Downstairs WC with concrete floor, current manifold takes the outlet from the toilet and 32mm from basin.

I will be ripping everything out back to the blockwork and want fit a wall hung toilet ideally without having to build a deep false wall.

The current manifold position would mean the false wall would need to be around 30cm deep from the existing wall, I'd prefer to have it shallower.

Something like this would be ideal (https://www.screwfix.com/p/40832), however I am unsure about the air admittance valve.

Any thoughts?
