Know before you buy
Installing the device at least 6 inches above the highest point of your irrigation system ensures it functions correctly as an anti-siphon valve. This height requirement prevents back-siphonage by allowing air to enter the line and break the vacuum if water pressure drops.
No, this product is specifically rated for cold water irrigation use only. Using it with hot water may damage the internal seals and compromise the device's ability to prevent backflow.
Yes, this model features serviceable internal components. If the seals or internal parts degrade due to regular use, you can replace them to maintain the integrity of the backflow prevention without needing to replace the entire brass housing.
This vacuum breaker is designed with 3/4-inch female pipe threads (FPT). While it connects easily to standard outdoor plumbing, you may need a specific adapter if you are connecting it directly to a standard garden hose rather than a threaded pipe.
Yes, the durable brass construction is built to withstand outdoor elements and pressure ratings up to 150 PSI. However, like all irrigation equipment, it should be protected from freezing temperatures during the winter months to prevent cracking.
