At the rear of my Cartagena, under the shower, there is a rubber tube coming through the floor with (what looks like) a brass one way valve. The floor around this pipe is very wet and, sometimes, there is water on the floor inside - the carpet is wet as well. There is no sign of water tracking from the shower and the water seems to be coming from under the basin unit - but there is no sign of water leakage from the basin plumbing.
Can anyone tell me what the "valve" is for under the 'van or suggest a source of the leak?
