The drain check valve keeps lines from draining when the system is shut off. This saves water, reduces liability, and increases system life. To Replace the Drain Check Valve: Remove the internal assembly from the case. Insert the large, irregular shaped end of the Drain Check Valve assembly into the bottom of the riser. The small circular rubber portion of the Drain Check Valve Assembly will remain outside of the riser. Replace the internal assembly and tighten it to the body.
