3 Technical Questions on the Lip seal for Thetford (23721) C200, C250, C260 and C400 Toilets

Question

I have a 2000 swift caravan with a swivel toilet I need a new top seal is a post 2000 one going to fit
 on 

Answer

Yes it is.

Question

Hi Tom Last year I purchased my Bailey caravan and have a problem with the c200cs cassette toilet. With the cassette blade closed fluid in the bowl leaks slowly into the cassette housing. I changed the lip seal but still have the same problem. The lip seal I purchased was for the pre-2000 model as I thought this would be right, but am now wondering if the previous owner changed the cassette to the later model. Is there a way I can tell the difference between the 2 cassettes. Thanks Bryn
 on 

Answer

The seal that you should have for this toilet is our part 229428 Thetford part 23721, If you have purchased the pre 2000 seal then you have the incorrect seal.

Question

I have a Thetford 200 plunger flush toilet pink solution appears too leak very slightly around the joints of the holding tank
 on 

Answer

If you are referring to the waste holding tank then it is very unlikely that the joints are leaking. It is more likely that the lip seal at the top of the tank is worn which will allow a small amount of pink liquid to run down the outside of the tank and end up at the tank joint area. first thing is to replace the seal, our ref. 129428.

Lip Seal For Thetford C250 Toilet Waste Tank

by moonbeam (29 Sep 2015)
5 star review(5/5)
As usual superb service by leisureshopdirect. The seal arrived within the period one would expect for delivery. Other reviewers of this item did note that the item is easy to fit by following the instructions that come with the seal. The only problem I found with the C250 model, it was very difficult to unscrew the plate by the method described so I eventually had to use a rubber mallet to knock the half entered slide so releasing the screw eventually. Otherwise an easy operation for a competent person. Fitted like a glove and genuine Thetford seal.

Fast delivery. Very easy to fit with the instructions included. Also gives you the chance to give the tank a good clean. Our van is coming up to five years old and I would have changed the seal sooner if I had known how easy it was. Very highly recamended.

C250 Lip Seal Replacement

by Mr Cornforth (18 Aug 2015)
5 star review(5/5)
I used this 23721 cassette lip seal seal successfully for a 6 year old C250 toilet that had started leaking from the bowl to tank joint. The instruction sheet was clear, but since you have to delve into the innards of the tank I suggest you give it a good clean first ! You will also need a spray can of thetford seal lubricant. The removable circular panel on the top of the tank can be pretty tight to turn - a piece of hardwood of the right width gave more leverage than the suggested method of using the plastic closure flap.

Exactly as it said it would do. Easy to fit by following the enclosed instruction sheet, but, as expected, a rather messy job and needed protective gloves due to the cassette tank earlier contents. Used the lubricant seal as recommended when re-assembling and that made the job so much easier
