So, where the pipe enters the unit you have your T, and then carry on up to the sink bottle trap.

 

You use the other branch of the T to connect a WM upstand to, ensuring it is to the side of the bowl of the sink and ends as high up as is possible.

 

I'm with you. Hard to visualise while enjoying the tones of Faithless at isle of white. 

 

Waste comes in, immediately a tee, one goes to a standpipe and the other to the bottle trap. 

 

Done plenty of pipework in my time but always used a combination trap. But now I'm open open living, this is what I need to be doing. Cheers Nick, as helpful as ever beyond the call of duty.

I've been playing with my pipe this afternoon, and after that I thought I'd look at the plumbing under the sink. I've mocked this up with any old crap I could find in my plumbing box, so imagination is required. 

 

Then just a bottle trap at the end of this and Robert is my father's brother? @Nickfromwales

While you're here Nick, any recommendations on a bottle trap that isn't sh1t3?

McAlpine is industry standard stuff. Floplast also good. 

 

Some are telescopic to make life easier.

For this instance the water dropping 600-700mm max from the upstand will never attract a vacuum so will never need any air admittance

Thanks for clarifying, I had in my head that locked air could be an issue with the high pressure outlet, not sure why.

Pretty straightforward, just need to cut the standpipe to size. I ordered the "upgrade" you mentioned in a previous discussion which is compression elbow and a spigot for the top of the standpipe but the elbow has that flange inside and it won't go into the top so I assume I need a compression elbow-reducer to fit it. Other than that, I'm happy so far, cheers Nick.

 

Edit. Actually just checked and the Floplast compression elbow doesn't have that internal flange like the McAlpine does.
