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.

The shower gurgles because the water is going down the pipes.
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.
