does anyone have the same problem as me with the smaller type waste pipes ie- approx 19mm bore. I find the pipe very difficult to push on the outlet of the caravan, and subsequently have to keep checking if the thing is still in situ.and not allowing waste water to run out onto the pitch. I could do with some sort of soft rubber tube that can be pushed onto the outlet, and then the other end let into the waste tube, either over the od. or into the bore,. has anyone got the same problem, and overcome it, and if so how.I would be a much happier caravanner if someone could help with this annoying problem.
