Start with what you know

A cloudy appearance does not establish a cause or prove safety. Record the observation under normal conditions and ask an assessor how to investigate it. Do not rely on a home visual trick as a drinking-water clearance.

Make the record specific

If a guest sends a photo of a cloudy glass, retain the time and outlet name with the image. A photograph without that context may be impossible to compare with a later sample from another part of the system.

Your observation checklist

  • Record the outlet and when the haze was observed.
  • Note whether there was a recent supply interruption.
  • Ask whether untreated and treated outlets need separate sampling.
  • Keep your drinking-water question explicit in the testing brief.

The question to take to an assessment

Which inspection or analysis can distinguish the relevant possibilities at this outlet?

Keep the original observations, dates and documents together. If you commission a visit or test, agree its scope, costs and expected written output directly with the professional. Our online check does not book a technician or send your details to a provider.
