We recommend a licensed plumber. A plumber typically completes all four stages in 4 to 6 hours. Aidan supports your plumber by phone at 800-460-5810; send him your water test and a photo of your utility area before the install.

Installation Order (From Well to House)

  1. Pressure tank (your existing tank)
  2. Sediment filter (Big Blue housing), always first
  3. Iron filter and acid neutralizer, in the order Aidan sets from your water test (it depends on your pH)
  4. Water softener, always last, so it removes the hardness the calcite adds

Loading the Media

Every tank ships empty. Your plumber pours the Katalox Light into the iron filter tank, the three bags of calcite into the neutralizer tank and the resin into the softener tank through the included funnels, then mounts the valves.

Electrical Requirements

Two valves need power: the iron filter and the water softener, each from a standard outlet. The acid neutralizer and the sediment filter need none.

Drain Requirements

The iron filter and the softener each need a drain: a floor drain, utility sink or standpipe. Drain tubing is not included; your plumber sizes the iron filter's line for its backwash flow and run length, and the softener uses 1/2 inch tubing.

Space Planning

Plan for roughly 6 feet of wall: the iron filter tank is 13 inches across, the neutralizer and softener tanks 10 inches, plus the softener's brine tank and the wall-mounted Big Blue housing.

Start-Up

Aidan walks your plumber through the valve settings by phone: the softener's hardness setting and the iron filter's backwash, which he lengthens if the well delivers less than about 10 GPM.

Sediment Filter About every 4 to 6 months

  • Replace the 5 micron cartridge when it is dirty or the flow drops: about every 4 to 6 months on a typical well, up to 12 on a clean one. Unscrew the housing with the included wrench, swap the cartridge and reinstall it.

Iron Filter Minimal

  • The Fleck 2510AIO backwashes on its own. No salt, no chemicals, no cartridges. The Katalox Light lasts about 6 to 8 years before it is replaced.

Acid Neutralizer Check yearly, top off about every 18 to 24 months

  • Once a year, shine a flashlight behind the tank to see the calcite level. Top it off through the fill port when it is about halfway down. Calcite is never replaced, only topped off. Calcite comes in 50 lb bags.

Water Softener Keep salt in the brine tank

  • The Fleck 5600SXT regenerates by the gallons you use, with a 14-day override, using about 7 pounds of salt each time. Keep salt in the brine tank.

Why a 4-Stage System for Smaller Homes?

Same Problems. Right-Sized Solution.

If your well has iron, low pH and hard water at the same time, all three need treating, with a sediment filter in front. This package is built for a smaller household: 1 to 2 people on water with a pH of 6.0 to 6.9. The 1.5 cubic foot acid neutralizer is the size Aidan puts on two people at pH 6; with 3 or more people, or a pH below 6.0, text him before you order, because the neutralizer needs to be the 2.5. The iron filter is the 2.5 cubic foot Katalox Light unit, rated for up to 30 ppm iron, 15 ppm manganese and 10 ppm hydrogen sulfide, and the 48,000 grain softener handles 1 or 2 people on water up to about 30 grains per gallon, including the hardness the calcite adds. Every mineral tank is a Vortech tank and ships empty; the media comes in separate bags and is loaded at install, and drain tubing is not included. We recommend a licensed plumber; Aidan supports your plumber by phone at 800-460-5810. Free freight to the lower 48 states.

Frequently Asked Questions

The acid neutralizer. Its 1.5 cubic feet of calcite is the size Aidan puts on 1 to 2 people at pH 6.0 to 6.9. With 3 or more people, or a pH below 6.0, the neutralizer needs to be the 2.5 cubic foot size, so text Aidan your water test before ordering. The other stages have room to spare: the 2.5 cubic foot iron filter is rated for up to 30 ppm iron, 15 ppm manganese and 10 ppm hydrogen sulfide, and the 48,000 grain softener handles 1 or 2 people on water up to about 30 grains per gallon.

It depends on your water test. If you have iron, low pH, and hardness (the most common combination in well water), then yes. If you only have one or two of these problems, you might only need 2-3 stages. Call Aidan at 800-460-5810 with your water test results and he will tell you exactly which stages to keep and which to skip.

This package treats sediment, iron, low pH and hardness. It does not disinfect. If your water test shows coliform or E. coli bacteria, you need UV as well: add a UV system at the end of the line, or choose the 5-stage package with UV. A carbon filter is optional, for taste. Text Aidan your test and he will tell you whether you need either.

Yes, both are easy to add. The carbon filter goes after the softener (no power or drain needed) and the UV goes last in the line. We sell both as standalone systems that plumb right into the existing treatment line with standard 1-inch connections.

