First time poster and newbie DIYer so please limit jargon :-)
We are extending our old downstairs shower/toilet room into the adjacent hallway to make a utility room with toilet and basin. I'm struggling to figure out the best way to connect the various wastes to the original soil pipe and seeking opinions. Please see photos.
Old arrangement from Left to Right: Shower, pedestal basin, toilet.
New arrangement from Left to Right: Basin (vanity), toilet, washing machine and heat pump dryer (which I will connect to appliance J trap with washing machine)
The bathroom above has a connection into this stack at a point that I can't see or easily access.
My main questions are: What kind of pipe do I need to connect to the orange 110m stack connector thing? It looks likes solvent weld so will I need to replace the orange thing? The stack pipe that comes above the floorboards - how best to bring that below the floor and cap off?
