Hi all,
What is this hose's purpose? It connects above the P-trap on my bathroom sink and runs into a wall facing the outside. It's on only one of the two sinks in the master bath. My wife says when it's cold she can hear what sounds like wind coming from the sink drain. This sink is on the third floor. I attached a picture below. Any ideas?
