The Automatic Flush Valve is a self-cleaning device designed to purge debris from your drip irrigation lines at the start and end of every watering cycle. By installing this valve at the end of your mainline or drip tape rows, you allow a small burst of water to flush out fine sediment before the system pressurizes and seals. This simple addition works in tandem with your system filter to prevent clogged emitters and extend the life of your setup.
Available in both Hose Thread (VFH) and Pipe Thread (VFP) configurations, these are essential irrigation fittings for low-maintenance systems. Whether you are running a home garden on standard poly tubing or a commercial field, adding a flush valve ensures that dirt settling in the lines is expelled automatically, saving you the manual labor of opening end caps.
Choose the correct thread type for your system.
