How Much Does a Well Water Treatment System Cost? (Complete Price Breakdown)

A well water treatment system costs whatever your water test calls for, because each problem the test shows takes its own piece of equipment. From us, one piece for one problem runs $895 (a UV light) to $2,495 (a 2.5 cubic foot iron filter), shipped. Two problems as a package run $2,995 to $4,695, and our systems for three or more problems run $4,495 to $9,495. A licensed plumber adds about $800.
That is the cost of treating the water. Drilling a well, a new pump and the pressure tank are separate costs, and this page does not price them. Every price here is today's (October 2026), checked against our store the day it was written.
Quick Answer
Your water test sets the price. Each problem on it takes its own piece of equipment.
- One problem. One piece of equipment, $895 to $2,495 shipped. Most of our customers buy a $1,495 neutralizer for acidic water, a $2,495 iron filter or a $1,995 softener. See what each problem costs to fix.
- Two or more problems. Packages run $2,995 to $4,695 for two problems and $4,495 to $9,495 for three or more. See what two or more problems cost.
- The plumber. About $800 for 2 to 3 hours. Two tanks take 3 to 4 hours. We install nothing. See what a plumber charges.
- Upkeep. About $50 a year for a neutralizer, $100 of salt for a softener, and about $265 for a UV light (the $170 lamp plus about $95 of power). Iron filters need new media every 6 to 8 years, carbon filters every 4 to 5. See what it costs to run.
- Dealer quotes. The quotes callers read me this year for two or more systems ran $7,000 to $15,000. See why dealer quotes run higher.

What each well water problem costs to fix
Each problem on a well test has its own fix, and each fix has its own price. These are our prices today, shipped free to the lower 48. The media comes with the tank in separate bags and goes in at install.
| Your test shows | What fixes it | Our price | |
|---|---|---|---|
![]() |
Low pH (acidic water) | Acid neutralizer that raises the pH | $1,195 to $2,395 |
![]() |
Iron, manganese or a rotten egg smell | Iron filter (it uses air, no chemicals) | $2,095 to $3,295 |
![]() |
Hard water | Water softener | $1,495 to $2,495 |
![]() |
Bacteria (coliform or E. coli) | UV light, with a sediment filter in front | $895 to $995, plus $165 to $195 for the filter |
![]() |
Sand, silt or grit | Big Blue cartridge sediment filter | $165 to $195 |
![]() |
A chemical taste or odor | Carbon filter | $1,495 to $2,495 |
| Drinking water only, at the kitchen sink | Under-sink drinking water filter (reverse osmosis) | $275 to $595 |
Most of our customers buy the 2.5 cubic foot neutralizer at $1,495, the 2.5 cubic foot iron filter at $2,495 and the 48,000 grain softener at $1,995. For a coliform test, I put a 10 inch Big Blue ($165) ahead of the VH410 UV light ($995). A home with 3 or more people gets the 20 inch Big Blue ($195) instead.
Less common problems have their own systems: arsenic $3,495, nitrate $2,895, tannins $2,695, PFAS $2,495 and lead $1,895.
What two or more problems cost
Two problems means two fixes, and we sell the common combinations as packages. I set the order of the tanks from your test.
| Your test shows | Package | Price |
|---|---|---|
| Acidic water and hard water | Acid neutralizer and softener | $3,295 with the 2.5 neutralizer; $3,095 with the smaller 1.5 |
| Iron and hard water | Iron filter and softener | $3,695 with the 2.5 iron filter; $3,395 with the smaller 1.5 |
| A chemical taste and hard water | Sediment filter, carbon filter and softener (3 stages) | $2,995 |
| Rotten egg smell and bacteria | Sediment filter, iron filter, carbon filter and UV light (4 stages) | $4,495 |
| Iron, acidic water and hard water | Iron filter, acid neutralizer and softener | $6,285. For 1 or 2 people: the 4-stage small-home system, $5,150 |
| Every problem listed, plus bacteria | The full 6-stage system | $8,295. For big houses: the high-flow version, $9,495 |
Every package and pair is on our well water systems page, with the single tanks.

