Hello all, I have a burstner caravan about 28 years old which I have just got from my brother in law. I would like advice on how the flush system works. I would believe that it is a manual pump system not electric unless I'm wrong. I can open the bowl door but can't get the water to flush through, there is water in the tank, any advice would be greatly appreciated.

Is it the type where you press down the spare toilet roll holder?

If you need help I would try the owners club on http://burstnerclub.co.uk/

Or swallow your pride and just ask the Brother in Law
