Auto sleeper say the waste pipework on my van ( and other new models) is ( and I quote from their literature) "Large bore Waste Pipework for efficient drainage", but it quite obviously isn't. Mine is about 3cm, just over an inch, and takes 10-15 minutes to drain. Compare that to a lot of European vans that seem to have 3 or 4 inch pipes and can empty out in a couple of minutes, muggins here feels stupid when theres a queue at the drain point, my van looks like it has prostate trouble! :Blush:

Is this size pipework common for UK built vans? I might have a go at increasing the bore size.

The waste pipe on my French-built Rapido is 30mm, same as yours.
Mine drains quite quickly to start with as it has the pressure of all the water in the tank behind it. As the tank gets almost empty though it slows to a trickle.
If there is a queue behind me I don't bother waiting for the last dribbles.

enlarging the pipework wont help....the hole in the tank is still 30mm.

i have never seen a motorhome with a 3" or 4" bore grey waste outlet.....even Americans are only 1-3/4" grey and 3" black.

the problem could be a build up of fat (cooking and soap) and minute food deposits around the tank outlet and in the dump pipe.

It has done this from new, and its only 3 months old. Obviously, if I increased the bore of the pipe, I would put a larger bore connector in the tank.
Nice to know that your Rapido has the same size pipe, mine empties like yours, fast at first then lots of dribbling.
I guess I just need to take more time emptying the cassette and filling the freshwater tank.

Our pipe is the same as everyone's here and our experience is the same too; fast at first then trickle as it gets near empty. Obviously worse if the van is on a slope. But we tend to use a waste hog and just empty that every day, then when we come to decamp, the job is already done. They take up a lot of space but we have found that it fits perfectly, thin end first, in the drivers side, middle storage space between the floors.

Hi on our auto sleeper rienza it takes ages to empty the waste. The pipe looks like 3/4" over flow pipe that it comes from. We use the waste tank cleaner on a regular basis recommended by dave newel but its still slow. Just got used to it now. Ivory55

ours is 40mm and that is fine....but I have reduced the outlet to 25mm wth a tap to make it easyer for me... and that goooooooooshes out fast ::bigsmile: so you may have a little blockage say some grease or food...or is yours a flexy pipe and is it sagging in the middle???mine is rigid house hold 40mm fitted pipe by rapido..check your route the pipe takes from the grey tank to exit hole and look for places that could be a problem

Just set your grey running while you do the toilette and fresh water ....:Doh:job done.....OR GET A LONG VACUUM TYPE PIPE ABOUT 4 TO 6 MTR LONG AND STAND AWAY FROM GREY WASTE POINT SO OTHERS CAN EMPTY..... RUN YOUR LENGTH OF FLEXY HOSE OUT THEN YOU HAVE ALL TIME IN THE WORLDTO EMPTY AT YOUR LEISURE...simples

Mostly, if we're touring, I empty the tanks daily. I use a collapsible bucket that easily fits under the grey water outlet. I've also seen people use a plasterer's bucket, presumably because they are very flexible and will squeeze under the outlet.

Its a rigid pipe that comes straight from the base of the tank to the side of the van. Maybe I should let the tank fill more, but the sensor has been faulty so I have been emptying every day. Still takes forever till its all gone.
I might try some water softener too, when I took the van back to the dealer to fix the sensors, they dropped the waste tank and cleaned it out. It didnt look ( or smell) too pretty in there, and that was when it was only just over 2 months old!

I've seen plenty of other vans in France that just open the valve and there is a deluge of grey water that lasts perhaps a minute or more, while mine just dribbles out. :Blush:

Had the same problem with our grey waste draining . Same as yours the tank took about 10 mins to empty . I knew there would be no build up of food waste or grease causing this.Done the deed one day while the tank was draining >> Crawled underneath , fingers in to the drain hole , lo and behold felt a bit of plastic moving about . Managed to remove it . What was it ? >>> the piece of material left from when the tank was built/ fitted and the drain hole bored out. From using a saw cutter bit , the entire diameter piece had been left in the tank . Therefore pressure pulled it down to the drain hole , partially blocking it when the tank was being emptied .>>> After removal of that , tank empties in a minute or two.:Smile:

:Eeek: because we keep the plugs in to stop any smells they must be removed when emptying tanks as it can cause a vacuum and slow the flow /well some would not know this :ROFLMAO::ROFLMAO::ROFLMAO::thumb:

It's got to be down to how much you put in, A small amount will take longer to drain, also watch out for stupid drain points that have the wrong camber so that your front end is lower than the back and you cannot get in the other way round. :Sad:

Seen a few of those all over Europe.

I have the same problem with my Sigma, Allan. I use a Fiamma Roll-Tank underneath the M/H and rarely have to store grey water on board even on an Aire.

We rarely use the plugs, but all the drains have traps on them, not sure about the shower, but we never get any smell in there
