"Bubbles" and "Gurgles". They are both indicters that something's going on in your drainage system.
A "bubble" indicates a clogged line while a "gurgle" indicates a blocked vent. Let me explain. When you flush the discharge drains down the pipe until it hits a partial clog. Then it rebounds back sending a "bubble" of air ahead of it. When you flush a toilet or drain a bathtub a suction is created by the water rushing down the pipe. This suction is relieved by a open pipe that runs to the outside called a vent. When a vent's stopped up the suction has to relieve itself somewhere, in this case your sink. The noise you hear is the air being pulled through the trap by suction, (gurgle).

The solution would be to snake the kitchen roof vent out. Put out enough cable to get to the base and about 15 feet more. Good luck, Tom
