Toilet problems

Delta18 · Guru

It sounds like you have a mechanical problem rather than lubrication. The thetford book recommends olive oil only for lube.

I would be checking that everything is lining up correctly with the cassette.

Helped a friend with a similar problem, but yours may be different.

In the waste container, my understanding is that there is a valve that lets air release if the pressure builds up, this can be blocked if you shake the container B4 empting. Friend could not remove the waste container, it seemed to be to be expanded. I removed the yellow empty cap (waste container in situ), the waste container shrunk in size and he could remove it. Your situation may be similar the container has expanded and stopped you moving the slide.

I have whole toilet out of van at the moment. Have checked alignment, have re-greased alignment rods and seal, nice and loose now. I'll wait a couple of days and work it each day, see if she seizes up again.

Welcome to the gang muzzagod, enjoy here and out in the playground.

We all have to deal with a crappy job from time to time. I use Olive Oil spray and works well for me. I have to remember not to cook the chips in that oil though.

Keep Safe on the roads and out there.

Just spoke to a friend (fellow caravanner who's been doing it for 30+ years). He had the same problem, and googled for info. Found it was a common problem with the Dometic. A new slide unit worked for a while, but the main remedy found was to lubricate the rubber seals and ( in particular ) the rods after each dump point visit. Common thoughts expressed were that sliding mechanism WOULD NOT WORK WELL after more than three days, and it is a must to at least lubricate the alignment rods every second to third day of travel.

I have a spray bottle of olive oil, srewed a tin to bottom of storage bin to hold the spray bottle. Makes a big mess is it falls over and leaks. Make sure you have pure oil, not ones called olive oil that can be up to 95% vegitable oil. Read the ingredients carefully. Cant trust a super market or dicount store. Give it all a good wash out with a nappysan equivalent. About a quarter tank of water, a cap of nappysan and shake like New Zealand. Dont forget to also shake upside down. Good luck Neil . .

We have a thetford and spread the inside mechanism with cooking oil even sprayin the bin around the slides and now and then I take of the handle that opens the trap door and spray a bit down there.

If you have the later type cassette that has a "Full" warning light DO NOT shake vigorously, you will damage the float mechanism and you will be up to your elbow inside the tank to fix it!

Spray on tyre shine is another goood lube . Silicone based .

Had this problem continuously with the dometic ! it is caused by gunk build up inside the sliding rod housing, a spray of silicone helps but it just gets worse again eventually, Have you removed the complete slide and cleaned out to void inside where the rods are ? I used to use a pressure washer to do this and it's amazing the gunk and mess that comes out, it gives a reprieve to the problem but only cure I found was to dump the lot and fit a Thetford ! so much better quality than the Dometic.

I honestly don't know how they can get away with such rubbish, we had many leaks too ! fitted a new slide under warranty and cured for a few months, then it starts again, simply IMO not fit for purpose for full time use.

Another issue we had was the cassette holder under the toilet is very hard to clean after one of the many leaks we had, hence my decision to replace with a different toilet. Not a simple job as I had to replace the outside hatch too as Thetford use a different orientation. But so well worth it now, we have a quality toilet that does not leak and inside the cassette void a flat surface for easy wiping out to clean.

Thank you to one and all for the replies. Funny you should mention the leak, Banjo. We have it as well. it's too close to Christmas nowso will re-assemble the toilet and look at it next year.

I got the new ceramic one, this is it http://caravansplus.com.au/catalog/product_info.php?products_id=9592

Simply chalk and cheese compared to the other removed one, even the seat feels like a proper seat, instead of a piece of flimsy tupperware !

We've had it in now for 6 months and it's just great.
