The vertical orientation suits installations where the pipe run is configured for upward flow, and the brass body provides reliable corrosion resistance in potable water and general plumbing service. At a half-inch pipe size, this valve fits common residential and light commercial branch lines. Licensed plumbers and pipefitters install this valve where backflow prevention is required without the footprint of a full backflow preventer assembly.\u003c\/p\u003e\u003cp\u003eThis check valve is suited for residential and light commercial plumbing systems, including water supply lines, HVAC hydronic circuits, and general fluid-handling applications that require a compact, inline backflow prevention solution. The threaded end connections allow direct installation into standard half-inch threaded pipe configurations. The vertical check design is particularly appropriate for riser and supply applications where flow direction is consistently upward.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass body construction for corrosion resistance in water service\u003c\/li\u003e\n\u003cli\u003eVertical check configuration supports upward-flow installations\u003c\/li\u003e\n\u003cli\u003eThreaded end connections for straightforward installation into standard pipe\u003c\/li\u003e\n\u003cli\u003eHalf-inch pipe size fits common residential and light commercial branch lines\u003c\/li\u003e\n\u003cli\u003eCompact design suits tight plumbing spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install check valve for half-inch threaded plumbing systems requiring vertical backflow prevention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure completely before removing any existing valve or fitting. Ensure the flow-direction arrow on the valve body is aligned with the intended flow direction before making up threaded connections. Use appropriate thread sealant or PTFE tape on all threaded joints and inspect for leaks after restoring system pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Vertical Check\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 32888013049\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LEGEND VALVE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101-304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51233708179762,"sku":"101-304","price":25.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307611811.jpg?v=1780107295","url":"https:\/\/voomisupply.com\/products\/legend-valve-101-304-brass-vertical-check-valve-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
