Vents are a major component in a home's drainage system. Venting allows water to pass out of the drains easily. Today, houses are vented through the roof. Roof flashing, made from heavy grade rubber, lead or sheet metal holds the vent pipe in place. Another thing to consider is pitch.
This type of drain is rarely used for chest tubes on both sides of. the chest at the same time; rather, the tubes are on the same side of the chest. Typically, this drain is used when one. tube is placed high in the chest to evacuate air, and one tube is placed low in the chest to drain fluid on the same side.
