Plumberzone - waste pipe standards?

[Last Triumph]

Just installed a kitchen sink purchased from Taps UK and have come to hook up the waste plumbing to find none of the supplied fittings work with the existing pipe work.

On further inspection the sink is German (Schock) and I'm wondering if they use a different standard pipe size to UK?

It's all compression fittings that came with it and the male ends measure exactly 40mm O/D, whereas 40mm UK pipe is actually a nominal size with a larger than 40mm O/D and smaller than 40mm I/D.

The sinks come with a bespoke strainer/drain piece that cannot be swapped for anything else as they fit the base of the sink in a certain way, so I have to find a way of converting from this weird size that nothing in the plumbing aisle at B&Q whether solvent weld, push fit or compression went near.

So.... do Germany use a different standard, and if so, and assuming I'm not the first person in the UK to ever come up against this issue, can you get adapters to suit and if so, where is best?

Screwfix do an EU-UK adaptor. Give me a minute.

Pics of what you have under there and where you need to connect and I'll see if I can help

Adfter some reading up, it would appear that Europe use 1.5" or 38mm (nominal) where we are at 40mm nominal, therefore to join the two systems, I think I need two of these...

That looks like it should do the trick, a lot of these generic waste kits that come with these sinks are a bit pants in general, its sometimes worth buying a McAlpine tyoe equivalent and swapping the full thing out.

A couple of mm, surely a man of your abilities could wind enough PTFE around it to fill the gap.

A fixture, lathe and some imagineering has seen a solution Mr Whitworth would be proud of.
