Thetford toilet

Hell yes Greg, definitely number twos. (Aren't they what they are really for?)

As far as solutions go, there are commercial Thetford products available, but the older Green solution is frowned upon because it contains formaldehyde, a quite nasty product both for ourselves and the environment. Thetford also produce a Blue solution which is supposedly more environmentally friendly.

But the cheapest and most effective product plain old Nappisan.
about a lid full in the bottom tank is all that is required. The prime ingredient in this product is Sodium Percarbonate which actively oxygenates the tank contents to quickly break down solids. A product with around 34% SP is best. Home brand Nappisan used to be the recommended one but recent changes to the SP percentage have now superseded this one in favor of others.
I now use Coles Ultra Booster Advanced Oxy.
A drop or two of euclyptus oil can be added to help eliminate any odors if you wish.

Yes you can use it for number2's. We use the green Thetford product as it is supposed to be septic safe. We also usethe pink product in the flush tank. (Ours has a seperate flushing water tank) A lot of people make up there own using things like napisan with sweet smelling aditives like eucalyptis. We use the thetford product as we only do a small number of trips in the van. If you travel a lot then making your ownwould make sense. There are lots of things in forums just search here or google caravan toilet chemicals. I am surprised that the instruction book from thetford didnt explain it all.

We have used Thetford blue but are about to trial the BioMagic granules shortly - the attractive thing about the granules is that the pack is so small (compact for camping)....a little bit is supposed to go a long way. As for the Thetford pink flush addidtive - we had to stop using it because it promoted the growth of black algae in our flush tank.....I now add cheap supermarket disinfectant (generic Dettol types) to the flush water....just a cap full / litre works a treat.

Hi Greg

Please read My Blog on Toilets and consider the environment. If only for #1's, you can empty it every day or two such as in public toilets if no dump point easily available with no use of additives.
