Vacuflush V Thetford

Greetings Travelling Macs and welcome to all things BOG.

The short answer to you question is YES.
With the newer environmentally friendly tank additives, no problem. Recommend you stay clear of the formaldehyde types as they pose a hazard to septic systems as well. There is a large variety of environmentally friendly additives available.

To bury the tank contents would take the same hole size for the same storage tank volume of either system.

Hope this helps

Cheers

Hi John

If you choose the Thetford, you may be interesting in trying what many other caravaners (including myself) are having success with. The product is sodium percarbonate. The two products most widely available that contain principally sodium percarbonate are Woolworths Homebrand Nappy Treatment Plus and Coles $martbuy Napicare Plus. Most other brands of nappy soaker powders contain other ingredients and less sodium percarbonate so are not suitable. We abandoned using the expensive Bio Magic after trying theses powders as we had less odours when using our Thetford spasmodically with the these powders than with the Bio Magic. It breaks down the solids by oxygenation, and the slurry remaining disappears quickly and harmlessly into the soil. It is also safe to dump in your septic if you have to (or even into long drops) without doing any harm to the natural bacterial processes. We have a large bottle of Thetford formaldehyde stuff which we inherited from the previous owner of our van and i would not use - even disposal of this unused product is a problem. Obviously Thetford leaflet will say to use only their products, just like Toyota tell us to use only genuine Toyota spares - just protecting their interest.

We have never used a Vacu-flush and we have spoken to owners happy with theirs. We have also spoken to a few owners whose toilets have malfunctioned after trips on rough roads. I seems you must have found yours satisfactory even on rough roads in your KK.

Welcome to the BOG.

John,
I think the toilet chemicals are the least of things that you should be thinking about in designing your new caravan.
If you are using it a lot and emptying it almost daily then you can get away with not putting anything in it. We use the green chemical in the bottom tank but only use a fraction of what the recommended dose is, and have no smell or other problems. It can be safely emptied in septic systems and berried if required.

With the chemical system Thetford there is a lot less items to fail compared to a vacuum flush so that is why I would continue with a Chemical type if I was getting another van.
