    How doo,

    How fast do your sinks drain?

    Mine seems to drain slowly and have some kind of 'air lock' stopping it draining at reasoanble speed. If i waggle my finger around the plug hole i get a load of gurgling and bubbles and it the drains quickly. It seems to me there should be some kind of vent to sort the pressure differance out.

    Its also does it with my drain down tap. Today we packed up and as I went to put the grey hose away it started flooding out. Took about ten mins to drain after i thought it had been draining for the three days we had been hooked up !! It felt like id dislodged the air bubble stopping it flow freely. There certainly isnt any hard food like stuff stopping it as im very carefull what goes dow the plug hole.

    Anyone ??

    :)

    Have you taken of the trap under the sink? The drain pipes are only about 3/4 inch and are easily blocked.
    Remove the trap and waste pipe from it, you should see the blockage or push a piece of stiffish wire down the flexible drain as far as you can. Or maybe blow down it.

    Folks, im certain its nothing solid blocking it as ive been ultra carefull. No plate rinsing, just coffee and tea dregs mainly. Any washing up has been done using camp facilities.

    I wonder if the pipe has a sharp bend or kink in it ..

    maybe do to with the gravitation pull of the earth atm , as i "think" my sink in my home is emptying slower than it usually does, until i swirl my fingers in the water until it empties in a anti clock ways direction , ofc that is all assuming you believe in such nonsense :D

    The kitchen sink on our Autosleeper drained slowly if we were up a bit at the back. I checked the sink trap and it was clear, I just think the manufacturers don't put enough angle in the pipe work to enable it to drain freely
    And I wouldn't poke any wire down the sink, many of the waste pipes are just a push fit and you could easily dislodge them

    The trap is still worth a look, it's an easy check. Have you had the van from new?

    many converters dont fit a vent on the waste tank. even though you can see it has a drop, in the pipe, the back presure from the tank slows down the water flow. wiggling your finger round the plughole introduces air so speeds up draining

    We had our van new this summer. I noticed straight away that the kitchen sink was slow to drain (the bathroom was fine). Close inspection underneath the kitchen sink showed the waste pipe taking the water away - after the trap - went slightly uphill, instead of down!!

    I wondered if I could carefully move the pipe slightly so it had a downwards slope, but in the event was unable to. I let the dealer sort it out - they removed an inch-and-half from a vertical downpipe, so the near horizontal pipe changed from 'uphill' to 'downhill'. And it drained perfectly from then on.

    If you look at motorhome ( and indeed caravan ) waste traps they are pretty crap.. The design is far from conducive to a free flowing disposal system !

    I replaced ours with small domestic units.. had to make up adapters to fit the pipe work but other than that a 10 minute job
    We still all sorts down the sink ! Treat is the same was we do the ones indoors in fact

    Why not.. stops em worrying about a slow draining sink..
    But rather than coke I would try LSD
    Not only does it stop you worrying but it is AMAZING the pictures you can see in the water.. of course there is the small issue of the drain pipe sometimes turning purple and green, escaping from under the cupboard and dancing on the worktop ..

    Cheers folks.

    Yep, only 1k on the clock. I suspect that the hose may have a kink. The fridge slides directly under the sink so maybe as it was fitted a hose got a bit squished !

    Our autosleeper has a length of horizontal pipe run from the sink. Any hint of a slope and the sink drains slowly. Don't ever be tempted to use one of those rubber sucker sink plungers to force the waste water down as the pipework is often simply push fit without adhesive and will spring a leak easily.

    Seems like the older vans might have had it right.
    Our latest van, at 19 years old, has drainage so violent you wouldn't want to put your hand in the sink when the plug comes out!
    And on board water tanks too, and its British built.....
