primary ventilated stack

[BOBBOB]

Hello all,
On a two story building, can the stack pipe exit the roof near the eaves, or must it exit near the ridge to work effectively?

Any help much appreciated,
BOBBOB

So long as it is over a metre above an opening window its okay.

You can check all the positions in the Bldg Regs drainage document H on line version free from government planning portal.
