This process involves filling the plumbing system of a residential structure with water and then pressurizing it to a specified level. The pressure is monitored for a set period to identify any leaks. For example, a plumbing system might be filled with water and pressurized to 5 PSI for 15 minutes. A drop in pressure during this time indicates a leak somewhere within the system.
Its implementation can prevent significant property damage caused by undetected leaks within water or sewer lines. Early identification of such issues allows for timely repairs, mitigating potential damage to flooring, walls, and foundations. Historically, this method has been employed in various industrial settings to assess the integrity of pipelines and pressure vessels, and its application to residential plumbing provides a proactive approach to home maintenance and leak detection.
