Yes
Its probably a long shot I know, but has anyone plumbed one of these in? The outlet connector appears to be a US size and I'm having problems connecting it to UK 40mm push fit waste pipe. I can't seem to get a sensible answer from where I bought it.

The trouble there is: 40mm push fit is a different size to 40mm solvent or compression.
Unless you are familiar with solvent fittings, stick (sic!) to compression fittings. They'll account for any slight differences in size.

Push fit is a waste of time. :)

I've fitted a few and repaired and replaced a few more.
 
No problems here.

Thanks. Would you say 40mm compression is smaller or larger than push fit? If smaller then that's my problem sorted.

Push fit is smaller than compression.

Dejongi has used compression fittings.

Damn it, if my push fit won't go in (and it's the smaller of the two) then compression definitely won't fit.

Next size down is 32mm compression/solvent.

Otherwise it is an adapter of some sort. You can get adapters for shower wastes (traps) that cover multiple sizes to 40mm compression.

The other thing to consider is outer diameter of 32 and 40 mm solvent fittings are different (obviously) from the pipe diameter.
 
As above, once the ICE motor starts running, the vibration transmitted through a metal sink is more 'amplified' than a ceramic one. Thus that vibration transmits into the 'push-fit connectors. Also, if fitting the ICE onto a mrtal sink, the tightness and stability of the motot unit connection must be absolutely square or the whole unit will oscilate (even the low power ones) and the outlet pipes will vibrate to the point that even the seals on the compression 'nuts' could loosen. Sadly, I speak from recent experience of a poorly mounted ICE in a Stainless Steel single round sink in a food prep are of my kitchen. Professional tradesman my ^rse. Sorted by a guy who has fitted them for 25 years.
 
Sorted! I finished up taking my micrometer around a couple of merchants and found a manufacturers pipe that was .9mm smaller than the one I was trying to use. Why they all call it 40mm I'll never know.:rolleyes:

Most plumbers merchants call it 'inch and a half'. All the trades are stuck in the past with 2 by 4's for wood, 8 by 4 sheets, inch and a quarter/ inch and a half/ 2 inch for waste pipes etc.

Sorted?

You need a few towels placed under/around before using it, it'll make a right mess of your carpet! :D

`Sheets` eg plasterboards have been metric one way & imperial t'other for many many years, governed by 18" centres for replacing on studding/joists. .
