How long is a hydrostatic pressure test typically conducted?

A hydrostatic pressure test is typically conducted for a duration of 24 hours to ensure that the system being tested can withstand the expected pressures without any leaks or failures. This extended testing period allows for a thorough assessment of the integrity of pipelines, pressure vessels, or storage tanks. It is important to monitor the pressure throughout the entire duration to detect any gradual loss of pressure that could indicate a leak.

Conducting the test for a shorter period, such as 1 or 2 hours, may not provide sufficient data to confirm the reliability and safety of the system under long-term operational conditions. A 12-hour test could also be considered insufficient because it might not adequately capture slow leaks or system weaknesses that emerge over a full day. By extending the test to 24 hours, operators can collect more comprehensive insights into the performance and durability of the water treatment infrastructure.
