Onsite Testing

Price: $36-$41 (plus any additional chemicals) for the Tauranga area. An additional mileage charge may apply for locations outside Tauranga.

Shop Water Testing (Free of Charge) You can also bring a water sample to our shop for testing free of charge providing you are getting your chemicals from us.

Our onsite testing service includes:

  • Testing and balancing your pool water.
  • Clearing skimmer and pump baskets.
  • Backwashing the filter.
  • Checking over the entire pool system.

We’ll leave a detailed pool service report on-site, showing the water test results and any recommendations we have for keeping your pool in top condition. You can choose to use your own chemicals, or we can provide high-quality products to get the job done.

Shop Water Testing Guidelines

If you prefer to bring a water sample to our shop for testing, please make sure to:

  • Use a clean container (not metal) to collect the sample.
  • Take the sample from at least 400mm below the water surface to ensure an accurate representation of your pool's water quality.
