I am new to the luxuries of having toilet in the van, our new concept van has thetford toilet fitted an i have filled the reservoir as directed but the fluid level is not changing in the level indicator and the pump works but no water is actually being pumped out. This is not the first filling for this unit, it was full when i took delivery. Any suggestions would be appreciated.
Thanks

There is only one way the water will become visible in the tube is if there is water in the tank.

There is always water in the filler tube you need to let the hose run slowly or pour it in slowly to stop a flash overflow and wetting things.

The tank holds ??? 20lts If you pour a 10lt bucket in the filler and the water does not rise in the tube don't pour anymore in till you find out where that bucket full went.

All the best

Sorry and also if the pump runs and no water is pumped and no water is in the clear fill eye tube there is no water in the tank not a good idea to run the pump dry.

Look up Thetford site and look at the cut away plans for an idea how it works.

The toilet roll holder will come out if you wiggle it around and pull hard enough.
The pump is just underneath it.
You will then be able to see both the water level in the tank and the pump tube, which may be kinked or may have fallen off the pump.

Thanks for your responses, i wasn't putting enough water in. I was stopping when the filler arm was full, however if you keep going it will overflow into the storage tank. Learn something new everyday.
Cheers

They are indeed a tricky setup in a number of ways.... while you are there...Thetford recommend the pink flush additive but most usersin mild to warm climates report the development of black algae in that flush tank - had it myself - that too could eventually block the pump - I stopped using it. Some owners stay with plain water in the tank and use the pink flush via a hand held spray bottle
