Start with what you know

An odor description alone cannot identify what is in the water. Write down a smell already noticed without deliberately inhaling or tasting unknown water. Keep the observation specific: when, where and under which ordinary use conditions.

Make the record specific

A report confined to one bathroom needs a different inspection brief from a change at every cold-water tap. Tell the assessor whether the observation concerns water, a drain or the surrounding room, if that distinction is already clear.

Your observation checklist

  • Record hot-water and cold-water observations separately.
  • List the outlets affected during ordinary use.
  • Collect tank, heater and filter service dates.
  • Note recent vacancy, maintenance or supply changes.

The question to take to an assessment

Should the inspection begin at the outlet, heater, tank or source, and what evidence will guide that decision?

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.

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