Ventilation

[sparky999]

Evening

Been told by a builder to install a couple of fans in a few bathrooms, he has been told by BC that you can vent them out into the main soil stack.

I have never heard of this before any of you or is it aload of old tosh?

Cheers

Blimey never heard that one before, what about the smell of travelling into the fan's ducting and entering the room .

I'd say that was a load of ballcocks.

I look after some offices where the toilet fans are ducted into a 6" rising soil pipe but its for the fans only, not the same as the toilet waste .

Not a good idea any reason for not wanting to vent in a normal way through roof or wall or soffit?

This isn't an issue with 7671 so any certs signed will not be relevent. I bet someone has got the wrong end of the soil pipe here and thats not what the BCO means. Suggest you confirm that with them as if it needs to be fixed, they may want you guys to pay to fix it.

I have a similar sceario in an attic conversion, and stack pipe has been approved for ventilation - obviously at a point above the tide mark.

So the point of u-bends in toilets and sinks is to stop the bad smells comming back in and then you go and hook up a direct link to one. Seems really dumb to me.

Is that not for ventilation of the soil pipe? Not for the room?

Might work if You had a one way valve set up between the fan and the soil pipe in the hope it would keep out nasty smells from the room needing ventilation . If building control allow venting via the soil pipe then there has to be a satisfactory way .

......."when the s..t hits the fan " .... ROTFWL why didn't I think of that ? :Applaud

Thought that the opening at the top of the soil stack had to be above the highest opening window in building so that any methane gas rising up the stack can be vented to the atmosphere above building, if connected the outlet of the fan to the stack methane gas could enter building when fans are off.
