[ Ссылка ] - The freezeless Woodford Model 19 outdoor wall faucet is designed and intended for year-round residential irrigation purposes regardless of outside temperature. A patented pressure relief valve (PRV) prevents bursting during freezing temperatures, even if a hose is inadvertently left connected to the faucet. The faucet will still freeze, however it will not rupture. As a result, this product prevents water damage when hose is left on. Woodford Model 19 also contains an integral backflow protection device which protects up to 125 psi of backpressure and therefore does not require an add-on vacuum breaker. - [ Ссылка ]
