The drain metal pipes are usually coated and galvanized because of the hard water.
The sink gurgles when the water drains because air is being pushed through the pipes along with the water, creating a bubbling or gurgling sound.
Water pipes can vibrate when the water is turned off due to a phenomenon called water hammer. This occurs when the flow of water is suddenly stopped, causing a pressure surge that can create vibrations in the pipes.

Pipes knock when water is turned on due to a phenomenon called water hammer. This happens when the flow of water is suddenly stopped or redirected, causing a shockwave that creates vibrations in the pipes, resulting in the knocking sound.
Pipes rattle when water is turned off due to a phenomenon called water hammer. This happens when the sudden stop of water flow creates a pressure surge that causes the pipes to vibrate and make noise.
The shower gurgles because the water is going down the pipes.
Singing water pipes can be caused by air that is trapped in the pipes. The air can cause a whistling or singing sound, or it can cause the pipes to knock or rattle.
I had a water pipe break on a Friday afternoon, when I was expecting company the next day. I called Drains N Pipes and they were able to come out and repair my pipe immediately. The plumber they sent was very nice and had my pipes repaired and was out the door in under an hour. The rate they charged was fair and I am very happy with their service. I will be recommending Drains N Pipes to all my friends.
