How long should a hydronic system be hydrostatically tested?

In the context of testing a hydronic system, a hydrostatic test is crucial for ensuring the integrity of the system and checking for leaks. The standard duration for a hydrostatic test is typically set at 2 hours. This timeframe is deemed sufficient to allow for a thorough examination of the entire system under pressure. It provides enough time for any potential issues to become apparent, such as leaks or weaknesses in the piping or connections, which might not be detectable in a shorter test period.

A 2-hour test strikes a balance between efficiency and thoroughness, ensuring that the system can be safely pressurized without leading to excessive downtime. During this testing period, technicians can monitor pressure readings accurately and visually inspect joints and fittings. This practice aligns with safety standards and recommended protocols in the industry, providing a reliable method for confirming the system's readiness for operation.
