Sorry Nick, you've lost me now. You're now saying both toilets can't share the same horizontal pipe? If so, how will have space to run 2 individual 110mm pipes to the SVP, especially as they would be connecting at the same side?

@Nickfromwales Sorry Nick, you’ve lost me now. You’re now saying both toilets can’t share the same horizontal pipe? If so, how will I have space to run 2 individual 110mm pipes to the SVP, especially as they would be connecting at the same side?

Hi Nick. Thanks again. I think I understand you. I have thrown a rough sketch together to ensure I understand. 90° turn in main bathroom to start the horizontal pipe. Horizontal pipe remains straight, through the wall, to the SVP, with the en-suite toilet connecting via a Y Branch connector? Is that right? Obviously maintaining a fall on the horizontal pipe. Regarding toilet type, attached is what we’re going with for the en-suite. Main bathroom is undecided, but likely to be a freestanding toilet.

Hi Nick, thanks for your reassurance. How exactly will it work? Will I extend the horizontal soil pipe through the wall into the other bathroom, and then have the second toilet connect into it? Are there issues when connecting 2 toilets to the same horizontal pipe?

Hi all. First time poster. Currently renovating our 4 bed house, built in 1988. We’ve just finalised our architect plans for our extension and downstairs reconfiguration. As part of our plan, we need to get rid of one of our SVP’s, the one that currently serves the main bathroom. The plan is to then have both the main bathroom and en-suite, use the existing SVP in the en-suite. Although our architect says it will be fine, I have serious concerns that this just won’t be possible, due to the distances involved and due to everything coming from the same side. Please can I seek the advice of you wonderful professionals so I can decide a way forward. I’ve attached the architect plans for proposed ground floor and 1st floor. Screenshot of proposed bathroom layouts has existing SVP’s marked in red, including showing which one is going. I’ve also attached a photo of the en-suite now that it’s been ripped out so you can see the SVP that’s staying. Thanks.
