Every stage, explained

Sediment Pre-Filter: The journey to clean water begins with removing abrasive sand and grit that commonly hammer well pumps. This stage protects your pump and the rest of the system from abrasive damage, preventing costly repairs and downtime. The premium Pentair control valve ensures reliable filtration with easy maintenance, stopping sediment before it can wreak havoc.

Acid Neutralizer: Low pH water is corrosive, eating away metal plumbing and causing unsightly blue-green stains on sinks, tubs, and fixtures. This stage raises the water’s pH to a safe, balanced level. By neutralizing acids before other treatments, it preserves your home’s plumbing and prevents metal leaching. The Pentair-series valve provides precise control and durability tailored to this critical step.

Air-Injection Iron & Sulfur Filter: Iron and manganese cause rusty stains and sediment, while hydrogen sulfide creates that infamous rotten-egg smell. The air-injection technology oxidizes these contaminants, transforming them into particles that can be trapped and flushed out. This filter clears your water of both visible discoloration and foul odors, restoring freshness. The matched Pentair valve guarantees consistent operation and backwashing to keep the media clean.

Metered Softener: Hard water deposits scale inside pipes and appliances, reducing efficiency and lifespan. This stage uses a metered softening system that removes hardness minerals precisely when needed, conserving salt and water. Soft water means smoother soap lather, cleaner dishes, and appliances protected from scaling. The premium Pentair control valve integrates seamlessly, optimizing performance and regeneration timing.

Disinfection Stage: Well water can carry bacteria and odors that standard filtering cannot eliminate. The disinfection stage suppresses microbial contaminants and lingering smells, ensuring your water is not only clear but safe. Using the trusted Pentair-series control valve, this stage works quietly and effectively as the final barrier before water enters your home.

UV Disinfection Add-On: For those seeking chemical-free bacterial protection, the UV disinfection option delivers powerful sterilization by exposing water to ultraviolet light. This process kills bacteria, viruses, and harmful cysts without adding chemicals, making your water safer and fresher to drink. Easily integrated into the Pentair platform, it complements the system perfectly.

Under-Sink Reverse Osmosis Add-On: Bottled-quality drinking water right at your faucet is possible with the under-sink RO system. It filters out dissolved solids and impurities that other stages can’t catch, providing crisp, clean taste and peace of mind. This optional Pentair unit works flawlessly after the whole-house treatment, delivering purified water exactly where you want it.

Why the install order matters

The order in which these stages are installed isn’t random—it’s a carefully engineered sequence to maximize effectiveness and longevity. Acid neutralization comes first to protect pipes and prevent corrosion. Then the iron and sulfur filter removes minerals that would foul the softening resin. Softening follows, preventing scale buildup in your plumbing and appliances. Finally, disinfection—plus optional UV—cleanses water of bacteria and odors. If you add reverse osmosis, it goes last, providing the purest drinking water. This measured sequence ensures each stage performs optimally without interfering with the next.

Why one brand

This unified platform means one programming interface, no compatibility headaches, and streamlined maintenance.
