Dye Testing for Fault Finding & Flow Identification
Dye testing is an effective way to investigate drainage flow paths, identify incorrect connections, locate leaks, and trace drainage issues within complex systems.
By introducing non-toxic coloured dye into drainage systems, we can monitor water movement and accurately determine where systems connect or where issues may be occurring.
Dye testing can help identify:
• Misconnected drainage systems
• Unknown drainage routes
• Surface water and foul water cross connections
• Leaks and defective pipework
• Flow restrictions and drainage failures
• Drainage ownership and responsibility
