Maintenance Instructions
Servicing the First and Second Check Valves
NOTE: Before servicing be certain water is turned off or shutoff valves are closed
1. After removing the cover, remove the retainer for the body bore. The check valve
modules can now be removed from the valve by hand or with a screwdriver.
Note: For Series 2000B sizes
check modules are not interchangeable. The heavier spring and smaller diameter seat
belong with the first check module.
2. The check seats are attached to the cage with a bayonet type locking
arrangement. Holding the cage in one hand, push the seat inward and rotate
clockwise against the cage. The seat, cage, spring and disc assembly are now
individual components.
3. The disc assembly may now be cleaned and reassembled or, depending on its
condition, it may be discarded and replaced with a new assembly from the repair
kit. O-rings should be cleaned or replaced as necessary.
4. Reassemble the check valve module in the reverse order. Check modules are
installed in the valve body with the seats facing the valve inlet. The modules must
be securely in place before the retainer can be replaced. On the
retainer may have to be tilted slightly into place. Replace cover.
