Gurgling sound under kitchen sink

Whenever we run water in our kitchen sink the drain makes a gurgling sound for about 30 seconds. Our plumber said this was "normal" but we'd like to make it go away. I've read I might need an air admittance valve. Will this fix the problem? Does it just install under the sink somewhere?

Does the piping after the trap go into the wall, or does it do a S-configuration and go through the floor?

It goes into the wall behind the sink. Inside the wall it would only be able to go right or down. We have a basement.

If the drain does not have a vent, what you are hearing is the drain siphoning air out of the trap as the water travels down the pipe.


Or, it could be a clogging issue, but my first thought puts the drain without a vent.

So is an air admittance valve under the sink the way to fix it?

Not sure of plumbing codes in your area. Some do not allow Air Admittance Valves. That would be the way to go though. Good luck.
