How about this setup?

The garage was converted into a mother in law unit. The waste line you see is attached to the washing machine. Besides the obvious of the gray water emptying into the city runoff(running into a tight line), what about that air vent?

Is that an AAV installed outside?

[Robert Jones]

Indeed

[resqman]

Is there a P trap for the washer? What about water freezing in the exposed pipe. What about PVC not rated for direct exposure to sunlight? How about improper slope of the pipe and lack of support for the vertical pipe.

Why install an air vent when it can be directly vented to the exterior?

This is definitily DIY and does not meet any plumbing standard. Condem the entire thing and replace by a licensed plumber.

[Robert Jones]

Agreed. We had a good laugh on site. What you see there is directly from the washing machine. No P trap.

You gotta love some of the DIY work we all see in this business.

Well isn't the downspout doubling as the vent. I see no need for the AAV.[:-taped]

Nice elbows.....I guess the proper sweep might have made it look funny......
