The new sink is deeper so the Mini vent does not fit.Can I use a adjustable pipe( the one with extendable size) and install the vent a little lower ? Does it have to be upright? Thanks Roochu Hi

Venting usually has nothing to do with how well a drain functions. Instead its function is to protect the water seal of the trap from being siphoned at the end of a vigorous drainage cycle. A toilet is actually a unvented drain. First the drain doesn't flow well but then it picks up speed as the weight of the water falling pulls the water out, then it gulps air at the finish. That is how an unvented drain acts. I would suggest looking at other causes. Lack of a vent can become apparent when there is a clog in the line as the pipe is filling with water and the air has no place to go but a Studor or AAV will not help there because it only lets air in and not out. Cleaning the line would help. If you have a grid strainer and a sink without an overflow air can be caught between the grid strainer and the water in the p-trap slowing things down. This is just the nature of the beast when it comes to grid strainers installed on sinks with no overflow. Sometimes drilling out the holes in the grid slightly larger can help. Getting rid of the grid strainer and going with a lift and turn drain can help too. The same thing can happen with a pop up drain on a sink without an overflow. Sometimes raising the pop up as high as it can open will help. If you have a pop up you can remove it and see how it drains with the pop up stopper to see it it is the problem. If these don't help I would suggest taking a digital picture of the drain pipes under the sink and sending them to Wethead Media by using the "contact us" button and they will share the picture with me. You may have done something wrong with the drain pipes that is causing the slow drainage. Not to worry we'll help you get things working right... Let us know how you make out with this. It is not a venting problem, there are probably 25% of the drains in the US not vented and they drain fine. Don,

At times the sink drains slow. The distance from the sink bottom to the water in the drain line trap is approx 12" with a total drain line running length of about 20". I feel that this 12" (20 total) distance is forming an air trap between the drain line trap and the sink. The Studor Valve lets air into the line, I think I need a valve that will vent the trapped air out of the line. I would install this valve just above the water level in the trap and allow the air above it to be vented when water is dumped into the sink. The valve would also have to have a check valve operation in case the main drain line were to clog and back water up into the sink Your thoughts about this is appreciated.
