New sink doesn't fit trap?!

[Giblets46]

hi All,
We have a new sink and trying to connect the drain to the bottle trap, however the pipes will only seem to butt up?!
Not sure what the solution is to this one? Is there a seal for this? Should be 40mm

Is it an Ikea one? They're usually a non standard size so you have to use their waste kit

Many thanks for the reply, it's a Valle Albany sink with their waste fittings

does the white nut not (with some force)push up ?

Did they supply a trap kit ?

Hi, tried pushing the trap up, the bottle trap just won't fit inside the sink outlet. The inside diameter of the sink outlet is petty much spot on 40mm.

if a fitting kit was supplied it should be used .

This euro-uk transition fitting could work https://mcalpineplumbing.com/plasti...ings/s12a-fc-european-uk-waste-outlet-adaptor

or the basket waste fitting could be exchanged to one that fits your trap.

If the nut will tighten onto the thread then just file/sand out the inside of the waste until the lip of the trap fits in and the seal is tight to the leading edge. Might need a bit of a good push. Had to do that on many of these cheaper sinks/wastes to make a standard trap fit in properly.

We had similar with a franke round sink from screw fix, i needed an adaptor to sort it which Screwfix have in stock too.
Our problem was then the height gain.

The sooner we're out of The EU, the better!

Thanks for the replies, having taken the parts out, had a much better look I independently came to a similar solution to Madrab, I chamfered the inside of the waste so that when I tightened the joint the bottle trap got pushed into position and seal made!

Rules for Ikea items:
1. Don't buy in the first place
2. If someone has foolishly ignored 1 then throw away all supplied waste fittings and replace with proper ones.

3. Slap on a load of silicone and scarper before it leaks

Recently had a similar situation with a basin trap from Bathstore... Backnut on the trap wouldn’t slip over my 32mm waste that I’d 1st fixed, so I went out and bought a McAlpine one... later on, as I was tidying up, I found a stray backnut in the box of stuff I’d used to store everything in... it was meant to replace the one in the trap and would also go over the 32mm! Didn’t spot that when I was opening all the packaging and cracking on. Will remember for next time
