Hello,
After a bit of advice, I need to connect a 40mm shower waste into an existing 3 inch cast iron soil stack serving 3 flats in a large block. Unfortunately i can't replace whole stack for plastic as would change aesthetics of the building plus too may iron joints going straight into the back of it.
Can you get strap on boss big enough to take shower waste. The only thing I can find is a macalpine fitting
BOSS82TCAST-BL 1½"
However it fits into the stack with just a 22mm hole and is therefore only suitable for a condense pipe.
Any thoughts would be greatly appreciated.
The 3" soil pipe only takes waste from kitchen sinks and bathroom wash hand basins currently. The toilets are connected to a 4" stack on the other side which I can't get to.
Thanks in advance
