Hi folks, I have a problem with the washbasin leaking out onto the caravan floor. How do I get access to the waste pipe I think there is a split in the pipe..
Caravan was made in 2008.

Welcome to UKCS.
Google your question: AI will give you a number of solutions. On the same page online, I see there is an Eldiss owners club - your problem will probably have happened before. And there are YouTube videos of taking things apart.

Thanks for the info.
I have had a look underneath the caravan and someone has connected the waste pipe from the bathroom washbasin against the direction of flow and connected it to the waste pipe from the kitchen sink.. this may be causing the problem. I intend to reconnect the pipe into the waste from the shower then ii will drain away a lot easier.

Hi, dont connect it to shower waste pipe or it could drain into shower tray. If its like ours the wash basin lifts out after removing the plasic clips from around top outer edge of wash basin.

Yes my washbasin folds away, how can you get access to the waste pipes from inside the caravan?
I did think about removing the outer case of the cassette from outside. I think that either the small waste pipe below the washbasin may have a leak or the basin waste pipe is leaking.there does not seem to be a way of inspecting the waste pipes without dismantle the plastic coevering from inside. Any ideas?

Would seem like you may need to remove whole unit off wall.

Yes that may have to be removed. If I get a small inspection camera down the side of the waste pipe I may be able to see the problem. Thanks anyway.
