Pressure and leakage testing

A controlled test of whether a section holds what is put into it.

What this page cannot establish

  • Pressure or leakage testing cannot establish the condition of sections outside the tested length
  • Pressure or leakage testing cannot establish the cause of any result
  • Pressure or leakage testing cannot establish compliance, unless the applicable authority says so

What it is for

To assess whether a defined, isolated section retains water or air under a controlled procedure.

When a professional may raise it

These are circumstances, not rules. No method is appropriate everywhere, and a professional declining to use one is not necessarily cutting a corner.

  • where a local process or an inspection requires it
  • on a newly installed or lined section, where a procedure applies
  • not applicable to every line or every situation

What to ask for afterwards

A method performed without a record produces very little you can carry into the next conversation.

  • the written procedure used and the section it covered
  • the recorded result

Practical constraints

  • requires the section to be isolated
  • not appropriate for every configuration
  • performed only by qualified professionals

Questions worth asking

  • Which section was tested, and how was it isolated?
  • What procedure was followed?
  • Is this test required here, or optional?

What would change the answer

  • the written procedure used and the section it covered
  • the recorded result

What to do next

Whether a test is required is a local question, and the answer determines whether it belongs in the price.
