United StatesWell made, simple install
This was very simple and straight forward to install. It works as it should and raised my ph level from 6.0 to 7.0.
United StatesInstallation 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,
United StatesCouldn’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!
United StatesLow 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!!
United StatesJust What We Needed
Very good. Pretty easy to install if you have all parts/adapters on hand. Finally, we can drink our water from the tap!
United StatesWish I did this sooner!
Piece of cake, Thanks for the help folks.
United StatesPricey, 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.
United StatesBest 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

Shipment, installation and everything went smoothly and is going perfectly

Product was delivered promptly and installed easily. Nice not to worry about future damage to the copper pipes. Mid Atlantic answers the phone when you call.
1-Year Risk-Free Guarantee
After 30 years of testing acidic water solutions, the data led us to this exact system. With a track record of 1,000+ successful homeowner installations (DIY or Licensed Plumbers), we have the evidence to offer a true risk-free guarantee based on results, rather than an empty marketing gimmick.
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.
If the system does not neutralize your pH as promised.
You'll work directly with the expert who designed your system to ensure it's set up correctly for your specific well chemistry.
If it still doesn't solve the problem, we refund you entirely.
No return shipping required.
Not sure if this is the perfect system? Don't guess. If you aren't 100% sure this is the correct size for your well, text me your water test or call me directly. I'll personally review it.
We're still gathering reviews for this one.
Honest answer: this product is too new for individual reviews to exist yet. So instead of pretending, here is what 10,000+ homeowners say about the rest of the systems we sell, same team, same support, same 29-year track record you'll get with this product.
"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."
"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."
"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."
"Three contractors and two other suppliers reviewed my well report. Quotes ranged from $5,000 to $10,000. Then I found Mid Atlantic. Aidan reviewed the report and recommended a complete system. Same equipment, fraction of the cost, and the support was real."
"Easy, bullet-proof installation. No moving parts. Raised my pH from 6.8 to a perfect 7.6. I had previously installed the same unit in my daughter's water system. Her pH was 5.2. Following Aidan's videos, both installs went smoothly."
"Super easy install. Shouldn't have to service it for approximately 24-36 months based on my water usage. Tank is solid, fittings are clean, no leaks. Exactly what was advertised."
