What is the purpose of the 25 lbs/psi pressure test?

The purpose of the 25 lbs/psi pressure test is to ensure the strength and integrity of the circulation system in a pool. This test involves pressurizing the system to a specified level, which typically is around 25 pounds per square inch (psi), and then monitoring it to verify that it can withstand this pressure without any failures. Successfully passing this test indicates that the circulation system's components, such as pipes, fittings, and connections, are robust enough to handle the operational pressures during regular use.

If the system fails the pressure test, it may suggest weaknesses or potential points of failure that could lead to leaks or other issues in the future. This test is a crucial step in the installation and maintenance of pool systems, as it helps prevent costly repairs and ensures proper functionality within the pool's plumbing system over time.
