Trace a connection with a specific question
Dye tracing uses a visible tracer to help investigate how water moves between drainage points. It may help test a suspected connection or identify where an accessible outlet discharges. Explain the start point and the destination you need to investigate, rather than assuming the exercise will produce a complete map.
Existing plans, chamber locations and previous findings help define the work. CCTV inspection answers different questions about pipe condition, and the two methods may be considered together where useful. A route observation does not by itself determine legal ownership or certify the condition of the entire system.
Observation points and records
Tell SouthFlow which outlets and chambers can be accessed and who can authorise work across the site. Discuss how findings will be recorded and what limitations should be explained. If measured mapping or another specified report is required, state that requirement before booking rather than assuming it is included.

Common questions
Can dye tracing replace a CCTV survey?
The two methods answer different questions. Dye tracing can help investigate flow routes, while CCTV can show the internal condition of accessible pipework.

Trace connections with a clear purpose
Dye tracing is most useful when the question is specific: which route does an outlet follow, where does a connection discharge, or are two drainage points connected? Share available plans and the locations that can be accessed.
Dye tracing investigates routes and connections. A camera inspection answers different questions about visible internal pipe condition; the methods may be considered together where appropriate.
Discuss the work before booking
Describe the issue
Provide the postcode, property type and relevant symptoms or findings.
Explain site access
Share the location of drainage points and any restrictions on working space or attendance.
Agree the scope
Confirm the proposed work, included costs and any required outputs or follow-up work.
Planning your drainage work
Will tracing produce a complete drainage plan?
Confirm the required outputs before booking. Establishing a connection does not automatically produce a measured plan or identify every part of the system.
What affects the cost?
The drainage condition, access, extent of work, preparation and attendance requirements affect the quote. Describe the job and ask which work and charges are included.
Do you cover the whole of Hampshire?
Yes. SouthFlow covers homes and businesses throughout Hampshire. See Hampshire coverage for locations served. The wider service area also includes Surrey and West Sussex.
Will dye tracing produce a measured drainage plan?
Not automatically. Demonstrating a connection is different from measuring and mapping the full network. Explain the output you need and agree whether the proposed scope can provide it.
Does dye tracing show cracks inside the pipe?
Dye tracing investigates routes and connections. A CCTV inspection is used to examine visible internal pipe condition; the appropriate combination depends on the question and available access.
