The kit includes an adjustable flush valve, a 3 inch adjustable flapper, a gasket, a toilet wrench, bolts, washers, and nuts — everything needed to restore proper flush function without separate parts sourcing. The flush valve height adjusts up or down to accommodate varying tank depths, and the flapper adjustment allows fine-tuning of water volume per flush. Plumbers and experienced DIYers install this kit during routine toilet maintenance or when addressing poor flush performance and valve wear.\u003c\/p\u003e\n\u003cp\u003eThis repair kit is designed for residential toilet service on high efficiency toilet models with 3 inch flush valves. The adjustable valve height and flapper design make it compatible with a range of tank configurations, reducing the need for model-specific parts inventory. It is well suited for service calls where the existing flush valve or flapper has degraded, causing weak flushes, phantom flushes, or continuous running. The included toilet wrench simplifies removal and reinstallation of the flush valve assembly without additional specialized tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable flush valve height to fit a range of toilet tank sizes\u003c\/li\u003e\n  \u003cli\u003e3 inch adjustable flapper for water volume fine-tuning\u003c\/li\u003e\n  \u003cli\u003eComplete kit: flush valve, flapper, gasket, toilet wrench, bolts, washers, and nuts\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for high efficiency toilets (HET) with 3 inch flush valves\u003c\/li\u003e\n  \u003cli\u003ePackaged in a quantity of 5 units per package for service stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a universal OEM-style replacement for most common residential high efficiency toilets (HET) with a 3 inch flush valve configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified service technician. Shut off the water supply valve at the base of the toilet and flush to drain the tank before beginning disassembly. Follow all applicable local plumbing codes, including IPC guidelines, when servicing toilet flush valve assemblies. Do not overtighten the flush valve nut; hand-tight plus a firm quarter-turn with the included tool is standard practice to avoid cracking the tank.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlush Valve Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: High Efficiency Toilet (HET)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.85 pounds\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: FLUIDMASTER INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K-540A-015-T5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLUIDMASTER","offers":[{"title":"Default Title","offer_id":51525407539506,"sku":"K-540A-015-T5","price":94.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1b490021c4871e8e2e15a5571be0dad.jpg?v=1785472956","url":"https:\/\/voomisupply.com\/products\/fluidmaster-inc-k-540a-015-t5-3-inch-flush-valve-repair-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
