This precision injector uses a venturi throat to turn service-water flow into the suction that lifts salt brine from the tank and carries it through the resin during regeneration. It is part of the Fleck Injector service family and is matched to the 5812 valve platform.\u003c\/p\u003e\u003cp\u003eThe #3 injector is sized for larger tank diameters and higher flow than the lower-numbered options, making it the right pick when your system specifications call for it. The principle is the same across all sizes: water accelerating through the narrow throat drops in pressure and creates a vacuum on the brine line, drawing concentrated salt solution into the media where sodium ions exchange with hardness ions. Correct injector sizing is what guarantees the resin receives a full, properly concentrated brine charge for a complete regeneration.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine Fleck #3 injector for 7000 and 5810\/5812 valves\u003c\/li\u003e\n\u003cli\u003eVenturi-based design for dependable brine suction\u003c\/li\u003e\n\u003cli\u003eSized for larger-diameter softener tanks\u003c\/li\u003e\n\u003cli\u003eReplaces clogged or eroded injectors\u003c\/li\u003e\n\u003cli\u003eBrings regeneration and softening back to spec\u003c\/li\u003e\n\u003cli\u003ePrecision component for consistent performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eMaintenance Tip\u003c\/h3\u003e\u003cp\u003eAn injector throat the diameter of a pinhole is easily blocked by sediment, iron, or salt fines, and a blocked injector is the classic reason a softener cycles without actually softening. When that happens, the brine tank stops drawing down and hard water gradually returns, even though the valve appears to step through its stages normally. Keep a spare on hand so you can restore service quickly, and inspect the injector screen whenever you service the valve to catch debris before it reaches the throat. Match the #3 size to your tank and flow before installing, clean the screen at the same time so the fresh injector stays clear, and depressurize the valve before removing the injector cap. With the right injector installed, your system will pull a full brine charge every cycle. Because the injector is inexpensive relative to the value of reliable soft water, keeping the correct size on hand for your larger system makes routine maintenance and troubleshooting fast and stress-free.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668811767861,"sku":"FL61454-3","price":45.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/fl61454-3.jpg?v=1782534185","url":"https:\/\/watersoftenerplus.com\/pl-eu\/products\/fleck-injector-3-7000-5810-12-valve","provider":"Water Softener Plus","version":"1.0","type":"link"}
