Removes sand, silt, rust flakes, and particulate matter from incoming well water before it reaches the iron and sulfur filter, protecting the Katalox-Light media bed and the downstream UV chamber. 1 inch FNPT ports. Cartridge replaces every 6 to 12 months depending on sediment load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage 2: Fleck 2510AIO 2.5 Cubic Foot Air-Injection Iron and Sulfur Filter (13x54 tank, Katalox-Light media).\u003c\/strong\u003e 2.5 cubic feet of Katalox-Light catalytic filtration media pre-loaded into a 13 inch diameter by 54 inch tall tank with the Fleck 2510AIO control valve. The 2510AIO draws ambient air into the top of the tank during regeneration, creating an air pocket that oxidizes hydrogen sulfide gas and dissolved iron the instant water passes through it. Katalox-Light then traps the oxidized particles and the valve backwashes automatically at programmed intervals to flush them to drain. No chemicals, no chlorine injection, no peroxide, no cartridges, no daily maintenance. Removes hydrogen sulfide up to 5 ppm, iron up to 10 ppm (ferrous and ferric), and manganese up to 5 ppm. Operating pH range 5.6 to 10. Standard 110-120V outlet.

Polishes any residual hydrogen sulfide, taste, odor, chlorine, chloramine, and volatile organic compounds (VOCs) downstream of the iron and sulfur stage. Centaur outperforms standard activated carbon on chloramine and trace H2S reduction and protects the downstream UV lamp from organic film buildup that would shorten lamp life. No electricity, no drain, no backwash, no salt. Service flow up to 8 GPM continuous.

Sediment goes first so the 5 micron cartridge protects the Katalox-Light bed and the UV chamber from particulate fouling; the iron and sulfur filter goes before carbon so oxidized H2S and iron particles are filtered out before the carbon polish; carbon goes before UV so any organic film stays off the quartz sleeve; UV is the final step so disinfected water enters the home directly. Every stage uses 1 inch connections and is intended to install inline.\u003c\/p\u003e\n\n\u003ch3\u003eBest For This System\u003c\/h3\u003e\n\n\u003cp\u003eThis is the right whole-house package for a private well home in any U.S. state showing hydrogen sulfide \/ rotten egg smell on a recent water test (sulfide between 0.1 and 5 ppm), iron between 1 and 10 ppm (ferrous, ferric, or both), manganese between 0.1 and 5 ppm, pH between 5.6 and 10, total hardness below 25 grains per gallon, and a microbiologically suspect source (positive coliform, surface-influenced well, shallow well, well that has tested positive after a rain event, or any well that has not been chlorinated and re-tested in the past year), with 3 to 6 occupants and 2 to 4 bathrooms. Symptoms this system fixes: rotten egg smell from the hot water, rotten egg smell from the cold water, orange and red iron staining of laundry and fixtures, black manganese staining, metallic taste, sulfur taste, sulfur smell that gets worse after sitting overnight, the smell only at one faucet (often a hot-water-only sulfide problem), bacterial contamination on a positive coliform test, and the need for whole-house disinfection on a shallow or surface-influenced well.\u003c\/p\u003e\n\n\u003ch3\u003eNot For\u003c\/h3\u003e\n\n\u003cp\u003eThis bundle is not the right fit for any of the following: hydrogen sulfide above 5 ppm (step up to a peroxide injection or chlorine injection system), iron above 10 ppm (step up to a 3.5 cubic foot 2510AIO or add a chemical injection stage ahead of this train), low pH below 5.5 (add an acid neutralizer Stage 0 ahead of the iron and sulfur filter to raise pH first, otherwise Katalox-Light efficiency drops), hard water above 25 grains per gallon (add a salt-based water softener after the carbon stage), municipal city water on chlorine or chloramine without sulfide (a whole-house catalytic carbon filter is sufficient, no AIO or UV needed), or homes with 5+ bathrooms or 7+ occupants (step up to the 3.5 cubic foot iron and sulfur filter and a higher-flow UV). If your test shows any of those conditions, call 800-460-5810 before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eWatch the Walkthrough Video Before You Buy\u003c\/h3\u003e\n\n\u003cp\u003eWatch the 9-minute video \"Complete Guide to WHOLE HOUSE WATER FILTERS\" on YouTube before ordering: https:\/\/www.youtube.com\/watch?v=KJ3cqjamayA. It explains what a whole-house water filter actually is (a category, not a single product), shows the exact equipment Mid Atlantic Water installs, and walks through which combinations of stages you need based on what your water test shows. The video covers sediment filters, iron and sulfur filters, carbon filters, UV disinfection, and acid neutralizers, and is the fastest way to confirm this 4-stage Sulfur package is the right fit for your specific well water profile before you commit to it.\u003c\/p\u003e\n\n\u003ch3\u003eTalk to Aidan Before You Order: 800-460-5810\u003c\/h3\u003e\n\n\u003cp\u003eFree expert phone consultation before purchase.

