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!!
Just 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!
Wish I did this sooner!
Piece of cake, Thanks for the help folks.
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
Shipment, installation and everything went smoothly and is going perfectly
Acid Neutralizer
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.
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.
