WHY WATER TESTING MATTERS

Water can look clean and still cause problems.

Depending on where your water comes from, it may contain bacteria, minerals, metals or organic matter that affect:

Drinking water safety
Taste and odour
Staining on taps, showers and toilets
Scale build-up in hot water systems and appliances
Long-term performance of pumps and filtration systems

Testing tells you what’s actually in your water, so any Davey water solution you choose is properly matched to your home.

On Bore, Tank or Rural Water? Start With a Lab Test

If your household relies on bore, tank or rural water for drinking, cooking or showering, professional laboratory testing is the safest and most reliable way to understand your water quality.

Semtex makes the process easy. We send you a water testing kit with clear instructions and a pre-paid return courier. You collect the sample, send it to an independent New Zealand laboratory, and once the results are ready, we explain them to you, and let you know the next steps.

How the Semtex Water Testing Process Works

You start by telling us a little about your water. We send you a test kit with everything you need. You collect the sample, return it to the lab using the
pre-paid courier, and once testing is complete, we guide you through the results and the next steps.

From start to finish, the process is simple, supported and stress-free.

Why Test Your Water With Semtex?

Your water is analysed by an independent New Zealand laboratory using professional, validated methods. When the results are ready, we don’t just send you a report full of numbers; we explain what it all means in everyday terms.

If your water quality is acceptable and no treatment is needed, we’ll tell you. If improvements are required, we’ll outline practical, proven options using reliable Davey water solutions tailored to your home and water type.

The entire process is designed to make good decisions easy.

Ready to find out what’s really in your water?

Complete the enquiry form and tell us where your water comes from and how it’s used in your home. We’ll recommend the right test, guide you through the process, and help you move toward better water with confidence.

Choosing the Right Water Test

When you enquire, we ask a few simple questions about your water source and what you’ve noticed. From there, we recommend the test panel that makes then most sense for your situation, so you’re not paying for information you don’t need.

Some homeowners want a full safety check that includes both bacteria and
minerals, while others are focused on staining, hardness or taste. The goal is
always clarity and confidence.

Every water source behaves differently:

Bore water can vary dramatically from
one property to the next
Rainwater can pick up bacteria,
sediment and organic matter
Mains water may still contain
chlorine, metals or taste issues

That’s why testing is so important, especially before installing filtration, UV disinfection or whole-house water systems.
