This model ships without a Drain Line Flow Control (DLFC) button, which must be selected based on tank size: use 1.2 GPM for 8\"×44\" tanks, 1.5–2.0 GPM for 9\"×48\" systems, 2.4 GPM for 10\"×54\", 3.0 GPM for 12\"×52\", and 3.5–5.0 GPM for larger 13\"×54\" to 14\"×65\" vessels. The modular injector\/drain assembly allows for quick servicing without removing the valve from the tank. Annual power consumption is minimal thanks to the single-motor design that handles both timekeeping and valve actuation.

diameter mineral tanks, as well as iron filters, sediment filters, carbon filters, and neutralizing filters in 6\" to 10\" diameter tanks. This model requires a separately-purchased drain line flow control (DLFC) sized to match your tank diameter and desired backwash rate: 1.2 GPM for 8\" x 44\" tanks, 1.5 GPM for 9\" x 48\", 2.0 GPM for 9\" x 48\", 2.4 GPM for 10\" x 54\", 3.0 GPM for 12\" x 52\", 3.5 GPM for 13\" x 54\", 4.0 GPM for 13\" x 54\", and 5.0 GPM for 14\" x 65\" tanks. The #1 injector included with this valve is suitable for most residential softening applications; consult your system design specifications if a different injector size

The #1 injector configuration works with standard residential brine tanks and provides adequate draw for most softening resin beds. This is a down-flow regeneration valve only (not the up-flow model), so verify your system design requires down-flow before ordering. The valve does not include a drain line flow control (DLFC), which is acceptable for most municipal drain systems but may not meet code in certain jurisdictions requiring reduced drain flow rates.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"pro-tip\"\u003e\n 🔧 \u003cstrong\u003ePro tip:\u003c\/strong\u003e The 5600's injector and brine valve assembly can be removed and serviced from the exterior without disassembling the entire valve body.

The 3-cycle valve design works with a variety of residential filter tanks and media configurations. For metered softener applications, consider the 5-cycle metered versions of the 5800 platform.

designed for whole-house iron, manganese, and hydrogen sulfide removal without chemical injection. The valve maintains an air pocket at the top of the filter tank to oxidize dissolved contaminants on contact, then captures precipitated particles in the media bed—backwashing and recharging the air

tube. It pairs with oxidizing media including Birm, Filox-R, Pro-OX, and catalytic carbon—media choice depends on incoming iron concentration (up to 10 ppm), hydrogen sulfide levels, and pH. Catalytic carbon is recommended for hydrogen sulfide applications. The system requires a minimum 20 PSI inlet pressure, 120V power, and a drain line for backwash discharge. Tank size should be selected based on peak household flow demand and contaminant loading. Professional installation is recommended to ensure proper media depth, backwash flow rate, and timer programming.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"ro-section\"\u003e\n\u003cdiv class=\"ro-label\"\u003eIDEAL APPLICATIONS\u003c\/div\u003e\n\u003ch3 class=\"ro-title\"\u003eUse Cases and Water Conditions\u003c\/h3\u003e\n\u003cp\u003eThis valve is engineered for residential and light commercial well water systems with dissolved iron (up to 10 ppm), manganese, and hydrogen sulfide (rotten egg odor). Common applications include whole-house pre-filtration before water softeners or reverse osmosis systems, replacement heads for existing 2510-series tanks, and chemical-free iron filter upgrades. Suitable for homes with 1–3 bathrooms, rental properties, and light commercial installations where automated, maintenance-free oxidation filtration is required without the complexity of chemical feed

Compatible with Birm, Filox-R, Pro-OX, greensand, and catalytic carbon media — select media based on incoming iron, manganese, and sulfur levels. Recommended tank sizes range from 9\"×48\" to 12\"×52\" depending on household flow demand and contaminant concentration. The system requires minimum 20 PSI inlet pressure, a drain line for backwash discharge, and standard 120V AC power. This model does not include a day-of-week LCD display (DLFC); programming is based on 12-day timer clock intervals. Professional installation is recommended for proper media bed depth, backwash flow rate verification, and timer programming.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Fleck","offers":[{"title":"Default Title","offer_id":46437733007531,"sku":"FL2510AIO-SXT (NC)","price":1021.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0446\/7677\/6098\/files\/IMG_4182.webp?v=1775880461"}],"url":"https:\/\/www.isopurewater.com\/collections\/fleck-valves.oembed","provider":"Isopure Water","version":"1.0","type":"link"}
