Water Line Pressure Testing

• The necessary pump, hoses and tools to perform the high pressure test.
• Experienced, insured personnel in water line testing procedures.
• Certified test results for the owner, contractor and engineer.

• Pressure testing ensures the integrity of newly installed or repaired water lines, valves and hydrants.
• Testing is usually done to AWWA Specifications at 11⁄2 times the operating pressures unless otherwise specified by the engineer. This ensures the system will stay intact when experiencing water hammer.
• Saves the utility or contractor from having to purchase special equipment.
• A time saving method of testing for the contractor.
• Meets or exceeds engineers' requirements for system acceptance.
  
  

Caution: Extremely high internal pressures are generated when hydrostatic pressure testing takes place. Careful attention must be given to caps and plugs to prevent blow-off.

• The pipeline must be full of water and have the air purged from the system.
• Provide an additional source of water to be used to pressurize the system.
• Provide a 3⁄4" pump connection at the main.
• The system must be isolated with all fittings, valves, hydrants, caps and plugs restrained.

• Size of the pipeline being tested.
• Length of pipeline to be tested.
• Are there valves in-line for isolation?
• Are there any services installed off the pipeline?
