Grey Water Pipes
Hi,
I will be grateful for advice on piping away the grey water to a drain on a super pitch. I have tried flexible hose but the dips create pressure and slow the flow, what have you found to be the best combination of rigid pipes and corner pieces, dia. and lengths for touring on a variety of pitches. Many thanks for your help.

Hi
rigid pipes are better but think about storage when travelling? Saying that you could always have rigid pipe in 1 meter lengths with joiners and enough corners to work on any pitch. Then store in a bag in the locker. As long as you have a fall from the van to the drain, could use wooden blocks to prop the pipe?
Cheers

Foa a long time I just used the front end of an old vacuum cleaner hose which used to breakdown into three sections. I later added a a piece of flexible sink drain hose bought at the local plumbers which allowed some flexiblity to go round corners. Worked a treat most of the time. there are lots of ways you can do it, I have even seen smaller sized house guttering used. I agree rigid pipes are better.

I've been using this for over a year now and find it both effective and convenient to store - unlike the coiled hose or rigid waste pipe. I bought two packs (8m) which covers every eventuality and using the special support pegs means that you can lay it out with a gradual fall on the piping, to aid drainage.
I agree, it is expensive, but on the other hand takes up so little room in the storage bag that it now lives, permanently, in a locker in the van.

Also very good for lengthening the bit that came with our MH to deal with some of the ridiculously positioned CAMC Motorhome waste points.

We use a 3mt length of 32mm rigid pipe that attaches to the outlets and then this slides inside a same length of 42mm pipe with an elbow and if needed a short length of same size.
We have used this on service pitches for a few years after seeing it displayed on another caravan page.
To support the pipe we have a few rock pegs of various lengths with pipe clips bought at Wickes and drilled out to slide onto the rock pegs.
The 2 lengths of pipe obviously slide one into the other and travel upright in the shower with a stop end fitted. We wash the pipe thro before travelling with a good amount of clean water.

If you zoom in on the photo of the pipe trailing from our MH you will see an adaptor between the large diameter length supplied by Hymer and the two sections of Colapz pipe. This is a universal fitting suitable for all normal diameters. It can also be pushed directly onto the outlet on the van. I bought it from Colapz when I purchase the pipe kit, I think it was £6 or £7.
It will of course depend on the diameter of the waste pipe on your MH if you need an adaptor. Ours is a fair bit larger than the collapse pipe, which I think is designed to fit on a 29.5 MM outlet.

Thanks SteveL the Carado is from the Hymer family so probably the same size as your outlet, think its 40mm. We didn't get an extension pipe with our van so would be attaching it direct to van outlet. Did you cut adaptor down or did it fit your van without?

It goes up to about 55 MM and there were instructions about cutting down. However, with the design of our discharge pipe I couldn't see any point. I just push it over until it gets to the correct diameter (as you say about 40mm) and it seals just fine.
