1. After removing the cover screw, the check comes out
with the cover.
2. Holding the check Valve module in both hands, rotate
the assembly
1
⁄4 turn. This will disengage the disc and
spring assembly into individual components. The disc
assembly may be cleaned or replaced. O-rings should
be cleaned or replaced as necessary and lightly greased
with the FDA approved silicon grease. Reassemble
the check valve module in the reverse order.
NOTE: The springs of the rst and second check valves
are interchangeable.
(Before servicing, be certain water is turned off or
shutoff valves are closed)
