A Good Freshen Up Was Needed!!

These are really simple to swap over!! A good refresh means no smells come up and it now doesn’t leak when you carry it!! Leisure shop direct offered a good efficient service and I would have no hesitation recommending them!

Works well.

Also Fits C500 Series


5 star review(5/5)
As other reviewers have said, the seal seems to be pricey for what it is. Not the most pleasant job as the valve mechanism needs to be dismantled on the Thetford C500 series of toilets after first removing the complete valve unit from the holding tank. I put a smear of Vaseline on the new seal. which has completely cured the effluent leak.

LIP SEAL FOR THETFORD (23721) C200, C250, C260 AND C400 TOILETS


5 star review(5/5)
Easy to fit though photographs in explicit instructions could be more helpful - when everything is black, it is difficult to distinguish between parts. Also, it was very difficult to swivel the assembly to remove - you need more leverage than the lid provides, a piece of wood worked perfectly. Delivery was very quick.

Exactly As Advertised

Lip Seal For Thetford C250 Toilet Waste Tank


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.

Lip Seal Thetford C250 Tank


5 star review(5/5)
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


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.

3 FAQs on the Lip seal for Thetford (23721) 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
by Johnnie Walker
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
by Bryn Lewis
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
by Syd Beaumont
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.
