When your well water arrives acidic and loaded with hard minerals, your home pays the price in corrosion, scale buildup, and dingy fixtures. Pipes weaken and clog, appliances falter, and your skin and hair feel dry and uncomfortable. Every rinse wastes soap and effort, while costly repairs loom just beyond the surface.

The system that fixes it

The Pentair Acidic Water + Hard Water (Well) System is engineered for this exact dual challenge, delivering balanced, softened water that safeguards your entire home. At its core is the Pentair-series backwashing control valve, a precision-engineered head valve that automates the cleaning of media and ensures steady, reliable flow without interruptions or manual resets. This genuine brand valve is fully serviceable—meaning long-term dependability and simpler upkeep compared to generic units. The system is built around a robust calcite tank placed upstream of the softener, hosting a unique blend of calcite neutralizer media followed by softening resin. This two-step media action first raises the water’s pH to neutralize corrosive acidity, then removes hardness minerals to prevent scale buildup, protecting your plumbing and fixtures from damage.

• Pentair-series backwashing control valve automates media regeneration and maintains consistent water pressure
• Serviceable, brand-specific valve designed for easy maintenance and parts replacement
• Calcite tank positioned ahead of the softening stage to efficiently neutralize acidity before softening
• Dual-media blend: calcite neutralizer raises pH, softening resin removes hardness minerals
• System built for well water problems, addressing both acidity and hardness for full home protection

How the media works

The magic lies in the carefully balanced media blend inside the tank. First, the calcite neutralizer media gently raises the pH level of incoming water, effectively neutralizing its acidity. By stabilizing pH, it stops the corrosive effects that eat away at metal pipes and fixtures. Once the water’s acidity is balanced, it passes through the softening resin, which actively captures hard minerals like calcium and magnesium that cause scale buildup. This sequential media approach ensures your water not only feels smoother but also protects your home's plumbing system from the twin threats of corrosion and scale.

Common questions

Q? How does the system handle both acidity and hardness at the same time?
A The system uses a two-stage media blend: the calcite neutralizer raises the pH to eliminate acidic corrosion risks before the softening resin removes hard minerals that cause scale. This two-step treatment protects your home completely.

Q? What makes the Pentair-series backwashing valve better than other valves?
A This valve is a genuine Pentair product designed specifically for reliable backwashing and regeneration cycles. It is fully serviceable, meaning you can replace parts easily, extend valve life, and avoid costly downtime associated with generic valves.

Q? Can this system protect older homes with aging plumbing?
A Absolutely. The alkaline neutralization of acidic well water prevents further corrosion of old pipes, while the softening media stops scale buildup that can clog and damage plumbing over time, extending the lifespan of your entire water system.
