Override Stem Broken
Spare Part: # 2705-CAP
If the override stem is broken, replace the control cover. An indication of a broken stem is that the valve
will not shut off in fault (or when power is removed), while the stem is in Normal position. This is
determined when the valve is disassembled and no foreign object was found that would force open the
diaphragm.
Check Valve/Remove Piston
Tools Required: 1 3/16” box wrench to remove from unit, retainer ring puller, ¼ inch flat nose screwdriver
Spare Part: Check Valve #2081

2. Gently push the piston (water flow OUT side) with the screwdriver until dislodged. The O-ring
remains in place. Only the spring and the piston are removed. Clean with soap and water.
3. Check if the O-ring needs replacement.
4. Insert the spring over the piston and insert them into return port.
5. Replace the retainer ring.
6. Test to confirm that the unit is operational. If there are problems, contact the Service Department
at Rocon, LLC.
