1. An apparatus comprising:
a base, the base having a first end, a second end, an interior, and an exterior, the base having a sidewall, the base is open at the first end and the base is open at the second end, the base having at least a first port in the sidewall;
a flow control member, the flow control member extends transverse across the interior of the base, the flow control member having a top side, a bottom side, and a cavity between the top side and the bottom side, wherein the cavity is aligned and in communication with the first port, the flow control member having a central opening in the top side, the central opening being in communication with the cavity, wherein the cavity only communicates with the interior of the base through the central opening in the top side of the flow control member;
a cap, the cap is selectively connected to the first end of the base, the cap having one or more openings in a sidewall, wherein the one or more openings permit fluid to flow from the exterior of the cap into the cavity of the flow control member;
a first standoff that extends from the top side of the flow control member and a second standoff that extends from the top side of the flow control member;
a first guide that extends from a top surface of the first standoff, a second guide that extends from the top surface of the first standoff, a third guide that extends from a top surface of the second standoff, and a fourth guide that extends from the top surface of the second standoff;
a diaphragm, the diaphragm is positioned between the top side of the flow control member and the cap, the diaphragm selectively seals the central opening in the top side of the flow control member; and
wherein the diaphragm prevents a flow of fluid from the interior of the base into the cavity of the flow control member and permits a flow of fluid from the cavity of the flow control member into the interior of the base.