8 AM to 5 PM Eastern, seven days a week. A real person, not a call center.What a plumber charges to install it
We ship the equipment and install nothing, so you hire a licensed plumber and pay him directly. A standard install takes a plumber 2 to 3 hours and usually costs about $800. Depending on the plumber and the area, I give people $500 to $1,200.
Two tanks take a plumber longer, but they should not cost much more. A Maryland caller in September had plumbers quoting her almost $3,500 to $4,000 to put in an iron filter and a softener. I told her, "You shouldn't have to pay more than 700 to 1,000 dollars for the installation. It's only gonna take them, like, 3 or 4 hours at the most."
| Who puts it in | Labor cost | Time |
|---|---|---|
| A licensed plumber, one tank | About $800; $500 to $1,200 depending on the plumber | 2 to 3 hours |
| A licensed plumber, two tanks | About $700 to $1,000 | 3 to 4 hours |
| Owner-installed | No labor bill; you buy the fittings and drain tubing | Your own time |
A UV light on its own takes a plumber about an hour. We recommend a licensed plumber, and I answer your plumber's questions by phone at 800-460-5810.
What it costs to run each year
A neutralizer or a softener costs about $50 to $100 a year to run, and a UV light about $265 with its power. An iron filter or a carbon filter costs nothing in between: iron media lasts 6 to 8 years, carbon 4 to 5.
| System | What you buy | How often | Cost per year |
|---|---|---|---|
| Acid neutralizer, 2.5 cubic foot | A $145 bag of calcite mineral | About 3 bags in 10 years | $50 |
| Water softener, 48,000 grain (the common size) | Pellet salt, about $8 a 40 lb bag | A bag every 30 to 45 days in my house (3 people) | $100 |
| UV light | A new UV lamp: $170 (VH410) or $165 (VH200) | A lamp once a year; the light stays on around the clock | $165 to $170, plus about $95 of power (the VH410 draws 60 watts; U.S. average rate) |
| 20 inch Big Blue sediment filter | A $55 cartridge | About every 4 to 6 months | $110 to $165 |
| Iron filter, 2.5 cubic foot | New Katalox Light media, $875 a tank | Every 6 to 8 years | $0 in between |
| Carbon filter, 2.5 cubic foot | Two boxes of Centaur carbon, $590 | Every 4 to 5 years | $0 in between |
| Under-sink reverse osmosis (MAW-50) | Filters $49 to $59; a membrane $135 | Filters every 6 to 12 months; the membrane every 2 to 3 years | $50 to $120, plus a membrane every few years |
Over 10 years, the price plus the upkeep comes out like this. The plumber, paid once, is not in these totals, and neither is a $145 UV sleeve if yours stops coming clean.
| System | Price today | 10 years of upkeep | 10-year total |
|---|---|---|---|
| Acid neutralizer, Clack 2.5 | $1,495 | About $500 of calcite refills | About $1,995 |
| Carbon filter, Clack 2.5 | $1,695 | $1,180, two refills | $2,875 |
| UV light, Viqua VH410 | $995 | About $2,480: nine lamps ($1,530) and about $950 of power | About $3,475 |
| Water softener, 48,000 grain | $1,995 | About $1,000 in salt | About $2,995 |
| Iron filter, Fleck 2.5 | $2,495 | $875, one refill | $3,370 |

What makes one well cost more
Each problem adds a piece of equipment, so the number of problems sets most of the price. The size of the house and how bad the water is set the rest.
- How many problems. One fix per problem. A well with low pH, iron and hard water needs three tanks.
- The size of the house. Each tank comes in sizes. Non-backwashing neutralizers run $1,195 for a 1.0 cubic foot to $1,695 for a 3.5, iron filters $2,095 for a 1.5 to $3,295 for a 3.5, and softeners $1,495 for a 32,000 grain to $2,495 for an 80,000.
