Drain pipes

All drain pipes (DWV) are finally connected and tested. Test plugs are still in, and the required 10-foot head (almost a 20-footer in my case) is still holding after two hours.

The washer outlet box at each location has a Watts Intelliflow. It's a safety device that opens the water valves only if the washer is operating. The washer cord plugs into the device (dark square in the middle) and the device plugs into a standard wall outlet. There's also a leak sensor (not shown).

Underfloor, it looks like a maze of ABS, copper (original to the house) and cast iron waste pipes. The savvy plumber installed dedicated test tees and inserted inflatable plugs -- nicer than testing through cleanout wyes, he says. No "debris" flying back at your face upon retrieval.

Still needs some support straps...
