An air admittance valve that includes a base, a flow control member, a diaphragm, and a cap. The base is open at its ends and includes an interior, an exterior, and a sidewall with at least a first port in the sidewall. The flow control member extends transverse across the interior of the base and includes a cavity aligned and in communication with the first port. The flow control member includes a central opening in the top side that is in communication with the cavity. The cap is selectively connected to the base and includes one or more openings in a sidewall that permit fluid to flow into the cavity. The diaphragm prevents a flow of fluid from the interior of the base into the cavity and permits a flow of fluid from the cavity of the flow control member into the interior of the base.
