{"product_id":"large-home-well-water-system","title":"6-Stage High-Flow Whole House Well Water Filter System (5+ Bath)","description":"\u003cp\u003eWhole-house well water system for large homes with 5+ bathrooms, 6-stage train using oversized 3.5 cubic foot iron and acid-neutralizer tanks plus an 80,000-grain softener, sized for 5 to 8 person households with 5 to 7 bathrooms.\u003c\/p\u003e\n\n\u003cp\u003eThis is the high-flow build of MAW's Ultimate Well Water System, configured for households where multiple showers, a dishwasher, washing machine, and outdoor fixtures run simultaneously. Standard 2.5 cubic foot treatment tanks bottleneck at peak demand in a 5-bathroom home; this system steps up to 3.5 cubic foot tanks on the iron filter and acid neutralizer, plus an 80,000-grain softener (versus the standard 64,000-grain), so the home delivers 14 to 17 GPM continuously across all six treatment stages without pressure drop, iron breakthrough, or mid-cycle softener exhaustion.\u003c\/p\u003e\n\n\u003cp\u003eBest for: private well households with 5 or more bathrooms, 5 to 8 occupants, simultaneous peak demand from 4+ fixtures, and a comprehensive water test showing iron, low pH, hardness, chlorine or VOC concerns, and any bacterial or coliform risk. Step down to the Ultimate Well Water System (2.5 cubic foot tanks, 64,000-grain softener, $1,200 less) for 3 to 4 bathroom homes with 3 to 5 occupants. Step down further to the Small Home Well Water System for 1 to 3 bathroom homes. Not suitable for municipal city water (use the city water bundle), homes without an existing pressure tank, or installations where the well pump cannot deliver at least 8 GPM at 50 PSI to the treatment train inlet.\u003c\/p\u003e\n\n\u003cp\u003eWatch first: \"Iron Filters for Well Water: The Complete Guide\" on YouTube covers how the iron filter stage works, the four common installation mistakes, and how to interpret your water test results. Pair with \"Water Softeners: The Complete Guide\" and \"Acid Neutralizers: The Complete Guide\" for the rest of the train.\u003c\/p\u003e\n\n\u003cp\u003eFree expert consultation before you buy.

No chemicals, no chlorine injection, no daily salt addition. Self-cleans on a scheduled backwash cycle.\u003c\/li\u003e\n\u003cli\u003eStage 3, acid neutralizer (3.5 cubic feet of calcite media): raises low pH from 5.5 to 6.9 up to a neutral 7.0 to 7.4 range, stopping copper pipe pinhole leaks, blue-green sink and tub staining, and pinhole corrosion of fixtures. Calcite is self-regulating and adds no electricity, no drain line at this stage, and no salt.\u003c\/li\u003e\n\u003cli\u003eStage 4, water softener (80,000 grain capacity, 10% crosslink resin, Fleck 5600SXT demand-initiated valve): removes hardness minerals (calcium and magnesium) so soap lathers, scale stops accumulating in water heaters and fixtures, and skin and hair feel cleaner. The 80,000-grain capacity gives a large household longer service runs between regenerations than the standard 64,000-grain build, which matters in 5+ bath homes.\u003c\/li\u003e\n\u003cli\u003eStage 5, whole-house carbon filter (Centaur catalytic carbon, non-backwashing Clack tank): polishes taste and odor, removes residual chlorine, chloramine, hydrogen sulfide pass-through, and a broad spectrum of volatile organic compounds (VOCs). No drain, no electricity, no annual cartridge replacement.\u003c\/li\u003e\n\u003cli\u003eStage 6, Viqua VH410 UV sterilizer: kills 99.99% of bacteria, viruses, cryptosporidium, and giardia at the final treatment step. NSF\/ANSI 55 Class B compliant validated dose at 14 GPM whole-house flow. Annual lamp replacement is the only ongoing consumable.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eWhy oversized for large homes\u003c\/h3\u003e\n\n\u003col\u003e\n\u003cli\u003ePeak-flow capacity. 3.5 cubic foot tanks hold ~30% more media than 2.5 cubic foot tanks, raising the maximum service flow before iron or hardness breakthrough from 12 GPM to 17 GPM.\u003c\/li\u003e\n\u003cli\u003eLonger regeneration intervals. The 80,000-grain softener treats roughly 25% more gallons between regenerations than a 64K, so a 6-person household running multiple loads of laundry and 5+ bathrooms does not exhaust capacity mid-week.\u003c\/li\u003e\n\u003cli\u003eLower pressure drop at peak. Oversized tanks operate at a lower face velocity through the media bed, so simultaneous showers and dishwasher cycles do not produce noticeable pressure drop downstairs.\u003c\/li\u003e\n\u003cli\u003eNo chemicals, no annual servicing on the iron and AN stages. Air injection is mechanical; calcite is consumable but lasts 4 to 6 years in typical low-pH wells before media top-off.\u003c\/li\u003e\n\u003cli\u003eFree pre-purchase phone consultation with Aidan at 800-460-5810.

