I would like to rotate my WC by 90° to increase the space in front of it (currently 14"). This would need the soil stack to be moved 2ft to the left and then 2ft along the side wall. I am not too bothered about 'looks', but I DONT want to dig up & re-site the existing stack. Would it be feasable to run a 3½" pipe from the loo to the soil stack? would I need special adapters?
TIA
Dave
