So I picked up this "AAV kit" from home depot today to finally fix my sinks drain problem. My house is a converted garage (mother in law house sorta thing) and the pipes for the kitchen sink never had a roof vent put in, and since the whole place is made of cinder block, its rather hard to put one in so I decided to try a AAV.
its made by "Oatey" and its a "Sure-vent." I have two sinks, both drain to the same pipe, then go into a J-bend, then into straight pipe then down a metal pipe to the sewage. For years this sink would drain horribly slow, and a plumber told me it was because of the lack of venting. So I installed this AAV on the straight pipe between the J-bend and the sewer pipe with a T-fitting, turned on the sink, and checked it and nothing. same as before. I unscrewed the AAV, and as I unscrewed it I could hear the hiss of air rushing into the pipe as I was unscrewing the aav. So I tested the AAV by cupping my hand over the AAV, then putting my mouth to my hand and sucking in, and sure enough the valve opens with the slightest pull of air. So any ideas on why this thing doesn't want to work?
