That is an “S” trap. Improper trap assembly. If it’s also unvented, state that it’s unvented, don’t specify the repair method.

Studor :wink: Regardless, you should call it an AAV.

Take your pick…

  1. There is at least one or more “unvented S-Trap(s)” present. Although common in older homes like this one, they have not been an approved use in plumbing systems for over 20 years. Sometimes they will gurgle when draining water (they’re struggling for air). They can also　dry up and allow sewer gas or odors back into the building. Common methods of repair are properly venting them outside, or if that is not possible - changing any of them to a “P-trap” with an AAV (auto-vent) if your jurisdiction allows it. We recommend you consider changing these.

Although common in older homes, this home is newer and in our opinion this indicates a handyman installation VERSUS performed by a competent plumber.
