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.
