Thread: this can't be right

Can anyone make heads or tails out of this drain pipe setup at the laundry.... there's no vent nearby. I just can't imagine this is anywhere close to right.

That type of system is usually used on island sinks where there isn't a way to install a vent into a wall.

In the picture I really don't know why they had to install a loop vent there! It looks like the wall is an exterior wall.

Yep.... exterior wall. I always thought there had to be an air admittance valve on the island installs but now that you mention it I guess I've seen some without.

Thanks....

You've heard of the hartford loop? Well that's the Oregon loop.

You nailed it Nick.... it's a PERFECT representation of our local government.

Very creative! Good plumbing practice requires maximum use of fittings and pipe as well as labor to maximize the hours billed. Must have been a Union job.

That is a strange sight to see! I wish I could work on that dryer vent though!
