The Puretec NTS4000 Neutralising System is a high-capacity whole-house solution designed to correct acidic water and protect your plumbing, fixtures, and appliances from corrosion. Ideal for larger homes with 2+ bathrooms, the NTS4000 delivers reliable, consistent performance across multiple outlets without compromising water pressure.
Acidic water (typically below pH 7) can gradually corrode pipes, fittings, and seals, leading to costly damage and visible issues such as blue-green staining on sinks, taps, and showers. The NTS4000 combats this by utilising a high-grade calcium carbonate media, which slowly dissolves into the water to safely raise the pH to a neutral level.
With its high flow capacity (up to 90 LPM) and durable upflow design, the NTS4000 ensures effective treatment even in demanding household applications. Its simple, non-electric operation makes it both energy-efficient and low maintenance, while the integrated media refill port allows for easy servicing when required.

How It Works:
As water passes through the system, it flows through a bed of neutralising media. This media gradually dissolves, increasing the pH level of the water while forming a protective barrier against corrosion throughout your plumbing system.
The Puretec NTS4000 is the ideal solution for households experiencing acidic water issues and looking for a dependable, long-term water treatment system.
