Cheater valve for kitchen sink
syrgal

I purchased a home last month for the first time. I went through the house with the inspector. He said there is no venting on the double kitchen sink. He also said i could install a" cheater valve". He said it isn't that hard to do.When i wash dishes in the sink it takes till the next morning for the sink to drain. I went to home depot and purchased a cheater valve abs inline vent and a T pipe( i think that is what it is called). The plumbing is all pvc. the T pipe he gave me is a 1 1/2", it looks bigger than the pvc pipes that are already there. Does anyone know where I can find directions on how to put this vent in. Thank you for any help you may be able to give.

It really sounds to me as if your drain is clogged. Not having a vent will make it glug, or siphon the trap dry, but not take all night to drain. You have a different problem that adding an "air admittance valve" will not cure.

I'm not a fan of AAV vents. They may be to code in your area, but they are inferior to a real vent through the roof.

The previous answer may solve your drain problem. If you have't used a snake before, call a drain plumber, who will do a good job and give you a guaranty for more than a day.
