🛠️ DIY Installation

Installing the system yourself? You will need to purchase the necessary plumbing supplies (such as PVC, PEX, or SharkBite fittings and pipe) from your local Lowe's or Home Depot to connect the unit to your home's main water line. Need guidance? View our Interactive Install Guide. Plus, our technical support team is available 7 days a week, even on weekends, to help you get the job done right.

Estimated Cost $125 Parts & Supplies Only

Easy to move indoors: The equipment tank is relatively light when empty. Your calcite media arrives separately in five easy-to-manage 50 lb bags. Simply carry the components inside one by one and fill the tank in place. There is no heavy lifting beyond the 50 lb bags.

👨‍🔧 Hire a Plumber

Prefer a hands-off approach? You can hire a local licensed plumber to handle the installation. They will typically provide all the required pipes, fittings, and expertise to ensure the system is connected cleanly and up to code.

Estimated Cost $400 - $800 Professional Labor & Parts
Non-backwashing, no drain line, no electricity. Installs directly into your main water line with standard 1″ threaded connections. Designed for straightforward DIY installation.

Vortech® Technology uses a patented internal distributor system to maximize media contact, reduce channeling, and deliver consistent treatment across the entire tank.

The result is higher efficiency, longer media life, and reliable performance without unnecessary complexity or wasted capacity. Built for real-world conditions and proven across thousands of installs.

Frequently Asked Questions

No, about 80% of our customers install this system themselves. If you are comfortable cutting pipe and using a wrench, you can do this. The system comes with a bypass valve and threaded connections that make it straightforward. We also provide a comprehensive video guide and have tech support available 7 days a week if you get stuck.

Because of our larger 2.5 cubic foot tank size, you only need to add media every 6 to 12 months for the average household (3-4 people). Smaller units from big box stores often require refilling every 3-6 months. We include a fill funnel with your order to make the refill process mess-free.

Not noticeably. The "Vortech" tank technology we use actually improves flow rates compared to traditional gravel-bed tanks. The system is rated for 17 GPM (Gallons Per Minute), which is sufficient for most homes with up to 3 bathrooms running simultaneously.

The unit ships via freight truck with liftgate service. The driver will lower the pallet to your driveway or curb. You are responsible for disposing of the wooden pallet and cardboard packaging. The tank itself is lightweight when empty (~25 lbs) and easy to move into your garage or basement before filling it with the included media.

No, it's a non-backwashing head. It doesn't need electricity or a backwash line.

Installation of an Acid Neutralizer

I was pleased at how quickly the tank arrived. My plumber had only two questions for Mid Atlantic Water. Installation went smoothly. Before installation, my average Ph was 6.20. After installation, so far, the Ph has been 7.99, which is higher than I expected. Hopefully, this new acid neutralizer tank will arrest the acid corrosion from my well water that had caused leaks to three PEX brass joints,

Couldn’t be better!

I’ll start by saying that the customer service offered my Mid Atlantic Water was outstanding! I had multiple questions answered from prepurchase through installation. I installed myself fairly easily and it 100% fixed my acidic well water issue. It took my 5.5ph well water to 7.2 using the 2.5cf non backwashing (with no flow mag). It took my tds from 25 to 135 so no worries there either. Thank you so much for all of the help and delivering a product that works!

Low PH fixed

I have nothing but great things to say about this company. I’ve called and emailed and each time was treated with professionalism by the owner himself. That’s right, the owner, answered the phone and even responded to an email on a Saturday. Easy installation and raised my PH from 5.5 to 7.5!! Super pleased and highly recommended!!

Very good. Pretty easy to install if you have all parts/adapters on hand. Finally, we can drink our water from the tap!

Pricey, but worked as expected

My column is in a corner, and tall enough to be awkward to refill. This funnel fit well, stayed in place and had a big enough throat to fill the column quickly.

Best Option East of the Mississippi

Purchased this Clack 2.5 because it has a side fill port (a dream option for someone who had to disassemble entire head abomination just to add medium in old tank). Bought from Mid Atlantic because they have so many useful videos online about water treatment tanks and installation. Whole operation was a breeze; I ordered on a Sunday night, shipping from multiple states away -- arrived within a few days & everything was installed (by me, alone) and up and running by the following Saturday morning (6 days total). The calcite treatment medium sold by Mid Atlantic is far better than the dusty stuff available from my local plumbing supply. 5-Star ***** Review from me! Dan @ Cape Cod

acid neutralizer tank

The tank works well, but it is hard to find fittings to plumb it in. Home depot and lowes in our area did not have the fittings, and I finally found them at a plumbing store located over an hour away. Please send some fitting to hook up to pex or copper, not these garden hose fittings.

Investing in The Right System

Many systems look identical online, but cheaper options often cut corners.

Found this neutralizer cheaper somewhere else?
  • Many Amazon and discount sellers use similar photos and product titles.
  • The system may look similar at first glance.
  • But to advertise a lower price, key components are often downgraded or removed.
  • Cheap systems commonly use thinner tanks, less filtration media, and provide little to no technical support.
  • When something goes wrong, you're usually on your own.
  • This is the best price we can offer without cutting quality or support.

The True Cost Over Time

Cheap Alternative
$800 Upfront
  • Lifespan: Fails in 3-4 years
  • Result: Frequent repairs, poor water quality, leaks
  • Support: None

Our Premium System
$1,495 Upfront
  • Lifespan: Lasts 15+ years
  • Result: Done right the first time, peace of mind
  • Support: Lifetime USA Support
~ $0.27 / Day

Do it right the first time. By investing a little more upfront, you prevent early replacement costs, plumbing repair headaches, and the frustration of poor water quality. This is without a doubt the best long-term option for your home.

What You're Actually Paying For
  • No Media Skimming: We provide the exact optimal amount of the highest grade media. Competitors frequently underfill tanks by 20-30% to cut costs, severely reducing your system's effectiveness.
  • Premium Structural Tanks: Our systems utilize heavy-duty, pressure-tested USA vortech structural tanks built to last decades, preventing cracked tanks and flooded basements.
  • Genuine Warranties: Discount retailers are often selling tanks imported overseas, meaning less structural integrity and no warranty. Our tanks carry full manufacturer backing with a 10 year warranty. We've tried tanks from Mexico in the past to reduce cost for our customers and all it did was create problems.
  • Lifetime USA Tech Support: With over 30 years of industry experience, we actually pick up the phone. We provide tech support 7 days a week between 8AM - 5PM EST.

The Industry "Return Policy" Trap +

Most water filter companies offer standard "Money Back Guarantees" or return policies fully knowing that you aren't going to drain, package, and pay heavy freight costs to ship a 600lb wet tank back to them. It's an illusion of safety. Our guarantee requires zero return shipping.

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."
