NOTICE
Use care when separating the valve, so the
spring and poppet don’t fall free.
NOTICE
Remove the O-ring using a brass, or plastic pick
only. The use of steel picks or screw drivers
could scratch the seat, causing the valve to
leak.
NOTICE
If the body (4), spring (3), and poppet/spring
housing (2), are clean and free of corrosion,
cleaning will not be necessary, and simply
lubricating and installing the new O-ring, is all
that is required. Skip steps 7 and 8 and
continue to step 9.
