? on the cleanout?

[Richard W. Washington]

this is the kitchen sink cleanout. Any ideas what has been attached to it? 2008 home.

the black rubber hose run's about 4' and then comes out of the ground & is open at the end.

Cheater valve(vent). The black hose is a supply line to keep the P trap filled with water.Weird way of doing it.

[Richard W. Washington]

why on earth would someone do that? i mean, i understand of course that a p trap should have water. Did I miss something at the kitchen sink plumbing?

Richard...that's an air-gap where the black hose enters the PVC. It is possible that is a water softener drain that was never hooked up. Was there a water softener or loop for a future installation of one in the garage?

Be my guess as well, Softener Brine Drain.

or the dishwasher drain.

Agree with an air gap/drain for a softener, disagree with the dishwasher drain... too small, and impractical.
