Hi this just means to check if the system has any further leaks.

Soundness Test

  • BS 6700 - requirements for testing copper/plastic pipework
  • Testing non-plastic pipes
    • the installation shall be pumped up to 1.5 times the normal working pressure
    • the test shell be for 1 hour
    • during this there should be no visible leaks and no loss of pressure
  • Testing systems containing plastic pipes
    • Test A
      • Pumping for 30 minutes and pressure is noted
      • the pressure is reduced to one third of the test pressure
      • the pressure does not drop over the following 90 minutes
      • there is no visible leaks through out the test
    • Test B
      • Pumping for 30 minutes and pressure is noted
      • the drop in pressure is less than 0.6 Bar (60kPa) after a further 30 minutes
      • and less than 0.2 Bar after the next 120 minutes
