Drip Irrigation backflow prevention

Irrigation systems make watering lawns and gardens easier and save time. It's important to protect public drinking water lines by installing an approved backflow prevention assembly on any irrigation systems. A backflow assembly prevents back siphoning of non-potable water into the water lines and should always be used when applying fertilizer. Having a backflow device helps to protect the health of your household, neighborhood and community. The drip store has two models one with hose thread and one with pipe thread. Backflow Preventers, when used, are the first item in your line after your faucet (hose bib).
