  • :

5.1 Installation preparation

  1. .

5.2 jointing of (PP-R) pipes and fittings :

  • Testing
  • Backfill along the pipe except above the pipe joints and fitting untill we proceed with the pipe test.
  • Test of the pipe according to the project specification section 02510 Division 3.5
  • Subject systems to water pressure test to prove tigtness and to flow test to prove freedom from obstruction.
  • Close all opening with plugs and fill system to point of overflow at highest opening.
  • Vent all air and ensure that water reaches all parts of system to be tested.
  •  All close sections to be tested Hydrostatic pressure Test at least 15 minutes .
  • Inspect all joints and pipes whilst under pressure and correct leaks or detective joints by replacing with new joints and materials .
  • Use callibrate pressure gage for test to prove test pressure and continue use it at all test time.
  • Repeat test after corrections are made and until systems are proven tight. 
  • Welding Device and tools .
  • Plumber tool box.
  • Personal tools.
