Hi all, new here.
I’m having the back of my house rendered and want to tidy up the waste pipe work before and after.
Currently both 1st floor sink and bathroom waste pipes go into a cast iron hopper and from there down to the gully in 2 1/2” caste iron? This is close enough to the new (ish) plastic 110mm soil stack. Can I run the sink and bath wastes to the soils stack and attach with strap bosses or use the existing in line boss
(same level as the loo waste) ? I could then do away with the hopper and down pipe. Hope this complies with current regs. Cheers. Lozza.
