ok, so what do you make of this... push the pedal to the floor to flush and the ball valve (flap, valve, not sure what you call that round ball flap) does not move... so no flush? Thoughts?

no spring action in foot pedal. have to fill water by lifting foot pedal

Good video. Mine cycles every 30 minutes or so. I replaced the duck bills and the seal at the pedal, same result.

Great video Captain! I have a 2002 formula 27Pc, docked at Bear Lake Marina Utah, I replaced the whole pump, Jason a nice guy in Huntington L.I., N.Y, where I use to live! Has all the parts you need! I found the ball seal gets partials of dirt in it and the seal will leak, gloved hand and use your finger to clean it out! Also if you cannot find the liquid seal, use silicon tire shine to loon the seal for winter storage . Chow JohnBoyUtah, Brenda’ hubbie!🇺🇸😎🚤🚤🚤🚤🚤🚤🚤
