Waste kit mismatch.

[Buk]

Hi,

I'm replacing my old sink with a new one which has a shallower bowl and the larger 90mm drainer.

As the bowl is shallower, I bought a new P-trap with a longer & adjustable up-stand.

The problem is that neither the original p-trap upstand nor the brand new one will mate with the outlet on the sink kit.

This is sink with the waste kit is situ.

This is the old p-trap:

This is the new p-trap:

This is the nut & washer supplied with the waste kit: top view: bottom view:


And this is a comparison between the supplied nut and the nut on the new p-trap upstand:


My questions arw:
Why are the threads different?

What should go between the p-trap upstand an the botton of the sink outlet?

Cheers, Buk. (Exhibiting signs of mild desperation 🙂

Think you need one of these

McAlpine Kitchen Sink Waste Thread Adaptor Euro to UK T12A-F - 39004016 - Plumbers Mate Ltd

Can't see pics at the mo but sounds like an eu spec waste fitting

Yes. That seems eminently likely. Thank you.

(Another weekend without a working kitchen sink 🙁.

First the sink arrived without the "free" waste kit. 5 days on and they send me a continental fitting!

Grrr!)

Already ordered from Plumber's Mate, but I wasn't going to spend £9 for next day delivery on a £2 item, especially as they don't guarantee it if the order is after 12:00.

For now, I've wrapped 10 layers of ptfe around the continental thread, used the washer that came with the kit and screwed the UK p-trap upstand onto it.

Surprisingly, it seems to be water tight. I've a bucket underneath just in case; but it'll do till the adapter arrives.

(BTW: Who and where are "toolstation"?) Ignore this, I found them.
