Describe what changed
Write down the symptom, the affected fixtures, and when you first noticed it. Let the team know about any previous work on the same issue.
Make access easier
Clear ordinary household belongings from the work area where practical, and let the team know about access restrictions.
Keep equipment details ready
A model number or manufacturer label can help prepare for a water heater or pump visit.
Review the proposed work
Ask what the quote includes, what may require a separate scope, and how the technician will explain additional findings.
