Description
Homes that rely on tank or bore water often deal with low pH levels, and that acidity slowly eats away at pipes, fittings, and even your filters. The PureZone Calcite pH Neutralising System tackles that by lifting the pH naturally using crushed calcite stone. The setup runs without chemicals or electricity, relying on simple water contact to correct acidity as it flows through. Once installed, it quietly protects your plumbing, fixtures, and water quality across the whole house.

Key Features
This system is made for households that need a straightforward, natural fix for acidic water.
-
Raises pH through a mineral process, not chemicals or additives.
-
Helps prevent corrosion in copper pipes and fittings.
-
Adds small amounts of calcium and magnesium, improving taste.
-
Works with most whole-house filter or UV setups.
-
Refill design makes topping up calcite simple, no dismantling required.
-
Available in several sizes to match your household flow rate.
How It Works
Inside the tank sits a bed of calcite media. As acidic water passes through, a light reaction occurs that slowly dissolves the calcite and brings the pH up towards neutral. Because the media breaks down over time, it needs refilling every few months or once a year depending on how much water you use. It’s a quiet process that keeps your water gentle on plumbing and safe to drink without changing the feel or pressure.
Where to Use It
This setup fits best on tank, bore, or rural supplies that test below pH 7. It also works well as a front-end treatment before carbon filters or UV sterilisation, giving those systems a better starting point to do their job. Many rural homes around New Zealand use these systems to protect copper lines, fittings, and hot water cylinders from slow corrosion.
Pro Tip
Check your pH a few times a year, especially after heavy rainfall or seasonal changes. When the reading starts to drop, it’s time to top up the calcite. Keep a small bucket of media on hand so you’re not caught short.
FAQs
1. How do I know if I need a pH neutralising system?
If your water leaves blue-green stains on fittings or tastes slightly metallic, it’s usually a sign the pH is too low. You can confirm it with a simple pH test kit or lab test. Anything under pH 7 means your water is acidic and may need treatment.
2. How often do I need to top up the calcite?
That depends on how much water your household uses and how acidic it is. Most homes top up the calcite every six to twelve months. When flow starts to slow or pH readings drop, it’s time for a refill.
3. Can I use this with my UV or carbon filter setup?
Yes. It’s best installed before your main filtration or UV unit so the water is already balanced when it reaches those systems. This helps everything downstream run longer and cleaner.
4. Does the system change the taste of the water?
You might notice a slightly fresher, cleaner taste because of the small increase in calcium and magnesium. It won’t make the water chalky or leave residue if maintained correctly.
5. Can I install it myself or do I need a plumber?
If you’re comfortable working with standard water fittings, you can set it up yourself. It connects much like a whole-house filter. If you’re unsure about pressure or plumbing layout, it’s safer to have a local plumber handle the install.
