Dual Valve Installation
FREEZE VALVE ONLY: Remove
the old ball valve and install the
new ball valve.
NOTE: When the valve is in the
closed position, make sure the
ball weep hole points toward the
showerhead.
A
Install the freeze or scald protection valve at a low
point or where the water will tend to be static or
“dead leg.”
DUAL VALVE INSTALLATION: Make sure the
freeze valve is connected closest to the ball valve.
NOTE: Point the valve(s) downward to allow for
drainage (the flow should be in the direction
shown on the valve’s nameplate
.

IMPORTANT
To prevent an ice patch hazard, Bradley
recommends that discharge from the valve be
directed through a hose or piping to the waste.
Discharge hoses or piping should be short so that
there is no standing water that may freeze.
To prevent restriction in the tube, make sure the
pipe tie straps are snug around the tube and piping
but not overtightened.
