Installation Instructions
In addition to protection from freezing, the anti-siphon protects
against possible back siphonage into the water supply system.
Provides a year round supply of outside water without fear of
pipes freezing and bursting.
NOTICE
Hose must be removed to allow water to drain to prevent
freezing.
NOTICE
A. Hose end must be installed sufficiently lower than seat end
to allow for proper drainage.
B. Open valve before heating seat end for solder connection
to avoid burning the rubber seat washer.
The frost-proof sill cock assures no-freeze operation because
the valve mechanism shuts off water inside the building. If
building will be unheated for any length of time, all water lines
should be drained and plumbing fixtures winterized.
A plastic siding wedge is provided to compensate for lap sid-
ing installations. Slip the wedge between
frost-proof flange and siding to form
an attractive finish and solid base for
mounting.
Secure sill cock flange with two #8 or #10
ovalhead wood screws (of proper length)
or with appropriate masonry hardware.
SIDING WEDGE
Installer – For PEX Connections:

F1807-04 PEX end specifications.
