How to unclog a sink (and save $200)

It is embarrassing but a few years ago I paid $200 for a plumbing repair that took the plumber 3 minutes to do. He felt bad charging me but he had to make a night time / Holiday visit and $200 was the minimum charge. Today I look everything up on YouTube or Google. Below is the answer to my then problem. Maybe this will save someone out there some money.
 

The most common types of pipe leaks occur under kitchen or bathroom sinks. These tend to involve either a worn out washer or a loose or broken compression nut that's sealing it. To fix these, first you'll need to turn the water off to the sink. Some sinks have a shut off valve right near the sink itself, but others may be as far away as the basement. You'll have to follow the pipes depending on your house. Check out this guide for more info.

Once the water's off, place a bucket underneath the pipe, and twist off the compression nuts (the big, white pieces you can unscrew). You can take this opportunity to rinse out the curved pipe (called a P-trap), which can get pretty grody by design. Once you've replaced the washer (or the entire P-trap if necessary), you can screw it back in and turn the water back on.
