Chase wall for plumbing

[Elovia]

Hi Bob ... the solution may just be a "forehead slapper". Consider using the break wall tool on your custom double wall on either side of the north side wall, and then simply reverse layers for the short segment of your custom double wall so that the main layer is toward the connecting wall. Any potential wall texture issues can be solved as David showed in his earlier video by either the Room Specification dialog or an individual Wall Specification dialog.

Hope this helps.
