Sink waste broken

[seanandjules]

So our sink waste broke spilling dirty water onto the cutlery below, lovely.

Took the sink off and it's apparent why - the pipe going to the waste is rigid with no wiggle room and the fixing for the sink plug thing is plastic, so all the vibration from the van has stressed and broken the plastic fitting.

A couple of question:

1. Can I replace that horizontal waste pipe in the first pic with a flexible one? I assume not, as why anybody would something so rigid into a plastic waste trap in a van that moves is beyond me.
2. I got the wrong sink trap (white one in the second pic) - it's 20mm rather than 25mm. Any issues with simply putting a reducer on there? Is 20mm too small?
3. How Pilote / whoever thought that a plastic fitting under stress was a good idea is beyond me. Anybody know what drugs they're on, as I would love some.

Thanks all

Ones that make them have reocuring customers

You can replace with flexible but you would ideally not want any ridges or anything to reduce flow, or catch debris. In reality the pipe should be fine, being rigid as the two items shouldn’t be moving separately. I also would fit a waste with the largest outlet possible.

Ours broke after a few years and that was on a flexible waste. I think I'd just replace it with a new one and if it goes again think of other options. We were in France at the time and the replacement one was a hymer one probably the poshest bit of our van!

Id replace like fir like.
Has anything junped up from the drawer and damaged the fitting as they are usually very good and dont tend to move much.
Is that rigid pipe free to move?

How about a short length of hose between the existing fittings with jubilee clips? Give that little bit of flexibility to cope with any vibration.

Had similar with a flexible pipe although mine just pulled off rather than broke. Eased the tension by slightly rotating the bowl and refixing in the new position.

Where is it actually leaking from? I recently had exactly the same problem with exactly the same waste. This waste has a trap and is designed so the bottom section is removable to clean the trap, mine started to leak from the seal in the bottom, nothing to do with the outlet pipe (although mine is flexible). It may be frost damage as there is water in the trap that never drains away.
New ones are available at around £30. But I've just glued the bottom on and siliconed as an extra measure and it no longer leaks.
Going forward I will treat it bicarbonate every now and then to keep the trap clean.
