40mm Basin Waste - Threaded to Compression

[primetime]

Essentially will a 40mm compression fitting be suitable for a 40mm threaded waste.

I'd like to (have to) use a bottle trap for the basin due to space constraints. The trap can't reside inside the wall hung vanity so I'll need to extend the waste to below. I can't easily see how to go to 40mm threaded waste and then extend the pipe approx. 200mm to a bottle trap before running horizontally.

I could use a P trap but this would also need to be below the vanity.

Thanks.

No there is a dedicated fitting for it. You need a McAlpine T29-LN as shown here:

Just use one of these

Having a long extension before the trap isn't a good idea

One of these before the trap if it's under basin, straight along to the back, 90 degree bend down into the HEPvO or straight trap -

Thanks guys. I can't get to the back so it will have to be straight down. Phill, do you have a screwfix number? That link doesn't work for me at the moment. I think I might be able to use a pedestal trap.
