I need to move a toilet about 1.5m to make way for a walk in shower. The current soil pipe and vent take a tortuous route due to a previous house extension.
I can disconnect the existing toilet waste, but then need to add in about a 1.2m horizontal for the new toilet location along with either a 3 way branch or Y branch into the soil pipe and vent. See attached drawing. I just want to confirm if the arrangement will work? I can't seem to find this scenario anywhere online to confirm. Thanks
