Hi,
I have recently posted a question about tapping into this drain:
So I have to tie into that drain somewhere lower. The drain that you see in the picture is actually 4 feet off the floor but it takes a 90 degree turn downwards and it's into this vertical part of the drain that I would need to tie in. So my question again is: what's involved? I assume it's cast iron so I would somehow have to drill a hole in the cast iron and attach a 2" pipe. What do I need and where do I start?
Many thanks in advance,
Aaron
