- :
5.1 Installation preparation
- .
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.
