Looking for some advice on re-routing the kitchen waste pipes.
Piccy here:
I was planning to connect the DW to the sink trap via a spigot. The WM is staying where it is as I can't see an alternative to running this pipe under the floorboards as the back door is between it and the drain.
But what would be the preferred solution for running the pipe from the sink to the drain? Is it better to have three meters of pipe on the exterior wall (unsightly but easier access, decent slope), or behind the units (hidden but inaccessible, decent slope) or under the floorboards (hidden, inaccessible, shallower slope)?
How best to connect the sink and WM runs? And do they need additional venting?
I've always used push fit in the past but is solvent weld a better option? And do I need to increase the size of the pipe to 50mm?
Thanks in advance for any advice.
