Like a lot of us I use Thetford Aqua Kem Blue & Toilet Fluid in our motorhome toilet cassette. When I leave the motorhome for 2-3 weeks the toilet cassette will have the chemical mixed with a half inch of water left en situ.
The question is will it freeze? Should I do anything else regarding the toilet cassette? The rest of the wintering I am now au fait with.
Thanks in advance for your guidance.

Although we do tend to use the MH at least once a month.
Never had a problem

Dorset Driver. We had many a cold night in wiltshire last winter where tempetatures reached -°C. Was it a problem? No.
Will it be a problem for my motorhome. No, as long as I am prearmed with the knowledge regarding the toilet cassette from fellow experienced motorhomers.

I drain the cassette. It's a habit of mine. We have some unpredictable cold nights down to -14C every few years or so. I doubt whether any damage will be done if you left a bit of water and chemical in the cassette. You can buy anti-freeze that is suitable for motorhome water tanks/toilets - don't use van anti-freeze.
Posted on 10/09/2017 15:32 by KeithandMargaretWhy not just take the cassette out and put it somewhere you know that won't freeze - like in the garage or shed or under your bed?

KeithandMargaret. What a brilliant idea I thought until the day wiffey uses the toilet without returning the cassette....ooh the mess.
My gut reaction is with just a half inch of water and thetford toilet chem we'll be fine. If I'm at all concerned then I'll add a dash of toilet antifreeze chemical which is available.
