Does anyone have some ideas about what I can do about my vacuum toilet when spare parts are no longer available. The vacuum only holds for 20 seconds.

Oh that has gota suck...but not nearly as much as it should.

Sorry I cant let a straight line like that pass.

depending on what they are, you may.

Find that some parts are generic...like O rings and other fittings.

Find that parts from another model or brand fit or can be made to fit.

make the parts from first principles.

What in partucular do you need.

cheers

What exactly do they say is wrong with your docking station.

You could talk to these people about installing one of these. depends on room and whether you can handle having a pump out system.

I have found that the usual problem is leaks around the small 13mm O ring on the base station. With the constant pushing in of the cassette it starts to bend the front feet of the base station and it leans back at an angle. When this happens the cassette no longer goes far enough in to seal around the O ring. If this is the case you can pack it up at the back to stand it up.

Sorry no idea where to get it done. I only ever do all work on my rig myself. To see if this is the reason just have a look and see if the cassette is going all the way over the small spigot.
By the way if anybody is buying O rings,all except the double can be sourced from CBC bearings for cents each instead of the $10.00 plus each as dometic spares. This includes using a normal round O ring in the screw lid instead of paying $30 plus for a new lid from dometic.

pj p ....you can do the job yourself as there is only 3 "o"rings to replace in the base station .... just make sure you put plenty of silicon grease on them ..... also clean the half ball seal and grease that .... just look at the parts diagram on the Caravan Plus web site

Thanks for help. Have replaced the 3 0 rings . Will look up CBC next time. Still no better.
How can I check what is wrong with docking station? Was told the small spigot was sucking when it should not be.
Oh how I miss my handy man Husband who up and died on me!
Is the half ball seal in the toilet bowl.
I clean that with a piece of card. Would you grease that too?

After going through all sorts of fixes, over a 5 year time frame, (this was from both the supplier and repair centre) my brother chucked it last year and fitted a Dometic flush toilet. It took a bit of work but as they live in the van full time, the new one has made for much happier living now. Cheers,Bob.

Have you tried Caravan Plus they have some parts still available. Sounds like you need to replace all the "O" rings and use plenty of silicon grease on them ..... don't forget to do the half ball as well

We have a vacuum toilet, van is now 7 years old and only now having issues - we lived in it full time for 9 months and the hard water on the Limestone Coast had a detrimental effect on seals and ceramic parts. Replacement of O rings on a regular basis is a definite. CaravanPlus is your friend - parts are available for replacement but my husband is a very handy chappie - otherwise it would have cost us a fortune to pay for someone to do the repairs. I think his consideration is that should more repairs be required in the future, a replacement Dometic or Theford toilet will be the way to go.
