Frost-proof sillcock with anti-siphon protection
This quarter-turn sillcock uses a 10-inch stem to keep the shut-off valve inside the heated envelope of a building, preventing freeze damage during cold weather. The chrome-plated brass body resists corrosion while the integrated anti-siphon device stops back-flow contamination of the potable water supply. It is designed for residential and light-commercial outdoor water connections.
Capacity and headroom for pressure and temperature
Rated to a maximum pressure of 125 psi, the valve handles normal municipal water pressure with margin to spare. The 1/2-inch inlet accepts either solder cup or male NPT connections for flexible installation. Aluminum quarter-turn handle operation provides quick on-off control without the gradual wear of multi-turn stems.
Standards compliance and installation limits
The unit meets ANSI B1.20.1, ANSI B16.18, ASME A112.18.1/CSA B125.1 and ASSE 1019 for plumbing safety and back-flow prevention. Threaded connections follow ANSI B1.20.7 for reliable sealing. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item
Will the 1/2 in inlet on this 10 in sillcock thread directly onto my existing copper supply line?
The inlet accepts either a 1/2 in solder cup or male NPT connection, so it can be sweated onto copper or threaded onto a 1/2 in female fitting.
How can I verify the anti-siphon function is working after I install the sillcock?
With the quarter-turn handle open, shut off the interior supply valve; if water stops flowing and no vacuum draws contaminants back, the ASSE 1019 vacuum breaker is operating correctly.
Does the box include a handle or do I need to buy one separately?
The aluminum quarter-turn handle is factory-fitted to the chrome-plated brass body, so no separate handle purchase is required.
