    Our MH is fitted with corrugated waste pipes on sink / shower / washbasin, and for the life of me I cannot see why any manufacturer would do this. It is obvious that gunk will settle in the corrugations and possibly give problems with nasty niffs. Has anyone replaced these pipes with a smooth walled alternative and if so where did you buy it?

    I can only imagine that it's because it's very flexible and cheap.

    I can't imagine it's too difficult to change once you get the rigt size.

    Our is in rigid pipe and corner elbows.

    I'm sure Martin is right.

    If I remember correctly the corrugated pipe on our Autoquest was 28mm so I Googled 28mm plastic pipe and came up with several results, including some stocked by Wickes.

    The corrugated stuff goes around corners easily, just be careful with plain walled that nothing is too tight and kinks it.

    Is the inside of the pipe actually corrugated? We bought a short length of corrugated pipe from a caravan spares shop for a repair and the inside surface was smooth.

    "Corrugated pipe" is actually reinforced walled pipe which doesn't kink when bent. It is smooth on the inside. You could replace it with a better quality or even non-porous pipe which would eliminate the possibility of waste pipe aroma's. Lee Sanitation would probably supply what you require.

    I changed the sink corrugated waste pipe to a car radiator hose pipe...just go to a car/van parts supplier and match up the as near as shape to your needs as possible ...you'll never need to change this pipe again!

    Many thanks for all your inputs, we will check to see if the inside of the pipes are indeed corrugated and if so we will change them,

    Something else to consider..
    We started suffering from the dread pong up from the waste pipes after several weeks of being in one place.. A good temporary fix was simply pop the plug in the sink.. however, far from a long term solution..
    Any ways... I thought I would take a quick nose ( pun intended LOL ! ) under the sink to check out the trap in case it was blocked up a bit..
    To call what I was looking at a trap is like calling a row boat the Queen Mary !

    Once I have got the gearbox sorted out the first job I will be doing is removing the thing and fitting a decent bottle trap under there !

    Oh, a tip passed on to me by Richard ( Scotties ) was to tip some pure fresh orang juice into the tank ( via the sink ) and let that slosh around for a while.
    We put four litres of Morrisons finest ( 74p a litre ) in before we left Zahora.. I drained the grey tank at an aires near to where the trailer wheel came adrift ( just north of Rouen ) and there was absolutely NO smell left at all ..

    Is that any different from This? I bought a 5m length to make it easy to empty the grey tank at home when returning from a trip.

    It looks the same type of thing. He got one for the fresh too, but that's blue. He says It's good quality stuff. He got all his windows from cak , and lots of other bits n bobs.
