What it does and why you need it Functions as a oneway check valve: Allows water to flow forward while closing to block reverse flow. Solves crosscontamination risks: Useful where hose attachments, outdoor faucets, or branch lines could otherwise allow water to flow back into supply lines. Reduces system risk: Adds an inexpensive layer of protection for appliances and potable water lines by preventing accidental backflow. Key attributes Size: 1/2 inch — fits 1/2 inch threaded connections and standard plumbing runs that accept that size. Material: Copper — robust metal commonly used in plumbing components. Connection type: Threaded — designed for screwin installation with matching threaded fittings. Functionality: Backflow prevention via builtin check valve mechanism. Durability: Constructed to withstand routine residential and light commercial plumbing conditions. Typical use cases Outdoor faucets and irrigation: Install on hose bibs or irrigation branch lines to stop lawn treatments, pond water, or garden runoff from flowing back into household supply lines. Appliance and equipment protection: Use inline on water supply lines to appliances (washers, pressure washers, water softeners) to reduce the risk of backflowrelated damage or contamination. Branch and fixture isolation: Place on secondary lines or temporary connections where a oneway flow is required to protect the main system.
