Hi all. I'm looking to replace my current 110mm cast iron vent/soil stack with a plastic one.
However there is no toilet connection to it, it exists purely as a vent and my downstairs toilet outlets directly into the foul drain below ground level. Was wondering if I could reduce the size of the stack, and what to, and still comply with regs. I'm fairly sure I can but would like to clarify a minimum size.
Many thanks.[/list]
