Start with the observed problem
State which sinks, toilets or baths are affected, whether wastewater is backing up and where any outside overflow appears. Include neighbours’ observations only as reports, not a diagnosis. Stop using fixtures that worsen a backup and keep clear of contaminated water. Do not enter a chamber or lift an unsafe cover to identify the route yourself.
Separate clearance from investigation
Clearance aims to restore flow. Further inspection may help investigate a recurring fault or an inaccessible connection, but the proposed survey should answer a defined question. Ask which runs are accessible, whether clearance is needed first and how limits will be recorded. Restored flow and a confirmed defect are different findings; keep the distinction in any repair history.
What records can and cannot establish
Edinburgh Council provides a drainage-record search that can help locate recorded routes. Read the legend and treat a record as supporting information, not a guarantee that it reflects every later alteration. An inspection should describe what was actually seen or tested and what remains unknown. A camera recording alone does not settle which owners must pay.
Use Scottish guidance for responsibility
Do not assume that a pipe becomes a public responsibility simply because it serves another home. Shared-repair arrangements and the distinction between private drainage and the public network need checking for the actual property. Consult Scottish Water’s pipework information, the building records and appropriate advice. Do not import an England-and-Wales ownership rule into a Scottish enquiry.
Questions for owners, agents and factors
- Who can arrange access to the affected properties and known inspection points?
- What previous clearance, inspection or repair was completed, and when?
- What is the agreed purpose of the proposed attendance?
- What findings and limitations will be supplied, and who needs to receive them?
- Who can authorise further work after responsibility and scope have been checked?
Keep a factual handover
A useful note distinguishes observations, work completed, the inspected section and unresolved questions. Ask before booking whether photographs, recordings or written findings can be supplied and what they include. Do not assume a standard visit includes an insurance report or a legal opinion. For suspected public-network problems, ask Scottish Water to check the appropriate reporting route.
