Abstract
A drainage component in fluid communication with the fluid supply line includes a drain channel leading to a drain, the drain channel having an inner wall and an outer wall. The inner wall has a sealing surface approximate a three-way elastomeric valve. The elastomeric valve includes a moveable first wall having a first position when the fluid supply is on and a second position when fluid supply is off and a second wall connected to the moveable first wall, the second wall engaging a drain sealing surface when the first wall is in the first position. The elastomeric valve includes an orifice through which fluid may flow. When the pressure of the fluid on the elastomeric element increases, the second wall of the elastomeric valve engages the drain sealing surface. The elastomeric valve is preferably a fluoroelastomer to ensure both flexibility and resistance to a variety of chemical products.
