The valve adjusts in height from 9 inches to 13 inches, allowing a single unit to fit a range of toilet tank configurations without requiring multiple SKUs on the truck. The anti-siphon design prevents backflow from the tank into the supply line, meeting common plumbing code requirements for potable water protection. This is a carded retail-style unit suited for plumbers, maintenance technicians, and experienced DIYers performing toilet tank repairs or full valve replacements.\u003c\/p\u003e\n\u003cp\u003eThis fill valve is intended for use in residential toilet tanks where a height-adjustable, anti-siphon compliant fill valve is required. The adjustable range of 9 to 13 inches makes it compatible with a wide variety of standard two-piece and some one-piece toilet tank depths. It is a common replacement part for aging ballcock-style or fixed-height fill valves and is typically carried as a standard repair stock item.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeight adjusts from 9 inches to 13 inches to fit multiple tank depths\u003c\/li\u003e\n  \u003cli\u003eAnti-siphon design helps meet backflow prevention requirements under common plumbing codes\u003c\/li\u003e\n  \u003cli\u003ePlastic construction resists corrosion in continuous water contact environments\u003c\/li\u003e\n  \u003cli\u003eCarded packaging suitable for retail display or service van inventory\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 30 units, practical for wholesale or supply house purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fill valve for standard residential toilet tanks requiring an adjustable anti-siphon float valve in the 9 to 13 inch height range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified maintenance technician. Shut off the water supply at the angle stop valve below the toilet and flush the tank to drain it before removing the existing fill valve. Follow all applicable local plumbing codes, including IPC and IAPMO standards regarding backflow prevention devices. Do not overtighten the plastic locknut securing the valve to the tank; hand-tight plus a quarter turn is a common practice to avoid cracking the tank porcelain.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustment Range\u003c\/strong\u003e: 9 to 13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-Siphon\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 30 EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22.22 pounds (package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LARSEN SUPPLY CO., INC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 781346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LASCO","offers":[{"title":"Default Title","offer_id":51558906364210,"sku":"781346","price":436.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bdd4098f531b3ccb840b0571445bc0.jpg?v=1786422446","url":"https:\/\/voomisupply.com\/products\/larsen-supply-781346-anti-siphon-toilet-fill-valve-9-13-in","provider":"Voomi Supply","version":"1.0","type":"link"}
