When is it recommended to perform an air test at 25 PSI before introducing water into the system?

Performing an air test at 25 PSI before introducing water into a system is particularly recommended when water damage is a concern because this testing method helps identify any leaks or weaknesses in the system that could lead to unintended water release. By conducting an air test, you can ensure the integrity of the components before they are subjected to the pressures and forces associated with water flow. This proactive approach is crucial in minimizing the risk of water damage, which can occur if leaks are present and left undetected prior to filling the system with water.

If water damage is a key concern, it highlights the importance of checking for well-sealed joints and fittings, ensuring that there are no gaps that could allow water to escape once the system is operational. Addressing potential issues during the air test phase allows for repairs or adjustments to be made before water is introduced, thereby ensuring a more reliable and safer system operation.
