{"product_id":"fleck-blfc-assy-1-0-gpm-1-2","title":"Fleck BLFC Assy, 1.0 GPM 1\/2\"","description":"\u003cp\u003eThis genuine Pentair Fleck BLFC Assembly delivers a controlled 1.0 GPM refill rate through a 1\/2\" brine line on Fleck 5812 control valves. As a brine line flow control, it sets the exact rate at which water enters the brine tank, ensuring the right volume is added to dissolve salt and prepare brine for the next regeneration. It belongs to the Fleck BLFC service family and is built to match the 5812 valve platform.\u003c\/p\u003e\u003cp\u003eThe defining feature of this version is its larger 1\/2\" brine line connection, making it the correct choice for systems plumbed with 1\/2\" tubing rather than the narrower 3\/8\" size. Matching the BLFC to your actual brine line diameter is important both for a proper physical fit and for accurate flow, so be sure to verify your line size before ordering. The calibrated orifice holds the 1.0 GPM rate steady even as household water pressure rises and falls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine Fleck 5812 brine line flow control\u003c\/li\u003e\n\u003cli\u003e1.0 GPM rate for 1\/2\" brine line connections\u003c\/li\u003e\n\u003cli\u003eMeters brine-tank refill for proper salt dosing\u003c\/li\u003e\n\u003cli\u003eMaintains consistent flow across pressure changes\u003c\/li\u003e\n\u003cli\u003ePromotes salt efficiency and reliable softening\u003c\/li\u003e\n\u003cli\u003eDirect replacement for a clogged or worn BLFC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKeeping Brine Dosing Accurate\u003c\/h3\u003e\u003cp\u003eBecause the volume of water added to the brine tank determines how much salt dissolves, the BLFC effectively controls the salt dose for each regeneration. Hard or sediment-laden water can leave mineral deposits inside the flow control over time, throwing off the refill volume and causing salty water or a slow return of hardness. Replacing the BLFC restores precise metering and brings the softener back to spec. Confirm that the 1.0 GPM rating and 1\/2\" size match your existing brine plumbing, clear any debris from the fitting during service, depressurize the brine circuit before opening it, and check that the tank fills to the expected level once the new control is in place. Because the part is inexpensive and central to salt efficiency, replacing a suspect or heavily scaled BLFC outright is often the smarter choice, restoring accurate dosing and predictable operating costs in one quick step. Matching the flow control to your brine line and tank size keeps the salt cycle predictable, ensuring consistent soft water and steady operating costs throughout the year.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668811505717,"sku":"FL61451-100","price":46.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/fl61451-100.jpg?v=1782534170","url":"https:\/\/watersoftenerplus.com\/id-as\/products\/fleck-blfc-assy-1-0-gpm-1-2","provider":"Water Softener Plus","version":"1.0","type":"link"}
