When corrosive water runs through your home’s plumbing, it’s more than just an inconvenience — it’s a costly threat. You might notice blue-green stains on sinks and fixtures, pinhole leaks springing up in pipes, or a metallic taste in your drinking water. Left unchecked, this aggressive water can eat away at your solder joints and pipe walls, causing leaks, reduced water flow, and expensive repairs that chip away at your home’s value and your peace of mind.

The system that fixes it

The C-Series Corrosive Water Damaging Pipes System is engineered precisely to neutralize aggressive, corrosive water before it wreaks havoc on your plumbing. At the heart of this solution is the C-Series backwashing control valve—a genuine, serviceable brand valve that automates the cleaning process, ensuring your system stays efficient and long-lasting. This control valve regulates water flow through an upflow calcite tank filled with a carefully balanced mix of calcite and Corosex media. This blend gently raises water pH levels, neutralizing acidity and protecting every inch of your pipes, solder, and fixtures from corrosion damage.

How the media works

The secret behind the C-Series system’s power is its carefully designed media blend inside the tank. Calcite is a naturally occurring mineral that gently raises the pH of acidic water, neutralizing its corrosive effects. Corosex, a specialized mineral blend, complements calcite by targeting particularly aggressive water conditions, boosting the neutralization process. Together in an upflow tank, water flows upward through this media blend, allowing maximum contact and treatment time. The result is water that is balanced, non-corrosive, and safe for all your plumbing, solder, and fixtures.