Iron, AN, softener, and carbon tanks arrive with media already inside. Plug-and-plumb install via 1-inch female threaded bypass valves; standard 110-120V outlet for the softener and UV stages.

Step down to the Ultimate (2.5 cubic foot, 64K softener) if the home has 3 to 4 bathrooms and 3 to 5 occupants. Step down to the Small Home system for 1 to 3 bathroom households. Step up to a custom build if iron exceeds 30 ppm, hydrogen sulfide exceeds 10 ppm, the well pump delivers less than 8 GPM, or the household has 9+ occupants. Call 800-460-5810 to confirm before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation overview\u003c\/h3\u003e\n\n\u003cp\u003eInstall at the main water line entry point after the pressure tank, in the order shipped: sediment, iron and sulfur AIO, acid neutralizer, softener, carbon, UV. Each tank uses a 1-inch female threaded bypass valve so a competent DIYer can plumb the entire train with PEX, copper, or CPVC and standard threaded fittings in 4 to 6 hours. The iron filter, softener, and UV stage need a standard 110-120V grounded outlet. The iron filter and softener need a drain line for backwash and regeneration; the AN, carbon, and UV stages do not. Tanks ship pre-loaded with media. The Viqua UV controller wall-mounts; the lamp needs annual replacement. We ship free on a freight pallet to the lower 48 states; HI\/AK\/PR are quoted separately. Most homeowners can install this themselves in a Saturday; any local plumber can do the job in 6 to 8 hours.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty and ongoing support\u003c\/h3\u003e\n\n\u003cp\u003e5-year warranty on all Fleck control valves, 10-year structural warranty on all media tanks, 5-year warranty on the Viqua UV chamber. Lifetime phone, text, and email support from Aidan at 800-460-5810 (Mid Atlantic Water customer support, Mon-Sun 8 AM to 5 PM Eastern, USA-based, no offshore call center). If a part fails, we ship the replacement direct from the manufacturer and walk you through the swap on the phone. If you ever sell the house, the warranty transfers to the new owner.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked sizing and configuration questions\u003c\/h3\u003e\n\n\u003cp\u003eDo I need the 3.5 cubic foot oversized version, or will the 2.5 cubic foot Ultimate work? If your home has 5 or more bathrooms, 6+ occupants, or simultaneous high-flow demand from 4+ fixtures, choose the 3.5 cubic foot oversized configuration. Otherwise the 2.5 cubic foot Ultimate is the right fit and saves $1,200.\u003c\/p\u003e\n\n\u003cp\u003eWill this system handle iron at 25 ppm and pH at 5.8 simultaneously? Yes. The iron filter handles up to 30 ppm and the acid neutralizer handles 5.5 to 6.9 pH. Both stages are sized to operate together at full flow.\u003c\/p\u003e\n\n\u003cp\u003eDo I need a plumber? No, but you can use one. Most large-home customers either DIY in a Saturday or hire a local plumber for 6 to 8 hours of labor. Tanks ship pre-loaded.\u003c\/p\u003e\n\n\u003cp\u003eHow much does it cost to run? The softener uses ~40 lb of salt every 4 to 8 weeks ($8 to $15) for a 6-person household. The UV lamp is ~$120 once a year. The iron and AN stages have no monthly consumables. Total annual operating cost is typically $200 to $350.\u003c\/p\u003e\n\n\u003cp\u003eWhat if my well pump cannot deliver 8 GPM at 50 PSI? Call before ordering. We may recommend a constant-pressure pump upgrade or a smaller treatment configuration that fits your pump capacity.\u003c\/p\u003e\n\n\u003cp\u003eHow long does media last? Iron and carbon media: 8 to 10 years. Softener resin: 10 to 15 years. Calcite (acid neutralizer): 4 to 6 years before top-off, fully replenishable for ~$120 of calcite without replacing the tank. UV lamp: 1 year (annual replacement, ~$120).\u003c\/p\u003e\n\n\u003cp\u003eDo you ship to my state? Yes, all 50 states. Free freight pallet to the lower 48; HI, AK, and PR are quoted separately at order time. Mid Atlantic Water is an online-only national ecommerce business; we do not install in any state but we provide phone consultation, sizing, and ongoing support remotely for all 50 states.\u003c\/p\u003e\n\n\u003cp\u003eCan I add a reverse osmosis drinking water system? Yes. Most large-home customers add an under-sink RO at the kitchen for the drinking and cooking tap. Call 800-460-5810 to bundle.\u003c\/p\u003e\n","brand":"Mid Atlantic Water","offers":[{"title":"Default Title","offer_id":54082573566236,"sku":null,"price":9495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/9523\/4605\/files\/large-home-well-water-system_08c3f87d-0d10-4d28-9dda-f89179dd70e9.jpg?v=1778182100","url":"https:\/\/midatlanticwater.net\/products\/large-home-well-water-system","provider":"Mid Atlantic Water","version":"1.0","type":"link"}
