Do I Need a Vacuum Breaker on My Hose Bib? Understanding the Importance and Benefits
A vacuum breaker is needed on a hose bib to prevent backflow or siphoning of water from the irrigation system back into the main water supply. This can occur if there is a sudden drop in water pressure in the main supply line. A vacuum breaker allows air to flow into the system, breaking the vacuum and preventing contaminated water from flowing back. It is important for health and safety purposes to install a vacuum breaker on your hose bib.
