New soil stack to toilet connection

[Adrian_P]

Hi. I'm installing a new soil stack for a new upstairs bathroom. For the toilet, where the 110mm pipe comes through the wall to outside, which pipe fitting do I use? It has to come out and then across to the soil stack, but all the branches and bends are 92.5 or 87.5 degrees but surely it needs to be 90? Also, do I need an access point at this fitting?
Thanks

Whichever gets you closer to the wall generally, iirc I use 92.5 degrees, it might be that 90 degrees is too tight?

Hi. Thanks. But surely the pipe will come through the wall at an angle?

No, can be as level as you want it, but recommend a slight fall towards the elbow. I think you’re thinking about it differently. The angles refer some to the radius of the bend.

Thanks. The angles can be confusing. I.e. How/where they are measured?

You can actually get 90 degree bends too https://www.wavin.com/en-gb/catalog...smaSoil-vent/OsmaS-PVCU-Bend-90deg-BK-110-DSW

Here’s an example of how they’re measured Brett Martin 110mm 112 1/2º Single Socket Bend (BS421) Black - https://condell-ltd.com/brett-martin-110mm-112-1-2-single-socket-bend-bs421-black?gclid=Cj0KCQiAgP6PBhDmARIsAPWMq6lsw6WttgVYNZ9qKYetEXxjm2YE4af8asioigcLoANEIXSKmJwLBdsaAkuhEALw_wcB
