Record the actual arrangement
Start with the water source used at the property, if known. List any pump, pressure tank, water heater and treatment equipment separately. Use existing labels, manuals and installation records rather than assuming that neighbouring properties have the same arrangement.
A simple equipment list helps distinguish the system supplying water from devices heating or treating it.
Keep analysis and maintenance documents linked
For treatment enquiries, provide existing water-analysis results with their dates and the equipment details. Appearance, taste or staining can be described as observations, but should not be treated as a complete analysis.
Record previous maintenance or changes to equipment. If a document is missing, identify the gap instead of inferring which service was performed.
Use the record to frame the request
State whether the enquiry concerns water delivery, equipment operation, treatment selection or a planned renovation. Ask which system needs assessment and how proposed changes relate to the existing equipment.
The main Chelsea page covers local services; the Chelsea renovation guide covers project planning. This page is specifically an equipment-record checklist and does not prescribe a filter or confirm that the water is safe to drink.
