One very common plumbing problem is a clogged kitchen sink. Since sinks get so much use they can easily become clogged. Fortunately clearing a clogged kitchen sink can be easy if you know what to do.
There are a maximum of four steps to clearing a kitchen sink clog. I usually suggest starting with a plunger because many clogs can be easily cleared this way. The reason to not use drain cleaner first is because if it doesn't work you will end up disconnecting the pipes with all of that drain cleaner in them. And what a mess that is!
