Draining from kitchen sink on hymer 830 s (1 Viewer)

[MrsBB]

Well we have used all sorts in case pipes blocked. Mr muscle takes 'metal' surface off plug hole so be warned! Traps clear . Used soda , hot water , bleach , you name it we've tried it and still water takes ages to drain away. Beginning to think it may just be how it is on kitchen sink. Bathroom sink empties fine. Anyone any experience of this. Thanks .

Might be a kink in the pipe, you need to try and trace it back as far as possible. And ensure the waste tank isn't full of course!

We had a similar problem(s820), I took it apart and found that the hot water had deformed the trap a new one improved things but it was never that rapid.

Hello, not an 820 but had similar problem on my 584.
The problem turned out to be the German theory that water will run uphill.
I had to reroute the piping under the shower floor.
Now much better but the 25 mm bore of the pipe & the 10 90 degree bends / joints before it outlets to the tank don't help.
Replacement with smooth bore flexible pipe should improve more when I get round to it.

As Barrie said above....convoluted pipe, bends and small bore all slow the flow.
As there is very little head (pressure) to push the water through and the convolutions, along with collecting bits of food/fat waste, make the water flow turbulant which slows it even more.
If at all possible change as much of the pipework as you can to smooth bore pipe with as few 90° bends as is possible will speed up the flow.
not really practical, but avoiding high points and troughs in the pipe run will also help.

Or it may be the water trap under the sink, we took ours out at the flow rate through it was just ridiculus.
