Ikea basin bottle waste (bathrooms) Rattviken, Braviken, Odensvik etc

[MortarThePoint]

Lots of the Ikea bathroom basins seen to come with the same bottle trap with weird telescopic extension. I'm sure there are better replacements available (suggestions welcome), but I'd like to give their setup a chance. That said, the weird telescopic bit feels like it would be likely to clog with shaving residues. Does anyone have good experience with these waste setups?

 

The bottom most part of the parts below is an adaptor that allows the flexible main waste tube to be connected to the house plumbing. I've also copied their diagram of using that to connect to a 40mm pipe. It is a very snug fit inside a 40mm solvent waste pipe, but I expect the material is PP so wouldn't weld. How have others made this connection to 40mm solvent plumbing? I am wondering about Mcalpine's T18-ABS adaptor.

This type of waste is fairly common in France. During my previously mentioned hotel experience when flexible tap connectors were bursting all over the place, there were zero problems with flexible waste pipes blocking or leaking, so I wouldn't be concerned.

Thank you!

These failing is a lot let worrisome than a mains fed flexi failing. I'm trying to limit my use of braided flexi hoses to downstream of taps so between a deck mounted tap and a separate spout. I like the ridgeline alternatives (https://ridgelinetubes.com/flexis/)

We have 2 Ikea basins with these wastes. No issues with them. I probably used a bit of CT1.

I do clean all sink traps once a year to fill some time!

Nestor is right about the yearly clean, that telescopic section is exactly where soap and shaving gunk builds up. I would add that the weak point I see on these setups is the rubber seal where the flex joins the 40mm pipe. It can shift or dry out if the pipe gets knocked during cleaning, and then you get a slow weep that soaks the bottom of the unit before anyone notices. The McAlpine adaptor is a good call for a proper mechanical joint. Whatever you fit, leave it accessible and have a look under there every few months.