Send your water test results (or order a kit from us first) and Aidan will confirm whether this 4-stage Sulfur system is sized correctly for your well, your sulfide concentration, your iron level, your bathroom count, and your occupants, or whether you should be looking at a different package (sometimes a single iron and sulfur filter is all you need, sometimes you need to step up to peroxide injection). No upsell, no commission, no hard sell. Mid Atlantic Water is an online-only national ecommerce business shipping to all 50 states; we do not install in any geography. Consultation, sizing, and ongoing support are remote (phone, text, email). Aidan has been doing residential well water sizing for years and can read a Tap Score, National Testing Labs, or local lab water test in under five minutes.\u003c\/p\u003e\n\n\u003ch3\u003eWhy a 4-Stage Bundle Instead of Buying Components Separately\u003c\/h3\u003e\n\n\u003cp\u003eOrdering this Sulfur package as a bundle saves money compared to buying the same four components individually at full price. The components are also matched and sized to work together: the Big Blue sediment filter is a 20 inch 5 micron model selected to feed the AIO and UV cleanly without overshooting their flow rate; the Fleck 2510AIO 2.5 cubic foot iron and sulfur filter is sized for 3 to 6 occupants and up to 4 bathrooms with sulfide up to 5 ppm and iron up to 10 ppm; the Clack 2.5 cubic foot Centaur catalytic carbon filter is sized to keep up with the AIO service flow and protect the UV; and the Viqua VH410 is the 18 GPM UV that matches the bundle flow rate at NSF Class A equivalent dose. Buying a la carte means picking four things from four product pages and hoping they line up. Buying the bundle means a sized, ordered, pre-loaded train ships in one delivery, ready to install.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eBundle level:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eSystem Configuration: 4-stage whole house treatment train (sediment plus air-injection iron and sulfur filter plus non-backwashing catalytic carbon plus Viqua VH410 UV)\u003cbr\u003e\nBundle Total Service Flow: 18 GPM continuous (limited by the Viqua VH410 UV at NSF Class A equivalent dose)\u003cbr\u003e\nInstallation Order: Stage 1 sediment, Stage 2 iron and sulfur filter, Stage 3 carbon, Stage 4 UV (after pressure tank, before home cold lines and water heater)\u003cbr\u003e\nConnection Size: 1 inch throughout (1 inch FNPT on the Big Blue, 1 inch on the AIO and carbon bypass valves, 1 inch MNPT on the UV chamber)\u003cbr\u003e\nPower Required: standard 110-120V grounded outlets for the Fleck 2510AIO valve and the Viqua VH410 UV controller (Stages 1 and 3 require no power)\u003cbr\u003e\nDrain Required: the Fleck 2510AIO regenerates to drain (washing machine standpipe or floor drain within 20 feet);

Plumbing position from incoming well line: pressure tank, Stage 1 (sediment), Stage 2 (iron and sulfur filter), Stage 3 (carbon), Stage 4 (UV), then home cold lines and water heater. The AIO and carbon both use 1 inch bypass valves, and the UV uses 1 inch MNPT, so a competent DIY plumber or a local plumber can connect the train with standard 1 inch CPVC, PEX, or copper. Required at the install location: two standard 110-120V outlets within 6 feet of the install (one for the Fleck 2510AIO valve, one for the Viqua VH410 UV controller), a drain (washing machine standpipe, floor drain, or condensate drain) within 20 feet of the AIO for backwash discharge, and roughly 5 feet of vertical clearance plus 2 feet of side clearance for media tank service.

