Treat a taste change as a reason to investigate

A salty taste does not identify the source or amount of dissolved substances. Do not repeatedly taste unknown water as a test. Record the change and ask a qualified laboratory or specialist which analyses fit your supply and intended use.

Check the history before equipment

Find out whether the supply source changed, a delivery was added, maintenance took place or the property was unused. Ask whether the change affects all outlets or one treated tap. These are useful observations, not proof of a cause.

Make the sampling question explicit

Explain that you are investigating a taste change. Ask whether conductivity, dissolved solids, chloride or other parameters are relevant. The laboratory should recommend a scope and specify bottles, sampling locations and transport requirements.

Compare like with like

Keep source-water and treated-water samples clearly labeled. Record date, time and any treatment operating at collection. A comparison only makes sense when the methods, units and sampling conditions are understood.

Questions for a treatment proposal

  • Which measured parameter does this equipment address?
  • What inlet conditions does it require?
  • What output will be checked after commissioning?
  • What are the waste-water, power and maintenance requirements?
  • Who responds if performance changes?

Avoid geographical shortcuts

Being near the coast does not prove the cause at a particular property. Bali Water Check does not publish household salinity estimates from an area name. Use local test evidence before committing to an explanation or installation.

Your next step

Record your observations in the water check. The testing guide helps you compare assessment scopes.

Questions worth asking

Does this guide assess water at my property?

No. It provides general context and a preparation checklist. A property-specific assessment needs appropriate inspection or testing.

What can I do without contacting a provider?

Create the free water checklist, print it and collect the records and questions described in this guide.
