Are your pipes constantly leaking or corroding mysteriously? Does your water taste sour or leave a metallic aftertaste on your tongue? These are hallmark signs of acidic, low-pH water infiltrating your home—a silent culprit that steadily erodes plumbing, corrodes fixtures, and risks costly repairs. Beyond damaging property, drinking water with a low pH level can cause discomfort, skin irritation, and an unpleasant household water experience.

The system that fixes it

The C-Series Acidic / Low-pH Water System is engineered precisely to combat and neutralize acidic water before it harms your home and your health. At its core lies the C-Series backwashing control valve, a premium head valve designed to automate maintenance with efficiency and reliability. This valve meticulously manages the system’s backwash cycles, flushing out spent media and preventing clogging, ensuring your water treatment remains consistent and flawless over time. Unlike generic valves, this genuine, serviceable brand valve promises straightforward access for servicing and replacement, safeguarding long-term investment and peace of mind.

The system is built upon an upflow calcite tank that optimizes the treatment process by maximizing contact between your water and the media. Inside, a precisely calibrated blend of calcite infused with Corosex media gently dissolves into your water, raising its pH to neutral levels. This targeted neutralization halts corrosion and stops acidic water from eating away at pipes, faucets, and fixtures.

How the media works

The heart of this system’s success lies in its carefully chosen media: a combination of calcite and Corosex. Calcite, a natural calcium carbonate mineral, gradually dissolves into the water, gently increasing its pH level to neutralize acidity. Paired with Corosex—a specialized media that provides a controlled release of magnesium oxide—the blend ensures the water’s pH doesn’t just stabilize but truly balances out. This slow, steady process prevents sudden pH swings, protecting your pipes from aggressive corrosion and halting the sour taste and odors caused by acidic water. Essentially, your water flows through this media bed and emerges healthier, more neutral, and safe for your entire household.
