Stink pipe loft connection - is this right?

[Scarletpimpofnel]

For some reason architects think it's a good idea to have stink pipes inside the house nowadays taking up space and inaccessible, one of mine comes into the roof space and fortunately connects through the roof with the connector below.

Where the black pipe connects into the grey pipe it is a loose fit but reasonably secure, i.e. there is movement there, can be rattled around a bit, but it doesn't just fall out.

My question is, is that sort of "fit" normal? Or should the fit be rock solid? It feels like there is one single "O" ring type seal rather than multiple??

If you have to ask . . .
It’s shoddy at best , maybe acceptable for extract duct not for soil and vent

[Little Lofty]

Probably put the vent tile in the wrong place, no other need for the bend.

The connection should be airtight, otherwise it’s not doing its job.

Yeah, why do architects locate SVPs internally?……





Oh!…..

Precisely proves my point. Those are all readily accessible for maintenance or adding /removing pipes not boxed in internally.

Plus any gases are outside the house… some architects terminate stink pipes in the loft space with unreliable one way valves. Bonkers.

I have an AAV concealed in my bathroom. Fitted in 2005, still works fine. No ugly boxing in the corner, no hole in the roof which had started to leak.

Because it looks like a pipe of st on the side of your house? Seems a particular British thing

Looking at your ancient membrane, that’s a retrofit which is reasonably ok.

I think it actually disproves your point. Although potentially more accessible - external soil pipes like those pictured look awful.
If it is possible to fit them internally then having them stuck on the external wall is bonkers !

Was thinking the same. They usually straight line through the roof.

That elevation wouldn’t exactly be a clean look if you took the soil pipe away. To my mind it looks worse as it’s white.

Ours is at the side of the house and I can’t say I’ve ever given it any thought. I only noticed recently that the identical houses across the road have theirs internal.

[James6112]

Easily fixed with some gaffer tape!

[alfabeat]

I'm another one for having the soil pipe mounted externally. I very much favour access for maintenance and repairs over aesthetics! Same with shower trays. If I can't get easy access underneath it to the trap, then I'm not interested.

I suppose it comes from always having lived in old houses, which always need maintenance, which I tend to do myself.

Those pipes look crap on the outside.

Thankfully ours are internal vented properly through the loft, although ours isn’t a crappy new build.

What is the need for the vent anyway? My 1970's house has neither a pipe on the outside (is located within the walls of the house), nor a vent in the loft. It's been like that for over 50 years and yet to explode due to build up of sewer gasses.

They do. And if it's working it makes no difference.
If there's a problem though I'd rather have an accessible pipe of st outside than a hidden one inside.

Its not just for gasses.
