This is a known problem and my dealer replaced it under warranty.

There may well be more than a modicum of truth there snags, however its never good for a manufacturer to get a reputation for unreliability and I believe they have admitted that by giving out free upgraded replacements. My feeling is that new designs aren't thought through enough before being released on to the market and that we tend to do in-the-field testing for them.

Mine did the same

 I got the full, watering can two shots of pink stuff filled it only to watch it drain on my feet

I complained/moaned about it on swiftalk and i got a reply from thetford saying if i rang their customer services with model number/,s/n and code number (they are under cassette at the front) they would replace with their new modified pump f.o.c their phone number is customer sevice 0114 273 8157

My pump also suffered in the big freeze, even though properly drained. But I only found out early this week on our first time out this year. Luckily, if you can call it luck, it dripped rather than poured out, and I managed to empty the tank.I took the toilet out and found the problem straight away.

when at home today I searched the Thetford site for the product but could not find it. Instead googled C 250 CWE and it brought up this forum. phoned the number given by geoff+emmy and Thetford are sending me a pump, no charge, great service..They did ask for my caravan vin code, so have that handy if your phoning. The caravan is about a year and a half old. Thetford told me their products are guaranteed 3 years. Thanks for the number, thought it was going to cost me a packet.

is it this one/click on

Submersible Pump for all Thetford 12V Toilets

I thought that I had been lucky enough to avoid any frost damage last winter but it must have weakened it sufficiently to fail last week whilst on holiday in France.  I managed to bodge it with silicone sealant to get bye till we got home. I phoned Thetford in Sheffield after we got back, they were very helpful and said I was due a free replacement. As the van was going into dealer to have a replacement centre window yesterday, they fitted it at the same time and all is well again.

Strange that frost damage reared its ugly head so long after the event, so keep an eye out for pink stuff leaking when you go to empty your thunderbox!

I use my van all year round but when it is not being used in winter I put car radiator anti- freeze in the toilet flush tank.  It doesn't need any in the system when the van is in use as the heat in the van stops the tank getting too cold.

It doesn't cost much as it's only used when the van isn't being used and it isn't necessary to use a high concentration to protect the system.

Mind,the flushing water is a funny colour!

i asked in 2008 and this was there reply.

Thank you for your e-mail.

Any antifreeze used should be non acidic and non corrosive. Generally any non toxic anti freeze that is mono propylene glycol based should be ok. If using anti freeze please adhere to the manufacturers instructions at all times.

Please refer to your Thetford Users Manual with regards to using the toilet in the winter. Please be aware that Thetford accept no responsibility for damage caused by any anti freeze products.

Kind regards,

Thetford Customer Care.

... But I don't know how to get to the switch to replace it. The button is blue on a silver background pad if that helps...
