On our last outing a few months ago (And the first one too, might i add)
I noticed when taking the toilet casssete to the waste point, it was leaking.... Looked as though it was coming from the Seal area where the port opens and closes...
I am not sure of the model, as i'm not up on Caravanning yet, but wondered if parts were readily available?
It must be easy if I can do it, and it really was very simple, as Micheal said in his post you just remove the screws, replace the seal and screw back together (the seal had fitting instructions with it). Ta da! Our van was a 1993 model and the seal came within a few days of my order as well.
Thanks for the advice, went off to Local Caravan Shop today, and they had lots of spares! Cost me £9 for the seal, and 5 minutes of my time!
Leak has gone, but there still seems as though there's a smaller leak which is from a hole, which looks like it has a clear / white seal inside it (About the size of a 1p coin)
