Clear stop signs

Multiple affected fixtures, rising wastewater, strong sewage odour, leaking joints, solid resistance and a fast recurrence all point beyond a simple product choice.

  • Water rises at the lowest outlet
  • A tool cannot be retrieved easily
  • A chemical remains in standing water
  • The pipe or fixture moves or leaks
02

Make the handover useful

Record the symptoms, affected fixtures, access points, tools and chemicals already used. This helps the engineer plan the attendance and work safely.

  • Product name and dose
  • Time the symptom began
  • Previous repairs or surveys
  • Photos from a safe position