It includes a 20 inch Big Blue 5 micron sediment pre-filter, a Fleck 2510AIO 2.5 cubic foot air-injection iron and sulfur filter on Katalox-Light media in a 13x54 tank, a Clack 2.5 cubic foot non-backwashing whole-house carbon filter on Centaur catalytic carbon in a 13x54 Vortech tank, and a Viqua VH410 ultraviolet sterilizer rated for 18 GPM at NSF Class A equivalent UV dose.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this system get rid of the rotten egg smell in my well water?\u003c\/strong\u003e Yes, for hydrogen sulfide concentrations up to 5 ppm. The Fleck 2510AIO uses air-injection oxidation to convert dissolved H2S gas into a solid particle that the Katalox-Light media traps and the valve backwashes to drain. The downstream Centaur catalytic carbon filter polishes any trace H2S that the AIO did not catch. For sulfide above 5 ppm, step up to peroxide injection or chlorine injection (call 800-460-5810).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this remove iron?\u003c\/strong\u003e Yes, up to 10 ppm of ferrous and ferric iron combined. The Fleck 2510AIO is the same air-injection iron filter we sell as a standalone iron and sulfur filter; this bundle adds the carbon and UV stages.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this kill bacteria?\u003c\/strong\u003e Yes. The Viqua VH410 UV stage delivers 99.99 percent (4-log) inactivation of E. coli, total coliform bacteria, Cryptosporidium, Giardia, viruses, rotavirus, and hepatitis A at 18 gallons per minute continuous flow. UV is the right fix for any well that has tested positive for coliform, any shallow or surface-influenced well, and any well that has not been chlorinated and re-tested in the past year.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this work on city water?\u003c\/strong\u003e Not the right fit. City water on chlorine or chloramine usually does not have hydrogen sulfide or iron, and it is already disinfected, so the AIO and UV stages are unnecessary. A standalone whole-house catalytic carbon filter is the right city water fix. Call 800-460-5810 for the right city configuration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this remove hardness or soften water?\u003c\/strong\u003e No. This bundle does not include a water softener. If your water test shows total hardness above 7 to 10 grains per gallon and you want to eliminate scale on water heater elements, faucet aerators, and glassware, add a salt-based water softener after the carbon stage. Call 800-460-5810 for a softener-added configuration quote.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this raise pH if my well water is acidic?\u003c\/strong\u003e No. This bundle does not include an acid neutralizer. The Fleck 2510AIO operates correctly between pH 5.6 and 10. If your raw pH is below 5.6, add an acid neutralizer Stage 0 ahead of this train. Call 800-460-5810 if you have low pH on top of sulfide and iron.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow often does the Fleck 2510AIO regenerate?\u003c\/strong\u003e The 2510AIO time-clock regenerates on a programmed schedule, typically once every 2 to 4 days at the factory default for a 3-to-6-person household with the listed contaminant load. Regeneration takes about 90 minutes and runs in the early morning. The valve draws ambient air to refresh the air pocket and backwashes accumulated solids to drain.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow long does the Katalox-Light media last?\u003c\/strong\u003e 8 to 10 years before replacement on typical residential well water. Centaur catalytic carbon in the Stage 3 carbon filter lasts 7 to 10 years on similar duty. Routine annual touchpoints are the UV lamp swap (annual) and the sediment cartridge swap (every 6 to 12 months).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan a homeowner install this themselves?\u003c\/strong\u003e Yes, if comfortable with sweating copper, gluing CPVC, or crimping PEX, and a basic understanding of bypass valves and drain plumbing. Otherwise hire a local plumber. Mid Atlantic Water provides free phone support during the install at 800-460-5810; we do not send installers (we are an online-only national ecommerce business shipping to all 50 states).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow long does the system take to ship?\u003c\/strong\u003e Free shipping in the contiguous United States, typically 5 to 10 business days door to door.
