1 FAQ on the Thetford C250 C260 Complete Holding Tank Mechanism

We have a problem with our cassette toilet. The blade is very stiff to open and close and also the holding unit is leaking into the cavity (as if the seal is not correct?). The model on the toilet itself is C250CWE but the number on the holding tank is C250N11 X066C01. Do we have the correct tank for the toilet? have been browsing on internet and noticed a lot of problems with C250s....can you advise please? thank you
With the problems that you have it is probably best to replace the whole mechanism on the toilet. This is our ref. 237827.

Easy Solution To Repair

by Graham Archer (26 May 2025)
4 star review(4/5)
Damaged the flanges when trying to remove the original unit, as seal needed replacing. More expensive than just renewing the seal, but very simple job. Would do this again rather than dismantle dirty unit to renew just the seal. Only complication being the inclusion of a white bracket,which in most cases is not needed, which is located on the top of the tank cupboard. No instructions with this caused confusion.

Economical Solution For A Non-functioning Holding Tank

5 star review(5/5)
This product is very easy to fit - once you have worked out how to remove the old mechanism - and is better than half the price of a new holding tank .

Tank Mechanism

by Camper man! (21 Sep 2018)
3 star review(3/5)
Thetford 250/360 holding tank mechanism complete. Biggest problem in replacing this is the removal of the old one the reverse position of the blade does not give enough leverage to break the seal vacuum. I had to use several doses of WD 40 before it would move. Some form of paddle lever with a handle would come in handy! Once off the new one was easy to fit but use some silicone grease on the seal first!

Thetford-c-250-c260-complete-holding-tank-mechanism, this recent purchase was an easy swap for the my damaged original. The enclosed pictogram style instructions were useful.

One word PERFECT.

Excellent Service

by Motor Homer (08 Jul 2015)
5 star review(5/5)
I was having a few problems with my motorhome toilet cassette tank so contacted Leisureshop via email. I explained the symptoms and received a prompt reply suggesting what the problem was and even the part number I needed for a replacement. The part arrived earlier than expected and it was easy to fit. It also solved all my problems. Overall, this was an excellent service and I will definitely buy from this company again.
