4. Inspect the NRS Valve
A. Remove actuator assembly from NRS valve body.
B. Use a straight screwdriver to rotate the valve inside the NRS valve body. The valve should freely rotate from the open to close positions for 90 degrees of rotation.

Repair: Replace the NRS valve body and install the actuator assembly that was previously removed.
