Stains laundry, fixtures, toilet bowls, dishwashers, and ice. Tastes earthy, swampy, or astringent. Tannins commonly appear together with hardness because the same shallow or surface-influenced wells that pick up organic color also tend to be high in calcium and magnesium. This bundle treats both problems in a single low-maintenance train.\u003c\/p\u003e\n\n\u003cp\u003eTalk to Aidan before you buy. Free expert consultation at 800-460-5810, 7 days a week, 8 AM to 5 PM Eastern. Send your well water test results and Aidan will confirm tannins are the actual cause of your color problem (iron above 0.3 ppm causes nearly identical staining and needs a completely different system) and recommend the right configuration for your household size, plumbing, and well chemistry. No upsell, no commission, no hard sell.

Sediment filters do not remove them because tannins are dissolved, not particulate. Standard activated carbon adsorbs some tannins but is rapidly overwhelmed by the high organic loading typical of tannin wells. Reverse osmosis blocks tannins but only at the point of use, not whole-house, and tannins quickly foul RO membranes. Oxidation systems (chlorine, ozone, hydrogen peroxide) can break tannin color but require dosing pumps, contact tanks, and careful pH control. The clean answer for whole-house tannin removal is anion exchange: a resin engineered to swap chloride ions for tannin molecules and regenerate with salt brine. This system uses that resin in stage 2.\u003c\/p\u003e\n\n\u003ch3\u003eCommon contaminants and conditions treated\u003c\/h3\u003e\n\n\u003cp\u003eTannins (organic color, fulvic acid, humic acid), yellow water, brown water, tea-colored water, swamp-tasting water, earthy taste, musty taste, calcium hardness, magnesium hardness, scale, soap scum, hard water spots, sediment, sand, silt, rust flakes, chlorine, chloramine, VOCs (volatile organic compounds), pesticide residues, and general taste and odor problems.

Standard plumbing sequence is: well pump and pressure tank, then sediment pre-filter, then tannin filter, then softener, then carbon polish, then to the house. Each tank is plumbed in series with a bypass valve so any single stage can be isolated for service without shutting off house water. Requires a nearby drain (floor drain, utility sink, sump, or laundry standpipe) for stages 2 and 3 regeneration discharge, and two standard 110-120V outlets for the Fleck control valves. Ships pre-loaded with media; you do not need to load resin or carbon yourself. Most homeowners hire a local plumber for the install (typical 4 to 6 hours) or self-install with basic plumbing experience.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty and ongoing support\u003c\/h3\u003e\n\n\u003cp\u003e5-year warranty on the Fleck control valves, 5-year warranty on the Clack WS1, 10-year structural warranty on all media tanks. Lifetime phone support from Aidan at 800-460-5810 for sizing questions, install troubleshooting, programming the Fleck valve, water test interpretation, and media replacement timing. Support is remote because Mid Atlantic Water is online-only and ships nationally; we do not install in any geography but we walk customers through every step of the install over the phone.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked questions for this system\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I know if I have tannins or iron?\u003c\/strong\u003e Both cause yellow to brown water but the chemistry is completely different. Tannins are organic and dissolved; iron is inorganic and forms reddish particles when oxidized. A standard well water test that measures both iron (in ppm) and tannins (typically reported as color in apparent color units or as a pass\/fail on the tannin test) tells you which one. If the test shows iron above 0.3 ppm, you need an iron filter system, not this one. Call Aidan at 800-460-5810 with your test results and he will confirm the right system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this system make my water safe to drink?\u003c\/strong\u003e This system removes tannins, hardness, sediment, chlorine, and general taste and odor problems. It does not disinfect (use UV for bacteria), it does not remove arsenic, nitrate, lead, or PFAS, and it does not correct low pH. If your water test shows any of those, you need additional treatment. The phone consultation will walk through your full water test to identify any gaps.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much salt does this system use?\u003c\/strong\u003e Both the tannin filter (stage 2) and the softener (stage 3) regenerate with brine. Combined salt use depends on water chemistry, household water use, and programmed regeneration frequency. Typical range is 60 to 120 pounds of solar salt or pellet salt per month for a household of 4 with moderate tannin and hardness loading. Each tank has its own brine tank so salt is added independently.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e Yes, with basic plumbing skills. Most customers hire a local plumber for a 4 to 6 hour install. The system ships pre-loaded with media, includes all bypass valves and unions, and Aidan provides direct phone support during install. We do not install in any geography because Mid Atlantic Water is an online-only national ecommerce business; the support is remote.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between this system and a regular water softener with tannin resin blended in?\u003c\/strong\u003e Some softeners offer a tannin and hardness combination resin in a single tank. That works for low tannin levels (under 1 ppm) and low hardness. For tannin levels above 1 ppm or hardness above 15 grains per gallon, a dedicated tannin filter ahead of the softener removes more tannins, lasts longer between regenerations, and protects the softening resin from organic fouling. This system uses dedicated stages for that reason.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo you ship to my state?\u003c\/strong\u003e Yes. Mid Atlantic Water ships to all 50 US states with free standard shipping on this system.
