Start with what you know

A symptom you associate with water does not establish that water caused it. Persistent or concerning symptoms belong with a healthcare professional. A property assessor can investigate the water system without diagnosing your health.

Make the record specific

Instead of requesting a filter that promises to solve a skin complaint, keep two records: your healthcare questions and factual observations about the property supply. Avoid sending health histories through the property checklist.

Your observation checklist

  • Record visible water or equipment observations separately from symptoms.
  • Ask the host about the intended drinking supply.
  • Collect any existing water report without treating it as a medical finding.
  • Avoid buying a product on the basis of an unverified health promise.

The question to take to an assessment

What can the property assessment establish, and which questions should stay with my healthcare professional?

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.
