At what pressure should waterlines be tested?

The standard pressure for testing waterlines is typically set at 700 kPa. This pressure is used to ensure that the system can handle typical operating conditions while also identifying any potential leaks or weaknesses in the installation. Testing at this pressure helps verify the integrity of the system, ensuring that it can safely hold water under pressure without any failures. By adhering to this standard, plumbers can ensure that the plumbing installations are reliable and meet safety requirements before being put into operation.
