Start with what you know

Discoloration deserves a clear record. Color is not a laboratory identification: do not label a substance as rust, iron or sediment solely from a photograph. Avoid treating visibly changed water as confirmed drinking water.

Make the record specific

If the issue began after plumbing work, record the work date and the fixtures involved. Send the assessor an ordinary-light photograph and the chronology rather than buying equipment described as a universal color solution.

Your observation checklist

  • Record whether the change is continuous or intermittent.
  • Identify which outlets are affected.
  • Keep recent plumbing, delivery and tank-service details.
  • Ask the laboratory whether samples before and after treatment are useful.

The question to take to an assessment

Which inspection and measurements would identify the relevant cause before treatment is selected?

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.

Does the online check include a test or visit?

No. It creates a free preparation checklist. External tests, visits and equipment require a separate agreement with the professional you choose.
