Check Valves

Check valves are a type of valve that allow water and sometimes gasses to flow in only one direction. This prevents water from backing up and reversing in flow. When the water flow is going in one direction the valve opens to let the water pass, but when the water starts backing up the valve will close to stop the water from back-flowing.
