The vent should terminate above the highest window with a cage on top.
An
AAV can be used or fit Hepworth HepVo traps in the basin, bath and

These dry HepVo traps are AAV's themselves, so eliminating the need for
one large AAV.

Eco homes do like to have penetrations of the building fabric,
especially
metal such as flues and overflow pipes. HepVo's eliminate the need for
a
soil pipe to penetrate the building fabric.

How does that vent +ve pressure?
It doesn't. Pure drivel, as usual.

This man is a lunatic.
