Insane in the Main Drain

09 Apr

First, to Cyprus Hill: sorry about the title of the post . . .

After the mechanical went in, the plumbing drain lines were installed. Of the plumbing components, these are the largest, so they needed to be routed after the large AC vents, but before the smaller-diameter plumbing supply lines.

As noted in earlier posts, the 2×6 wall of the powder room serves as a house infrastructure superhighway – there’s going to be a lot going through here. Below is the starting point of drain lines (and associated drain vent lines) being routed from various bays between joists on the second floor, through the bulkhead, down the powder room wall; this culminates in a complex of piping shown at the end of the post:

The powder room itself gets prepped for installation of new fixtures. You can see the hole in the subfloor to the north of the old fixture for old powder room orientation (https://wolfestreetproject.com/2012/03/31/transforming-the-first-floor-goals-and-design-plans/).

Plumbing rough-in begins in the master bath and guest bath. This is a view from the latter, facing south. The two bathrooms will share the drain and supply lines that emerge from the first floor between the shared wall:

A view of the drain line plumbing rough-in from the master bath:

This is the utility closet on the second floor. In addition to the air handler, this area will also house a stacked, front-loading washer and dryer, so drain lines are also needed here:

Below, more progress has been made on both the drain and supply plumbing for the second-floor bathrooms:

Rough-in of plumbing for the wet bar has been complete at this stage (ignore the crazy array of electrical lines to the right – future post, eh).

And, plumbing rough-in for the kitchen sink (this is directly below the south windows on the first floor):

Powder room walls are getting filled up. Lots of stuff routed through this area at this point:

Down in the basement, these drain lines all terminate in a plumbing stack towards the south end of the house:

After the plumbing was completed, the guys tested the system by inflating a service balloon in the clean out port of the plumbing stack (the yellow item below). Our plumber rocks the house. No leaks on the first take (plus, totally elegant routing of both drain and supply lines, as you’ll see in future posts).
