These guys have a very good video on how to work on the Vacuflush system. They also have very good customer service and the parts you’ll need.

Good luck!

Like many others my bellows ruptured on year 6 of ownership. Thankfully I had kept a rebuild kit on hand but the cleanup at the campground was not fun. After I got home I ordered not only another rebuild kit but a backup motor replacement just in case that fails. The vacuflush system works well when it works but it can ruin a trip if it breaks while traveling

I’m $5000 in and getting a new vacuflush system installed. Keeping the old one and having it rebuilt for whoever is unlucky enough to buy this rig. At least they’ll be forewarned. Can’t wait to sell it and buy something that was made by a company that actually understands what life in an rv is like.

2016 Bounder 33c & having to repair vacuflush system 1st time. Was slow to build vacuum. Ordered all parts fm Amazon. Bellows kit Dometic 385230980, O-rings Dometic 385310151, & 2ea 1 1/2” duck valves Dometic 385310076. Get the Dometic parts, off brands have very bad reviews.

I replaced the bowl seal gaskets as well. Might be worth changing those out while you are at it.

I don’t understand the $5000.00 comment unless it is all brand new and installed by RV Tech at a high cost. Replacement parts are roughly $200.00 and DIY at ~3hours of your time.

I had to buy a brand new pump which cost $2300 plus $500 labour. Before that I had to buy a new toilet because it wasn’t holding water anymore. They told me it was cheaper to change the toilet than to install a new ball valve. The cost for the vacuflush toilet was $972 plus another $400 in labour. Convert that to Canadian funds and I’m looking at $6000 for a toilet which still doesn’t work right. It stopped working after 2 flushes. He adjusted it today but is it normal for the pump to run for 5 minutes after every flush. I’ve pretty mush given up on the thing

We avoid using our vacuum toilet system, we use the gravity feed toilet 98% of the time, put TP in the waste basket, use lots of water.

I am so glad I escaped all this. Soon after I bought my first motor home which was a 24' class C in 2013 I decided I wanted another M H, only a bit larger with more room around the bed in the bedroom so I started doing research on Class A units. I found this forum but even though I didn't join until 2015 I lurked and learned. I came up with a "Don't want" list to shop with which was longer than the "Had to have" list. After reading about all the horror stories about problems people were having with the "Vacu-Flush" system this one made the top of my "Don't want" list.
I guess this is the reason I ended up with a coach at the bottom of the pecking order but I'm using and enjoying it instead of working on or tinkering with it constantly.

Just repaired vacuflush system today total costs for parts $200 fm Amazon all Dometic parts. Took about 3 hrs start gathering stuff, running 3 g water through toilet, to final test & putting everything away. Hard place to excess, but not bad. Replaced all 4 duck valves, & they were bad, replaced bellows even though it looked good (6 1/2 yrs old), and replaced seals. Now vacuum pump runs 1/2 time as it did before. Still haven’t replaced toilet seal yet. That’s next. I bought off band & I’m hearing to just buy a dometic seal. As for problems with vacuflush system, all RV’s have problems, you can’t get away from fixing something almost every time you go out. Every brand whether it’s 500K to 20K RV. $5k for vacuflush system repair is extreme. I would never go back to that repair place.
