I have the attached piping spread over 2 cabinets in the ground level kitchen, I would like the corner cabinet to have a lazy Susan in and the plumbing all in the one sink cabinet.

Can I move the long pipe going to the right down into the basement into the basement ?
Something like in attachment after.jpg


Foil is a drip catcher, it drips when the washing machine is on and the tap is used downstairs and up. All being replaced.

Can I move the long pipe going to the right down into the basement into the basement ? You're going to hafta do better then that. What long pipe? How long? Is it a vent (vertical ) or a drain(horizontal)?

Something like in attachment after.jpg your attachment failed to load. Do you need instructions on how to post attachments? What is it you wish to move? The drain line? The roof vent or both?
Can you repost with more details and perhaps a drawing? Cheers, Tom
