    摘要: A vented drain for recreational vehicles and the like which provides the required venting of sink drains without generally requiring more than one hole through the vehicle wall. The vented drain is substantially a one-piece molded plastic member which connects to the sink drain line within the vehicle and conducts drain fluid through the vehicle wall by a first conduit. A second conduit, either surrounding the first conduit or adjacent thereto, provides a flow path for vent air through the vehicle wall and communicates with a vertically disposed baffle stack within the vehicle to define a flow path for vent air of the required height. This prevents drain fluid flow through the vent and provides a source of vent air to the drain conduit to prevent siphoning of the drain trap. Various embodiments of the basic invention are disclosed.
