Fitting in a new soil stack with little space
Anonymous user 15 March 2024 - 2.36 PM
We are fitting a new soil stack (new upstairs en suite) and building regs have told us we need to have a ‘slow sweeping bend’ at the base attaching to the main run via a Y junction. Problem is, it doesn’t fit! The main run is too close to the foundations so the standard bend you’d normally use sticks out from the house too far to make it feasible. Any suggestions for what to try next? And what constitutes a ‘slow sweeping bend’ according to building regs? TIA.
Are you a tradesperson and able to answer this question?
Your best bet is to contact whoever told you this and ask for their advice as standard ones don't fit.
They will give you a suitable solution that they are happy with.

A slow sweeping bend constitutes either a 15 degree or a 30 degree bend slow and sweeping so the flow after the fastest point is slowed into the main run, to avoid splash back. If you don't have the room to get the required slow sweeping flow you may need think about a back drop manhole. This is for sloping ground or for limited area for required flow. You can get some detailed imagery from Google. Easier explained visually sometimes. Cheers
