When I first heard about backflow preventers, I wasn’t sure why they were necessary. Essentially, a backflow preventer is a device that stops contaminated water from flowing backward into the clean water supply.

There are several types of backflow preventers designed for hoses, such as vacuum breakers, double check valves, and atmospheric vacuum breakers. I found that understanding these types helped me choose the right one based on my water pressure and local plumbing codes.
