Protect your plumbing, fixtures, and appliances from corrosive acidic water.
Acidic water corrodes pipes, stains fixtures blue-green, damages water heaters, and shortens appliance life. The RoyalSoft Acid Pro uses high-efficiency marble calcite media for maximum pH neutralization — raising your water's pH to a safe, neutral level with no drop in flow rate. NSF/ANSI 44 & 372 certified, Built in U.S.A., and designed for residential or light commercial use. Schedule your free in-home water test to find out if acidic water is damaging your home.

The RoyalSoft Acid Pro delivers neutralized, pH-balanced water to every tap, fixture, and appliance in your home simultaneously. With flow rates up to 20 gpm and 1″ ports that create zero drop in PSI, the system handles whole-home residential or light commercial demand. Available in two sizes: 10×54 (1 cu. ft. calcite) and 13×54 (3 cu. ft. calcite).
The bright, easy-to-read LCD display gives you full visibility into your system status at a glance. The RevV valve offers four advanced programming options with fully adjustable backwash and cleaning cycles — minimizing water usage during each cycle. Settings are stored in long-term memory, with a 72-hour backup to protect against power outages.
The patented RoyalSoft ceramic discs are diamond-hard — they won't wear out like traditional seals, spacers, and pistons. Corrosion and abrasion resistant, they ensure many years of worry-free operation with virtually no maintenance. Backed by a Lifetime Guarantee on wear parts.
The Acid Pro uses premium marble calcite media — a natural, NSF-approved mineral that dissolves at a controlled rate to raise pH and reduce the corrosivity of acidic water. As water passes through the calcite bed, the media gradually neutralizes pH to a safe, balanced level without over-correcting or introducing chemicals into your water supply.
Acidic water eats through copper and metal pipes, causing pinhole leaks and costly plumbing repairs. The Acid Pro raises pH before water touches a single pipe — stopping corrosion before it starts.
That distinctive blue-green staining on sinks, tubs, and fixtures is dissolved copper from corroded pipes. Neutralize your water's pH and those stains stop appearing — permanently.
Water heaters, dishwashers, and washing machines suffer accelerated wear when exposed to acidic water. Balanced pH water means less internal corrosion, longer service life, and fewer repair bills.
Low-pH water can leach metals from plumbing into your drinking water. The Acid Pro ensures the water reaching your tap is balanced, clean, and safe for the whole family.
The Acid Pro uses marble calcite — a natural mineral — to neutralize pH without adding any chemicals to your water supply. No salt, no brine discharge, and no harsh additives entering your drain or local waterways.
By replacing traditional seals and pistons with ceramic discs, we eliminate the need for replacement parts over the life of the system — reducing manufacturing waste and keeping more plastic out of landfills.
Clean Water Pro is committed to responsible water treatment. The RevV valve's adjustable backwash cycles minimize water usage with each cleaning cycle, and the Acid Pro's NSF/ANSI certifications ensure it meets stringent global standards for safety and performance.

Do I need a water neutralizer?
If your home has acidic water (pH below 7.0), a neutralizer is strongly recommended. Acidic water is corrosive — it slowly dissolves copper pipes, eats through fixtures and fittings, damages water heaters, and can leach metals into your drinking water. A neutralizer stops that damage before it starts. A free in-home water test from Clean Water Pro will confirm your pH level and tell you exactly what your water needs.
How do I know if my water is acidic?
The most reliable way is a water test — Clean Water Pro offers a free in-home test that measures your exact pH level. There are a few telltale signs with low pH: blue-green staining on sinks and tubs, pinhole leaks in copper pipes, a metallic or bitter taste in your water, or corrosion around faucets and fixtures. Any of these is a strong indication that your water's pH is too low.
What are the signs of acidic water?
The most visible sign is blue-green staining — that distinctive teal discoloration you'll see on sinks, tubs, and shower floors is copper residue leaching out of corroded pipes. Other signs include pinhole leaks in copper plumbing, a metallic taste in your tap water, greenish buildup around faucet aerators and drain openings, and premature failure of water-using appliances like water heaters and washing machines.
Is low pH water dangerous?
Consistently drinking water with a very low pH can be a health concern, particularly because acidic water tends to leach metals — including copper and lead — from your plumbing as it travels to your tap. Elevated copper and lead levels in drinking water are associated with serious health risks over time. Neutralizing your water to a safe, balanced pH eliminates this risk and gives you confidence in the water your family drinks every day.
Why do I have blue-green stains in my sink?
Those stains are dissolved copper — and they're a direct sign that your water is acidic. When water with a low pH flows through copper pipes, it slowly dissolves the pipe material, carrying copper particles along with it. When that water sits in your sink or tub, the copper oxidizes and leaves behind that distinctive blue-green residue.
Do I need a neutralizer and a softener?
It depends on your water test results — and that's exactly why we test first. Many homes in Westchester, Putnam, and Dutchess County deal with both acidic water and hard water at the same time, in which case both systems are recommended. The Acid Pro is typically installed first (at the point of entry) to raise pH, followed by the RoyalSoft softener to remove hardness minerals. The two systems work together seamlessly — and your Clean Water Pro expert can size and configure both in a single installation visit.
How big of a neutralizer do I need?
The right size depends on your household's water usage and flow rate requirements. The RoyalSoft Acid Pro is available in two configurations: the 10×54 (1 cu. ft. of calcite media, 18 gpm flow rate) for most standard residential applications, and the larger 13×54 (3 cu. ft. of calcite media, 20 gpm) for higher-demand homes or light commercial use. Your Clean Water Pro expert will assess your flow rate, pipe size, and water usage during your free in-home consultation and recommend the right fit.
