Hi.
I am having small single story extension. The existing soil stack will exit the new roof pass closely between 2 windows and above eaves. This is also reflected on the drawings.
The builder doing the roof wants to remove the stack and fit an external vent which will be a short distance below windows. I prefer the original stack be left as it is, am I wrong to insist on this, what do building regs prefer?
Grateful for any help .
