Replace the Vacuum Breaker

Close the control stop valve (refer to the "Control Stop Valve
Operation" section).
NOTE: If the unit has not flushed since the stop valve was closed,
the inlet arm may still be pressurized. Use the manual flush button
to release pressure.
Use a large adjustable wrench to loosen the large tube nut at the
base of the valve body. Let the tube nut slide down the tailpiece.
Gently rotate the top of the valve body away from you while
pulling the top of the tailpiece toward you to separate the
tailpiece from the valve body. The vacuum breaker should now
be exposed for removal.
Remove the loose fiber washer and vacuum breaker from the
tailpiece. Discard both the fiber washer and vacuum breaker.
Install a new vacuum breaker into the tailpiece and place a new
fiber washer on the top of the vacuum breaker.
Gently rotate the tailpiece and valve body back together until the
large tube nut can be threaded onto the bottom of the valve body.
Tighten the large tube nut with a large adjustable wrench.
Open the control stop valve (refer to the "Control Stop Valve
Operation" section).
Verify that the valve functions correctly.
