Probably required where potable water is used for irrigation. If there is a loss of pressure or negative pressure in the main line, this device prevents water from being sucked back out the irrigation lines.
What type of backflow valve is installed on the potable lines going into the house? I wonder why that same valve is not used for irrigation lines.
