My van is fitted with a Thetford C200 the electric version The problem I had been having is with the electric switch despite sealing the best I could, they just rust out, even with the tank empty it seems you only need a dribble of water in the fresh water tank, and the condensation will rust the switch.

 

Well after 3 replacement switches at £25 a time, I decided to convert the toilet to a manual pump the whole thing was £25 same price as the switch. All went well until I had the dreaded pink flush fluid growing black algae, blocking the flush and putting pressure on the pump, breaking it.

 

So I'm back to square one. I decided to reinstate the electric pump while away in the van by first unblocking the flush blockage with diluted bleach and some wire. I had an old 12v switch that was used on a car and that got us by for the holiday.

 

On my return home I set about finding a switch on ebay, the horn push type, and low and behold I found the very thing for just £2.89 inc P&P. All I needed to do was drill out the place where the Thetford switch was to 26mm, and drop the new switch in, and it work a treat!  I have ordered up a spare in case it rusts away but to be honest it's much better quality than the genuine Thetford replacement.

 

So before you order a £25 original check this option out.

The black stuff coming out of your wc is algea caused by flush being left in the rinse tank easiest way to clear this is by draining the flush tank and refilling with a drop of MiITON and water to the top flush the toilet 2/3 times so as to clean the pump as well leave for approx. 1hour and then flush the substance through the system you might have to repeat this again if this does not clear it all

regards Martin 

 

ps it worked for us and we had quite a lot of algea

To be honest, we have never had a problem with algae since we stopped using the pink fluid.
You don't do it in your home toilet so why bother in the van which is left alone for days at a time without use?
I know that the makers have claimed that it isn't their stuff to blame but it's funny that when you don't use it, everything is fine.. ...Peter

I stopped using the pink flush fluid due to the algae, switched to Fenwicks top and tail years ago and no problems since.

Thetford's Pink seems to generate mould.

 

I just use water these days.

I gave up Thetfords pink stuff and started using Blue Diamond's pink stuff instead - no more black bits.  I always empty the flushing tank after every trip too and I think that this helps in avoiding problems.

I don't understand it. So many have a problem with Thetford pink and I don't for a second disbelieve. However, I use it all the time without a problem. I even leave some in the tank in storage except for the winter.

What am I doing wrong (or right).

They've changed the formula since, but mud sticks. 

 

I had hell of a job getting rid of the gunge so I'm another that wont use it again.

As discussed on here a few weeks ago,I didn't think I had a problem until I filled the flush tank with the garden hose instead of the watering can,when it was full the grunge just poured out of the filler hole,this carried on for ten minutes,it was running across our driveway .
I stopped using it,and now the flush works much,much better .Dave.

I bought 25 lt of a pink fluid off eBay and never had a problem since . Not sure of the make but it was cheap and does the job without black bits now .
