It pairs a 20-inch Pentair Pentek Big Blue 5-micron sediment pre-filter, a Clack non-backwashing upflow whole-house carbon tank with 1.5 cubic feet of granular activated carbon in a Vortech 10 by 54 mineral tank, and the NSF\/ANSI 55 Class A certified Viqua VH410 ultraviolet sterilizer at a validated 40 mJ\/cm2 dose and 14 GPM whole-house service flow, in the order water must flow through them for the UV to actually inactivate 99.99% of bacteria. Free shipping to the lower 48, free pre-purchase phone consultation with Aidan at 800-460-5810 before you buy, and free remote sizing support after you buy. Ships pre-loaded with media installed in the carbon tank and the UV bulb pre-seated in the chamber.\u003c\/p\u003e\n\n\u003ch3\u003eBest for and not for\u003c\/h3\u003e\n\n\u003cp\u003eBest for: private well water households with documented coliform or E. coli contamination on a recent lab test, peak whole-house demand of 8 to 14 gallons per minute (typically 2 to 4 occupants and 2 to 3 bathrooms), incoming water already meeting UV-clean specs (sediment under 10 micron, iron under 0.3 ppm, manganese under 0.05 ppm, hardness under 7 grains per gallon, tannins controlled, UV transmittance above 75% at 254 nm), homes with shallow wells or spring-fed wells with intermittent contamination history, and households with immunocompromised members (infants, elderly, transplant recipients, chemotherapy patients) who need belt-and-suspenders disinfection on top of well-shock chlorination. Use this if your only well water problem is bacteria plus light taste and odor, and your test results otherwise look clean.\u003c\/p\u003e\n\n\u003cp\u003eNot for: wells with measurable iron above 0.3 ppm, manganese above 0.05 ppm, hardness above 7 grains per gallon, hydrogen sulfide rotten-egg smell, low pH below 6.0, tannins, or heavy sediment loads above 10 micron. Iron, manganese, hardness, and turbidity all cast UV shadows and let bacteria pass through alive, no matter how high the dose rating. If your water test shows any of those, step up to a system that adds an iron filter, acid neutralizer, or softener upstream of the UV stage. Call Aidan and we will route you to the correct package. Also not for chloraminated municipal water (chloramine already disinfects and the UV is redundant), households over 4 bathrooms or peak flow above 14 GPM (the VH410 dose drops below the validated 40 mJ\/cm2 above 14 GPM), or whole-home demand under 5 GPM (the VH200 single-stage UV is the cheaper correct answer).\u003c\/p\u003e\n\n\u003ch3\u003eWatch the install and review video first\u003c\/h3\u003e\n\n\u003cp\u003eWatch our walkthrough \"Best UV Light for Well Water: Viqua VH410 Review (32 Years Experience)\" on YouTube before buying: https:\/\/www.youtube.com\/watch?v=AcHv1usdKdM.

Sediment particles, iron flakes, dissolved organics, and tannins all create shadows where bacteria hide from the UV beam and survive the trip through the chamber. NSF\/ANSI 55 Class A certification is rated against UV-clean water. Drop a single 5-micron sediment particle into the chamber and the certified 40 mJ\/cm2 dose drops to whatever fraction of the bacteria actually saw the light. Every UV failure call we get is a UV unit installed without the right pre-filtration upstream. The 20-inch Pentek Big Blue 5-micron cartridge plus the 1.5 cubic foot upflow carbon tank in this package solve that problem before water reaches the Viqua chamber.\u003c\/p\u003e\n\n\u003ch3\u003eStage-by-stage breakdown\u003c\/h3\u003e\n\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage 1, 20 inch Big Blue sediment pre-filter:\u003c\/strong\u003e Pentair Pentek 150233 Big Blue housing with a 4.5 by 20 inch 5 micron polyspun polypropylene cartridge.

Sediment housing first, then the upflow carbon tank, then the UV chamber, in that order. The UV chamber must be the last stage before water enters the household plumbing so nothing recontaminates between disinfection and tap. 1 inch FNPT connections at every stage, standard household plumbing tools, copper or PEX both work. The UV stage requires one standard 110 to 120 volt grounded outlet within 6 feet, plus 36 to 100 degree Fahrenheit ambient temperature and 25 to 100 psi inlet pressure. No drain line and no electrical work needed for the sediment or carbon stages. Most homeowners self-install in 2 to 4 hours, or hire a local plumber for 1 to 2 hours of labor. Bypass valves are sold separately if not already on your plumbing. Ships pre-loaded with carbon media in the tank and the UV lamp pre-seated in the chamber so the only on-site media handling is dropping the polyspun cartridge into the Big Blue housing.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty and ongoing support\u003c\/h3\u003e\n\n\u003cp\u003eUV chamber 7 years, UV ballast 1 year, UV lamp 1 year, carbon tank 10 years structural, Clack C1190 carbon valve 5 years, Pentek Big Blue housing 1 year.

