Put the property first
Gather the water source, tank and pump details, existing treatment, service history and any reports. A specialist can make better use of a specific property brief than a general filter request.
Tell us what matters
Are you dealing with recurring marks, an unusual change, drinking-water uncertainty or maintenance? Explain the desired outcome and timing. Your answers create a preparation checklist; no provider receives your details.
Keep your options open
Ask for written recommendations, scope, installation requirements and ongoing maintenance. Agree costs directly with the provider before work.
Start with a practical checklist
Read the villa water guide, use the due-diligence checklist, or check your water.
