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 007 sizes
1
⁄2" - 2" (15-50mm), the seats and
springs of the fi rst and second check modules are not inter-
changeable. The heavier spring and smaller diameter seat
belong with the fi rst check module. Series 007M1 sizes
3
⁄4" - 1"
(20-25mm) and Series 007M2
3
⁄4" (20mm) have interchangeable
seats and springs.
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, for
3
⁄4"
(20mm) Series 007M2 pull apart seat and 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 replace
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
3

size, this retainer may have to be tilted slightly into place.