We recommend installation by a licensed plumber; Aidan supports your plumber by phone at 800-460-5810, 7 days a week. With 4 stages, a licensed plumber typically needs 4 to 6 hours. Every tank ships empty, so the plumber also loads the media. The sediment filter goes first and the softener last; Aidan sets the order of the iron filter and the neutralizer from your water test.

You can upgrade one stage without replacing the rest. The neutralizer is the first stage to outgrow: 3 or more people need the 2.5 cubic foot size. The softener steps up to 64,000 grain at 5 or more people, or at 3 or more people on water over about 15 grains per gallon. Text Aidan and he will tell you what changes.

Why a 4-Stage System Costs More

Professional Components vs. Budget Alternatives

What You Get With Budget Systems

Budget 'whole house' filter bundles often use undersized tanks, cheap cartridge-based iron removal that clogs in weeks, timer-based softener valves that waste salt, and partial media fills that need immediate topping off. They also rarely include an acid neutralizer at all, leaving your pipes to corrode even after the iron is filtered out.

Most sellers offer limited or no support. When you are connecting 3 or 4 systems and need to know which goes first or how to program the valve, you are on your own.

The Real Cost Comparison

Budget 'Whole House' Bundle
$2,000-3,500
  • ❌ Lifespan: Fails in 3-4 years
  • ❌ Result: Frequent repairs, poor water quality, leaks
  • ❌ Support: None
$0.90-1.20/day (shorter component life, frequent replacements)
Best Long-Term Value
Our Small Home System
$5,150
  • ✅ Lifespan: Lasts 15+ years with routine media replacement
  • ✅ Result: Done right the first time, peace of mind
  • ✅ Support: Lifetime USA Support
$0.47/day over a 30-year system life

At today's prices these four systems cost $6,380 bought separately: the 20 inch Big Blue kit $195, the 2.5 iron filter $2,895, the 1.5 acid neutralizer $1,295 and the 48,000 grain softener $1,995. This package is $5,150, a saving of $1,230, with the four stages sized to work together.

What You Get With Our System

This package uses a Fleck 2510AIO air-injection iron filter with 2.5 cubic feet of Katalox Light, a Clack C1190 non-backwashing acid neutralizer with 150 pounds of calcite, a Fleck 5600SXT metered softener with 10% crosslink resin (a tougher grade than standard 8%), and a 20 inch Big Blue sediment filter. All three mineral tanks are Vortech tanks.

You also get Aidan by phone and text 7 days a week: before the purchase, while your plumber installs it, and for the life of the system.

1-Year Risk-Free Guarantee

Sized for Small Homes, Backed for Life

If this 4-stage system fails to solve your well water problems within 30 days of installation, contact us and we will work with you to resolve the issue. Whether that means troubleshooting your setup, adjusting valve programming, replacing a component, or issuing a full refund. No shipping heavy equipment back. No restocking fees. No runaround.

10,000+ Systems Installed
455+ Verified Reviews

After 29+ years selling and supporting water treatment systems, we know which components work together and how to size them for smaller homes. This is not a one-size-fits-all bundle. It is configured for households of 1 to 2 people on private wells with iron, low pH (6.0 to 6.9) and hardness.

The Industry "Return Policy" Trap +

Most online retailers offer a return policy that requires you to ship everything back at your expense. For a 4-stage system on a pallet, that is $300-400 in return freight alone. Then a 15-25% restocking fee on top. It is designed to make returns impractical.

How Our Real Guarantee Works
1
The System Doesn't Fix Your Water

If your water test still shows problems after installation, that is on us.

2
You Call Us, We Fix It

We troubleshoot with you: water test results, installation order, valve settings, flow rates.

Full Refund, No Hassle

If we cannot resolve the issue, you get a full refund. We handle the logistics. You do not ship anything back.

Aidan

This is what I recommend for smaller homes with the classic well water problems: iron, low pH, and hardness. You do not need a 6-stage system if bacteria is not an issue and your taste is fine after the iron comes out. Call me with your water test and I will confirm if this is the right fit or if you should size up.

Solved my very high iron issues

"I had well water with over 20 ppm ferrous and 7 ppm of ferric iron, plus manganese and some sulfur. Local water companies rejected me, said they couldn't help. I purchased two Fleck 2.5 cu. ft. 2510AIO iron filter tanks with Katalox-Light. Problem solved."

Corrosive water resolved

"New house, brass fittings on my Pex were all corroding. Tested the water, acidic at 5.5. Found Mid Atlantic Water YouTube videos which were very helpful, ordered the non-back washing 2.5. Easy install, water tests great now."

Amazing set up

"Straight forward installation. In, out, and the drain. Ran a back wash cycle then put it online and it works GREAT. Cleaned out the iron and raised the pH to 7.5. Culligan tried to sell me something twice the price."
