Bathroom fan vent / Durgo on soil stack

[neilht]

Prob been asked before but:

The soil stack is ventilated through the loft space and into a tile vent on the roof

Can I cut the pipe in the loft space and fit a durgo, then use the tile vent to connect bathroom fans too ( family bathroom and en-suite?

Cheers!

No, (in my opinion). The Vent is there for a reason, and Building regs state the head of the drain must be ventilated. Removing it could open you up to a world of other problems, smells, gurgling traps, and worst case scenario, a redecorated bathroom if someone comes along to clean a nearby sewer and there's a backdraft which cant escape....

Secondly, 2 fans need 2 outlets, or you could have issues with output from one fan reappearing in the other room if weather conditions are wrong.
