Backflow Actuator Seal Replacement:
There are two parts (12 & 13) on the
backflow actuator that are subject to wear.
Before replacing the seals, the pipeline must
first be depressurized and drained. Next,
remove the backflow assembly from the
valve by turning the Backflow tube (14)
counterclockwise. Disassemble the actuator
as
follows:
•
Remove the Set Screw (18) with an
Allen wrench.
•
Loosen the jam nut (15) and spin it back
until it
’
s just under the T-Handle (17).
Turn the T-Handle fully clockwise (17),
then remove the Setscrew (18), T-
handle (17) and jam nut (15) from the
Backflow rod (16).
•
Remove the rod (16) from the tube (14)
by hand turning it counterclockwise. Do
not use tools that would score or
damage the smooth sealing surface.
•
Using a pick remove the rod wiper (12)
and rod seal (13) from the end of the
backflow tube (14).
•
Inspect and if needed clean the inside of
the backflow tube.
•
Lubricate rod wiper and rod seal with
approved grease and install in the
grooves in the backflow tube.
•
If necessary, clean the backflow rod with
fine emery cloth. Lubricate the non-
threaded portion with approved grease
and thread into the backflow tube being
careful not to damage the rod seal or
wiper.
•
Install jam nut, T- handle and setscrew.
•
Turn T-handle fully counterclockwise.
•
Apply thread sealant to bushing and
carefully thread into valve taking care
not to cross-thread the bushing.
•
