Sounds like you are looking at the gray water Air Admittance Valve(s). When you drain your gray water tank(s) it allows air in the pipe so the water can drain out. The valve is suppose to close when the tank is empty or the water flow is stopped.
If you ever get a sewer smell from under your sink it normally means that the valve is sticking open.
