B & K ProLine Series 104-823HC Anti-Siphon Sillcock Valve, 1/2 x 3/4 in Connection, MIP x MHT, 125 psi Pressure

ProLine Series Frost Free Anti-Siphon Sillcocks offer an excellent alternative to standard hose bibbs in areas where freezing happens regularly through the year. When installed properly in basements or crawl spaces, the valve is angled down slightly to ensure water drains properly when shut-off so when freezing weather sets in, no water is present to cause bursting. The installed anti-siphon will prevent water from backflowing into the valve upon shut-off.
