Nozzle #6wht","description":"\u003cp\u003eThe FL15128-06 is a Fleck 1800 Brine Valve Injector Nozzle in size #6 White, a genuine Pentair metering part for Fleck control valves including the 3900. As the jet element of the valve's venturi injector, this nozzle accelerates service water to create the suction that draws brine from the salt tank into the resin during regeneration. The white #6 sits among the larger sizes in the Fleck injector lineup, delivering a higher draw rate than the smaller-numbered nozzles.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine Fleck 1800 brine-valve injector nozzle\u003c\/li\u003e\n\u003cli\u003eSize #6, white color code for its flow rating\u003c\/li\u003e\n\u003cli\u003eLarger draw rate than smaller-numbered nozzles\u003c\/li\u003e\n\u003cli\u003eCompatible with Fleck 3900 control valves\u003c\/li\u003e\n\u003cli\u003eLightweight precision component, roughly 0.01 lb\u003c\/li\u003e\n\u003cli\u003eBest paired with the matching #6 throat\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFleck color-codes its injectors so each tank diameter gets the proper brine-draw rate, and the white #6 is typically suited to bigger resin beds that need more brine flow to regenerate fully. For correct operation it should be matched with the corresponding #6 throat so the venturi passage stays dimensionally accurate. Mixing mismatched sizes or colors changes the suction characteristics and can leave the resin only partly recharged or waste salt.\u003c\/p\u003e\u003cp\u003eBecause the nozzle's small orifice can collect iron, sediment, or salt buildup over time, brine draw can weaken gradually until softening performance noticeably declines. On larger systems, this often shows up as a slow return of hardness even though the valve appears to be cycling on schedule. The tiny passage is easy to overlook as a fault source, yet it has an outsized effect on how completely the resin regenerates.\u003c\/p\u003e\u003cp\u003eIf a larger Fleck softener has lost capacity or is leaking hardness, a clogged or worn injector nozzle is a common and inexpensive culprit. Installing this genuine #6 white nozzle, paired with a clean throat, restores full venturi suction and dependable regeneration on 3900-equipped systems, keeping the home's water consistently soft.\u003c\/p\u003e\u003cp\u003eFor technicians, carrying the larger white #6 nozzle alongside the smaller sizes ensures the truck is ready for the full range of tank diameters they may encounter. Because the #6 serves bigger resin beds that demand more brine flow, getting this size right is especially important to fully recharging a large system. Treating the nozzle and matching throat as a paired wear item gives the most reliable result and keeps a high-capacity Fleck softener performing at its rated output.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668803608629,"sku":"FL15128-06","price":51.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/fl15128-06.jpg?v=1782533821","url":"https:\/\/watersoftenerplus.com\/es-eu\/products\/fleck-1800-bv-inj-nozzle-6wht","provider":"Water Softener Plus","version":"1.0","type":"link"}
