I’m working on a house where the owner wants to move their laundry facility into their basement. This involved quite a bit of plumbing work. However, the outcome was outstanding. By building everything into the wall the owner can push their stackable washer and dryer flat. My plumber did a beautiful job with his craft. In addition, we made sure to insulate the dryer vent as it will travel through a cold attic. No future problems with condensation condensation! See photos below.

Absolutely beautiful plumbing work!