We stock replacement UV lamps, quartz sleeves, sediment cartridges, carbon media refills, and Clack valve parts and ship same to next business day from our warehouse, not back-ordered through a distributor.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this work if my well also has iron or hardness?\u003c\/strong\u003e No. UV light cannot penetrate iron-stained water or scale-clouded water effectively. If your test shows iron above 0.3 ppm, manganese above 0.05 ppm, or hardness above 7 grains per gallon, you need to add an iron filter and\/or softener upstream of the UV stage. Call Aidan at 800-460-5810 with your test results and we will recommend the correct package.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow often does the UV lamp need to be replaced?\u003c\/strong\u003e Annually, regardless of hours of use. UV lamp output drops below the validated 40 mJ\/cm2 dose rating at around 9000 hours of continuous on-time, and Viqua publishes the annual change interval on that basis. The VH410 alarm fires automatically when it is time. Replacement lamps are stocked and shipped from us.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to disinfect my well before installing this UV system?\u003c\/strong\u003e Yes. Shock chlorinate the well first to clear out the existing bacterial colony living in the well casing, plumbing, and water heater. Then install the UV system to keep the water bacteria-free going forward. UV does not retroactively clean a contaminated plumbing system, it only inactivates bacteria as water flows through the chamber.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat size household will this UV bundle support?\u003c\/strong\u003e 2 to 4 person households with up to 3 bathrooms and peak whole-house flow demand of 8 to 14 GPM. The 1.5 cubic foot upflow carbon tank is the bottleneck stage. Larger households (4 plus bathrooms or peak flow over 14 GPM) need to step up to a 2.5 cubic foot carbon tank and a larger Big Blue or twin-housing sediment configuration. Call us and we will size it correctly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does this compare to a single-stage Viqua UV system?\u003c\/strong\u003e A standalone Viqua VH410 is the UV stage only. Without sediment and carbon pre-filtration, the validated 40 mJ\/cm2 dose only holds against UV-clean water. Real well water arrives with sediment, dissolved organics, and trace chlorine that all degrade UV effectiveness. The 3-stage bundle is what makes the certified UV dose actually deliver 99.99% inactivation in real households.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the carbon stage required for bacterial disinfection?\u003c\/strong\u003e The carbon stage removes dissolved organics that absorb UV light at 254 nm and shadow bacteria from the beam. Without it, well water with even mild tannin or organic background reduces the effective UV dose below the 40 mJ\/cm2 certified threshold. The carbon also removes any chlorine taste residue from your shock-chlorination treatment. We do not sell a sediment-plus-UV-only configuration of this bundle for that reason.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the UV system run continuously or only when water flows?\u003c\/strong\u003e The Viqua VH410 lamp runs continuously, 24 hours a day, 365 days a year, even when no water is flowing. This is intentional. UV lamps degrade faster from on-off cycling than from continuous operation, and the chamber must be at full UV dose the instant water flow starts to disinfect that first gallon. Power consumption is 65 watts continuous, roughly $60 to $90 per year on average residential electricity rates.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat happens if the UV lamp fails?\u003c\/strong\u003e The VH410 has a continuous UV intensity sensor that monitors actual dose in real time, plus a low water cutoff and an audio and visual alarm on lamp failure or quartz sleeve fouling. The alarm fires before any disinfection-failure event reaches your tap. Replacement lamp installation is a 5-minute job: power off, twist off the end cap, swap the lamp, twist back on, power on. We ship replacement lamps next business day.\u003c\/p\u003e\n","brand":"Mid Atlantic Water","offers":[{"title":"Default Title","offer_id":54082573107484,"sku":null,"price":2195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/9523\/4605\/files\/well-water-uv-sanitizer-system_c76aee8c-9714-4bec-a024-08e76ec6fc7d.jpg?v=1778182109","url":"https:\/\/midatlanticwater.net\/products\/well-water-uv-sanitizer-system","provider":"Mid Atlantic Water","version":"1.0","type":"link"}
