What is a backflow preventer?
A backflow preventer is a device used to protect you and your neighbors’ drinking water from contamination.
How does contamination occur?
Sprinkler systems are plumbed into the same potable water that you drink, thereby creating a potential cross contamination hazard. Contaminated water can end up in your drinking water through back siphonage or back pressure. A backflow device prevents either of these threatening situations from happening.
