Flush tank additives

...didn't know you had a grey waste tank....or are you talking about the cassette?
also, when moving from location to location (I won't say site to site...) I don't drain the hot water as we'd obviously have to refill and reheat...
a waste of water and energy...

It is a cassette, BB. After having trouble with water leaking from a joint from the hot water tank don't want to risk it happening again when on the move, hence the emptying of the tank ( I guess it's only holds about 4 ltr anyway so not a lot to refill and reheat.) I also check for leaks when refilling the unit once on site.......I'm a belt and braces type of guy, as you well have guessed.

We use a few drops of Zoflora in the flush tank. Good pongs and keeps the flush tank clean.

Proterra { and Little Jack }, You have to be careful with standard WD40 'cos it softens many plastics -- they have brought out silicone etc based versions but I've no info on them.
As for the Closing / sealing disc on a cassette I use the Thetford spray designed for that job - I've not checked on it's composition ( it stays in the van) but it is in a spray can which must be good for 5 years use I reckon.

I use Milton in my flush, after being put off using the pink flush stuff because of the black slime that was produced. My thinking was if its OK for babies' bottles etc then it can't do harm to the flushing mechanism and it smells fresh and clean always

I'd be very doubtful about using Milton in the flush tank. Babies' bottles don't have seals and moving parts and the toilet manufacturers often warn against using cleaning materials because of the chemical content.
We don't add anything to the flush water - just like at home.

We have just replaced our seal on the toilet cassette and used olive oil to lubricate it before installing.

Ah - but you could. These things that dangle in the cistern. I wonder if I could lower one into the flush header tank.

We had caravans for well over twenty years. Originally we had a removable Porta Potty toilet, as did many others... The last three caravans had a fitted Thetford toilet, with a separate flush tank to which I always added pink fluid. Rarely did I see black bits in the flush water, but then I have always fully drained the flush tank and indeed all the water systems between trips.
For over three years we have had a motor-home, it too has a fitted Thetford toilet, but it has NO separate flush tank, the toilet flush comes from the underfloor tank just like the taps so adding anything to it is not an option. Even so, I rarely see any black bits in the flush water, and as before I fully drain down everything between trips.
I have a theory therefore, that the presence of black bits or not in flush water, has less to do with what you add to the flush tank, and perhaps more to do whether the water in the flush tank is left in between trips, either fully or partially, and that its actually the damp conditions in the flush system that is causing the black mould which you see, similar to what you see in washing machine detergent drawers, which the OH has also started removing to dry out between washes.

. . . . though what goes into it is the same.

I've mentioned this on a previous thread on this subject but just a word of warning about warranty on the flushing pump which can become clogged if too much softener is used. Probably wiser to use the "pink" stuff if your van is still under guarantee.

I'll never go back to using the pink stuff. My flush tank is now filled with clean water only and I spray the toilet bowl with a fragrant but diluted disinfectant to sanitise the bowl.

We have tried both fabric softener and disinfection in the top tank.
Didn't like the fabric softener as it left white slimy film on the mechanism, the disinfection was ok to start with but then we found when staying put for a few days (MH then) it would settle in the tank and the mix wasn't consistent.
We have now gone back to a 'little' bit of pink in the top tank and a good squirt of disinfection mix every one in a while.

I am with Jill. I stopped using the pink because of black bits. Only used plain water for the last 7 or 8 years .... maybe longer. Don't drain between trips and no black bits.

for what it's worth, a few years ago I mixed the pink in an old 5ltr water bottle to save time when topping up through the holiday. At the end of the week I had a couple of pints left which I decided to keep til next time (call me Scrooge) but when I went back to it about 6 months later the bottle was full of little black bits. It was a clean bottle to begin with and I used fresh clean water, so can only conclude that this has something to do with the breakdown of the pink stuff and nothing to do with seals or pipes in the flushing system

Hope you dont put wet wipes down toilet

Well thanks for all the advise on here - I have been aware of people using Bio Tabs for some time after reading other forums so after reading through the thread I bought some tabs from Lidl and put one in the toilet and some Zoflora for the header tank, drained what pink was left and put in a capful
lets see how it goes and I will give an update shortly (we are away at the moment so ideal to try it now)
