This was the perfect answer for my laundry room which was not vented properly in the past. Everything drains smoothly now.

My kitchen sink set up was never vented and it gurgled every time I drained it... As soon as I installed it, it solved everything.

I’m using this as a vent for my potable water IBC tank. Now I can use water from the tank without loosening the entire top cap.

My sink would gurgle when the washer was draining, so I got this drain vent and installed it, and it fixed the problem.

The Oates Air Admittance Valve Kit did the job for me. It was easy to install and came with more than enough extra pieces to fit any configuration under the sink.