- How bad the water is. Very acidic water (pH below 5.5) needs FloMag mixed in with the calcite, which makes the 2.5 neutralizer $1,695 instead of $1,495. A caller in September had a pH of 4.9. I told her, "1,495, and then when it asks you to add Flowmag, pick yes."
- Backwashing or not. A backwashing 2.5 neutralizer is $2,195 against $1,495 for the non-backwashing one, and it needs a drain line.
- Who puts it in. A plumber charges about $800. A dealer's price usually folds its own install into the quote, as the next section shows.
Why dealer quotes run higher
A dealer's quote usually pays for the install, and often service visits, along with the equipment. The quotes callers read me this year for two or more systems ran $7,000 to $15,000. For one softener they ran $2,000 to $6,750.
A North Carolina caller in August had three companies quote $9,000 to $15,000 for a neutralizer, a softener and a UV light. From us, the 2.5 neutralizer and 48,000 grain softener package plus a VH410 UV light comes to $4,290, before about $800 for a plumber. That is comparable equipment, not the dealer's own brand.
A dealer does one thing we do not: it puts the system in and usually comes back to service it. If that is worth the difference to you, ask what the quote covers: each piece of equipment by name, the install, and what a service visit costs. One buyer wrote that RainSoft "charged me $280 twice a year to come and service and add calcite." If you have a quote in hand, is my water treatment quote too high walks through what those quotes include.
What buyers saved
These are verified purchases. The savings run from $400 to thousands, depending on the quote and the plumber.
| Buyer | Bought | What they wrote |
|---|---|---|
| A buyer, Apr 2026 Verified buyer | Iron filter, 1.5 cubic foot | "This system saved me thousands over what other companies recommended." |
| A buyer, Mar 2024 Verified buyer | Acid neutralizer, 2.5 cubic foot | "Our plumber installed it in ~3 hours. ... We saved ~$1500.00 including installation, by buying online and hiring a plumber to install it." |
| Mark W., Jan 2022 Verified buyer | Acid neutralizer, 2.5 cubic foot | "The total price of unit plus cost of plumber saved me $400 dollars over using a water treatment company in my zip code." |
| Mark H., Sep 2020 Verified buyer | UV system with filters | "Quotes ranged from $5,000 to $10,000. ... We saved thousands of dollars and our well chemistry report is now perfect." |
What the price does not include
You pay us only for the treatment equipment, shipped free to the lower 48. Nothing about the well itself is in the price. Every tank ships empty, with the media in separate bags that go in at install.
- The well. Drilling, the pump and the casing are a well contractor's work and price. We do sell well pressure tanks, $1,095 to $2,195; well pressure tank cost covers what a plumber charges to replace one.
- The plumber. About $800, paid to him directly.
- Drain tubing. A softener or a backwashing tank needs 1/2 inch tubing to a floor drain, a utility sink or a standpipe. Your plumber gets it at any hardware store.
- Pipe and fittings. Whatever connects the tanks to your line.
- Salt. For a softener, bought locally.
- An outlet. The UV light and every tank with a control valve plug in. The non-backwashing tanks need no power.
Frequently asked questions
How much does well water cost per month?
On a private well there is no water bill from a utility. Once a system is in, the upkeep is the monthly cost: a neutralizer and a softener together run about $150 a year, about $12 a month, and a UV light adds about $22 a month, lamp and power.
Can you treat your own well water?
You can keep it running yourself: salt for the softener, a new cartridge, the yearly UV lamp, a bag of calcite every few years. For the install we recommend a licensed plumber, and I answer your plumber's questions by phone. Test first, so you buy only the tanks your water needs.
How much does a well water chlorination system cost?
We don't sell a chlorination system. For bacteria in a well we use a UV light, $895 to $995, with a 5 micron filter ahead of it at $165 to $195. A UV light adds nothing to the water.
What is the best well water filter system for home use?
The one your test calls for, sized to your house. My pick for each test result is in which system is best for your well.
What are the downsides of water treatment?
Upkeep, space and a plumber's visit. A softener needs salt, a backwashing tank needs a drain line, a UV light needs a new lamp every year and an outlet, and each tank takes floor space where the water comes into the house.
