We just purchased a house that has had a second kitchen added. The doouble kitchen sink does not appear to have/be connected to a vent and makes a gurgling noise after the faucet/water is shut off. Is it the lack of a vent that is causing the problem? Is there a silencer device that I can add/install in place of a vent? If so, where do I get it, what is it called and how do I install it? If not, is there another solution. If it is not a vent problem then what else could it be?
