Eliminate damage from acidic water. Balance pH with Corrosion Shield.


Eliminate acidic water with Corrosion Shield™

Acidic water is extremely corrosive and can cause detrimental plumbing damages and incur astronomical repair costs. Furthermore, acidic water also leaches heavy metals from eroding pipes, exposing your water to copper, zinc, and even lead. For many well owners across the country, acidic water is a serious water quality problem.

Corrosion Shield from U.S. Water is a metered pH Balancing System which injects the precise amount of neutralizer into the water stream regardless of the flow rate.

What is acidic water?

Acidic water is any water with a pH value of 6.5 or less. pH is measured on a scale between 1 and 14, with 7 representing the neutral value.

Acid water occurs naturally, as rain falls to earth soft and slightly acidic. As it absorbs minerals and dissolves solid materials, the pH of the water can rise. Water with a pH value higher than 7.5 is considered basic, or alkaline.

What causes acidic water?

Water becomes acidic when it combines with carbon dioxide during the process of precipitation. During the hydrologic cycle, water from sources like the ocean, lakes, and streams evaporate.As the moist air rises, it cools and condenses into water vapor, creating clouds. This process is a natural form of water filtration.

When water evaporates, it is stripped of water hardness, bacteria, and minerals. The water distillation process mimics this principle to purify water. Since all of the minerals have been vaporized, this water is now soft and acidic.

The metered system delivers precise pH adjustment

This precision injection system neutralizes the pH at any flow rate – high or low. How does it work?

  1. First, your home’s water enters through the Meter which measures the flow rate. (See system diagram above)
  2. Secondly, the Electronic Injection Pumpresponds to the meter data and injects potassium carbonate from the tank into the water stream. ThisPumpmounts near the tank for easy accessibility.
  3. Finally, the water then flows through the Mixer, which ensures a consistent blend for perfectly balanced water as it flows into your home’s water system.


Rent our equipment hassle-free!

Our rental options cover all equipment, a trouble-free maintenance agreement, plus all filter media for the rental term.

Corrosion Shield’s “smart meter” automatically adjusts to maintain precise pH level

SMART Injection System vs Calcite Neutralizer System

Another option for treating low pH in your home’s water is a calcite neutralizer system.
While both systems can initially adjust your pH to desired levels, the Injection pH Balancing System is more effective at rapidly adjusting the pH of acidic water and maintaining a steady pH level over the long-term.
