Non standard waste help

[John D v2.0]

Hi all,

We've bought a Franke RNDH260 sink from screwfix and I'm trying to plumb in the waste. Unfortunately the supplied waste isn't quite big enough (by about a mm) to fit onto a normal kitchen P trap. With a name like franke, I am assuming it's some european metric size.


Should I be chucking the whole waste(+overflow?) out and trying to get a more standard one, if so which one would fit a 46mm drain hole (and 30mm overflow hole)? The plug is rubbish quality so it wouldn't be a great hardship to chuck it.

For background it's just a secondary sink for near the hob so we can drain pans and fill the kettle, but a 40mm trap would be better than 32.

Any advice appreciated!

John ,your not trying to connect a 1 1/2 inch trap are you ? Should be 1 1/4 inch for a basin ?

I am indeed and I hadn't twigged that it might be a basin waste size, I'll grab a smaller waste and have a go tomorrow!

Yep spot on, it came with an overflow and waste in the box. And terribly IKEA standard of instructions.

Your gonna need a few other bits as the trap will accept 1 1/4 pipe and your kitchen waste pipes 1 1/2 ,so a reducer should be on your list

Well it was a good shout but as I suspected it's much closer to the bigger size

With Brexit behind us this kind of issue will soon be a thing of the past!
