Check Before You Buy\u003c\/h3\u003e\n\u003cp\u003eYellow water has two common causes, and they need different equipment. Fill a clear glass and let it sit overnight: if the color settles to the bottom, it is likely iron or sediment; if the water stays uniformly tinted, it is dissolved organics (tannins). Labs report the parameter as \"Tannin-Lignin.\" If your test shows meaningful iron alongside low tannins, treat the iron first - read our guide to the \u003ca href=\"\/blogs\/faqs\/types-of-iron-in-well-water\"\u003etypes of iron in well water\u003c\/a\u003e, or confirm with a \u003ca href=\"\/products\/tannins-water-test-kit\"\u003ecertified lab tannin test\u003c\/a\u003e before spending on equipment.\u003c\/p\u003e\n\n\u003ch3\u003eRuns Like a Water Softener\u003c\/h3\u003e\n\u003cp\u003eThe 5600SXT meters your water use and regenerates the resin with a sodium chloride brine, exactly like a water softener. Your only routine job is keeping \u003cstrong\u003ewater softener salt\u003c\/strong\u003e in the brine tank. One tannin-specific rule: regenerate frequently. Organics that sit on the bed too long migrate into the resin matrix and become hard to strip, so we program tannin systems to regenerate every few days rather than stretching capacity. When the resin eventually wears out after years of service, the tank rebeds with \u003ca href=\"\/products\/tannin-resin\"\u003ereplacement tannin resin\u003c\/a\u003e rather than replacing the whole system.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Installation Order\u003c\/h3\u003e\n\u003cp\u003eTannin resin works best on clean, softened water.

Hardness fouls anion resin, so a softener upstream extends resin life and improves tannin removal.

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.

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.

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.

SBACR-HP is an \u003cstrong\u003eacrylic\u003c\/strong\u003e gel resin with an open aliphatic structure that takes organics up AND releases them efficiently every regeneration. That is the difference between a tannin system that works for years and one that quits in a season.

Check Before You Buy\u003c\/h3\u003e\n\u003cp\u003eYellow water has two common causes, and they need different equipment. Fill a clear glass and let it sit overnight: if the color settles to the bottom, it is likely iron or sediment; if the water stays uniformly tinted, it is dissolved organics (tannins). Labs report the parameter as \"Tannin-Lignin.\" If your test shows meaningful iron alongside low tannins, treat the iron first - read our guide to the \u003ca href=\"\/blogs\/faqs\/types-of-iron-in-well-water\"\u003etypes of iron in well water\u003c\/a\u003e, or confirm with a \u003ca href=\"\/products\/tannins-water-test-kit\"\u003ecertified lab tannin test\u003c\/a\u003e before spending on equipment.\u003c\/p\u003e\n\n\u003ch3\u003eRuns Like a Water Softener\u003c\/h3\u003e\n\u003cp\u003eThe system meters your water use and regenerates the resin with a sodium chloride brine, exactly like a water softener.

Organics that sit on the bed too long migrate into the resin matrix and become hard to strip, so we program tannin systems to regenerate every few days rather than stretching capacity.

The catch is the resin chemistry: traditional styrene-based anion resins grab organics but do not let go of them well, so the bed fouls and performance fades. SBACR-HP is an \u003cstrong\u003eacrylic\u003c\/strong\u003e gel resin with an open aliphatic structure that takes organics up AND releases them efficiently every regeneration. That is the difference between a tannin system that works for years and one that quits in a season. The HP designation means the resin carries the \u003cstrong\u003eWQA Gold Seal\u003c\/strong\u003e certification to NSF\/ANSI-61 for potable water use.\u003c\/p\u003e\n\n\u003ch3\u003eTannins or Iron? Check Before You Buy\u003c\/h3\u003e\n\u003cp\u003eYellow water has two common causes, and they need different equipment. Fill a clear glass and let it sit overnight: if the color settles to the bottom, it is likely iron or sediment; if the water stays uniformly tinted, it is dissolved organics (tannins). Labs report the parameter as \"Tannin-Lignin.\" If your test shows meaningful iron alongside low tannins, treat the iron first - read our guide to the \u003ca href=\"\/blogs\/faqs\/types-of-iron-in-well-water\"\u003etypes of iron in well water\u003c\/a\u003e, or confirm with a \u003ca href=\"\/products\/tannins-water-test-kit\"\u003ecertified lab tannin test\u003c\/a\u003e before spending on equipment.\u003c\/p\u003e\n\n\u003ch3\u003eRuns Like a Water Softener\u003c\/h3\u003e\n\u003cp\u003eThe system meters your water use and regenerates the resin with a sodium chloride brine, exactly like a water softener. Your only routine job is keeping \u003cstrong\u003ewater softener salt\u003c\/strong\u003e in the brine tank. One tannin-specific rule: regenerate frequently. Organics that sit on the bed too long migrate into the resin matrix and become hard to strip, so we program tannin systems to regenerate every few days rather than stretching capacity. When the resin eventually wears out after years of service, the tank rebeds with \u003ca href=\"\/products\/tannin-resin\"\u003ereplacement tannin resin\u003c\/a\u003e rather than replacing the whole system.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Installation Order\u003c\/h3\u003e\n\u003cp\u003eTannin resin works best on clean, softened water. The proven residential order is: \u003ca href=\"\/products\/20-inch-big-blue-sediment-filter-kit\"\u003esediment pre-filter\u003c\/a\u003e → iron filter (if iron is present) → \u003ca href=\"\/collections\/residential-water-softeners\"\u003ewater softener\u003c\/a\u003e → \u003cstrong\u003etannin system\u003c\/strong\u003e → house. Hardness fouls anion resin, so a softener upstream extends resin life and improves tannin removal. One honest heads-up most sellers skip: anion exchange also removes some alkaline ions, so treated water typically drops about a point of pH.
