    Hi There. This is my second van conversion and I have bought a Thetford C200 CS toilet that has electric flush and an inbuilt water tank. Because of the design of my van there is nowhere for me to install the tank so I need to convert it so that it flushes from the van’s water tank. I thought I had it sussed but I don’t think the pump that comes with the toilet is strong enough to pull any length of water or if I put it directly on my Sureflo pump it just pumps continuously. does anyone have any ideas???

    You should be able to replace the pump with a different model.
    Have you tried using the built-in pump to draw from the thank?
    I normally only flush for a second anyway (to save water filling the tank).

    Hi Darren. Thanks for the
    Hi Darren. Thanks for the reply. I’ve tried running a feed from the tank to the pump that came with the toilet and it wont draw the water. I’m wondering if it’s not powerful enough to draw it. If i put a small draw length on the pump and drop it in a bucket of water then it works fine. Do you think it would work if i move the pump closer to the tank and then it will have to push the water instead of pull it??

    Any 12v pump with the correct connectors will do. I bet you could find a good one on eBay.

    Or use 2 pumps. Add one further down the pipe, keeping the current one in place.
