When your home’s water runs acidic, it’s more than a minor inconvenience—it’s a hidden threat. Low-pH water quietly erodes your pipes, leaving behind pinhole leaks, stained fixtures, and metallic tastes in your drinking water. Over time, this corrosive water can lead to costly repairs, reduce the lifespan of appliances, and even impact your family’s health and comfort. Ignoring acidic water means accepting ongoing damage, but solving it restores peace of mind and protects your home’s foundation.

The system that fixes it

The Pentair Acidic / Low-pH Water System is engineered to neutralize corrosive water before it harms your plumbing and home. At its core is the Pentair-series backwashing control valve, a robust, serviceable valve designed to regulate water flow and initiate automatic cleaning cycles, ensuring consistent performance and longevity. Unlike generic valves that often require full replacements when malfunctioning, this genuine Pentair valve lets certified technicians service and maintain the heart of your system, saving money and downtime. The system’s backbone is a sturdy upflow calcite tank filled with a specialized blend of calcite and Corosex media. This media gently dissolves into the water, elevating pH levels just enough to halt corrosion without altering your water’s natural balance.

How the media works

The heart of this system’s effectiveness lies in its finely tuned media blend of calcite and Corosex. Calcite is a gentle mineral that dissolves into water, naturally raising its pH and neutralizing acidity. Corosex complements this process by accelerating the calcite dissolution, ensuring that even highly acidic water receives proper treatment. As water flows upward through the tank, it slowly interacts with the media, balancing out the acidity without harsh chemicals or drastic changes. This thoughtful design means that corrosive elements are neutralized before they can damage pipes, eliminating the root cause of the problem rather than masking symptoms.

Common questions

Q? How does acidic water damage my home if it looks clear?

A acidic or low-pH water is often clear and odorless but aggressively dissolves metal through corrosion. This leads to hidden pipe leaks, rust stains, and damage that can be costly over time.

Q? Will this system change the taste or smell of my water?

A The Pentair Acidic / Low-pH Water System raises pH gently without adding chemicals or altering natural water properties, improving taste by removing metallic flavors caused by acidity.

Q? How often will I need to maintain or service the system?
