I have never heard of one!  When you drain down for winter, make sure that you pump out all the water you can(depends on the model and what type of pump you have) from the flush tank. Don't rely on the drain tube alone, as this will often leave some water remaining in the tank!

i have asked thetford about making an anifreeze in 2008 for the header tank and got a reply,whether you want to use it is up to yourself.they did not say no or yes.

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,
