Hello again

Next problem…… I will be fitting/getting fitted, an upstairs shower room, fitting a new soil pipe down through floor, into cupboard, then under ground floor, out to manhole (which has connections available) in garden. I have to fit a roof tile vent in the upstairs shower room which has a 4” flexi pipe that is reduced to 3.5” at the bottom

My question is …. Would I be able to reduce this any more i.e. to 2” or would that be too little air, as I have a problem with getting a 3.5” pipe to the vent ??
p.s. , from vent to manhole would be about 12m
cheers

I'm confused. :scratch: What is the roof vent tile for.

What pipe do you want to reduce.

sorry,
i need to have a vent for the soil pipe for the wc and stuff, i think ??,
the only way it can be vented is a durgo or a roof vent, the shower room has the roof directly above it so the roof vent was a better option, the roof vent has a 3.5" flexi tail on it, which can be fitted in the slope of the roof, I need to connect the vent to the 4" under shower room floor, it would make life alot easier if i could connect in 2"
or maybe i dont need a vent ?????
does that make sense ??
i think i have confused myself :dunno: i need to lay off the Glen Fiddoch
cheers

Bushmills "Blackbush" is nice.

If you have an SVP elsewhere you could use a durgo.

If the vent is for an extractor then it needs to be 110mm.

the pipe would be inside a wall so im guessing a durgo is not an option,
there would be no other connections, pipe would run from the shower room to manhole, as far as i can see there is no other way to allow air into pipe other than the roof vent or the soil through roof with a tile flashing rubber thing. but i dont have 4" room in walls to put pipe,

You could go to 3" and fit a durgo provided the wall is vented
