The sink in my upstairs bathroom was making a gurgling sound and was not draining correctly.
This video shows how to open the trap and clean a blockage out. Most times in a bathroom sink, the problem is due to hair. If you have a pop-up stopper in the sink, most times that will catch a lot of it, before it goes further down the pipe and gets to be a more serious clog.
So that means anytime you notice a change in how your sink drains, take a look at it immediately, as it could save you a lot of trouble later on down the road.
