The ball attaches to a float arm via a 3\/8-inch threaded connection and rises or falls with the water level to open or close the supply valve automatically. At 8 inches in diameter, this is a full-size float suited for larger storage tanks, cisterns, cooling tower basins, and similar applications. Licensed plumbers and mechanical contractors install this type of component during new construction, system retrofits, and float valve replacements. The copper construction provides corrosion resistance in potable and non-potable water service.\u003c\/p\u003e\u003cp\u003eThis float ball is appropriate for residential and light commercial water storage and distribution applications where a float-operated fill valve controls tank water level. Typical installations include toilet flush tanks with compatible valve assemblies, atmospheric storage tanks, and open cooling system sumps. The 3\/8-inch threaded shank fits standard float arm connections found in many commonly used ball-cock and fill valve assemblies. Verify thread pitch and arm compatibility before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch diameter copper construction for positive buoyancy and durable service life\u003c\/li\u003e\n\u003cli\u003e3\/8-inch threaded connection for attachment to standard float arm assemblies\u003c\/li\u003e\n\u003cli\u003eCopper material resists corrosion in both potable and non-potable water systems\u003c\/li\u003e\n\u003cli\u003eFull-size float provides reliable water level sensing in larger tank applications\u003c\/li\u003e\n\u003cli\u003eLightweight at 1.6 pounds for easy handling and reduced arm stress\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement float ball for float-operated fill valve and ball-cock assemblies using a 3\/8-inch threaded float arm connection. Confirm thread size, arm length, and valve type before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber. Shut off the water supply and drain the tank before removing the existing float ball. Thread the 780333 onto the float arm by hand and tighten snugly without over-torquing the threaded connection on the copper ball. After installation, restore water supply and verify that the float shuts off flow at the correct water level, adjusting the float arm bend or adjustment screw as needed per the valve manufacturer instructions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 98268703115\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 780333\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51233966686514,"sku":"780333","price":441.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307614450.jpg?v=1780113426","url":"https:\/\/voomisupply.com\/products\/watts-780333-copper-float-ball-8-in-3-8-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
