In a public swimming pool, what is the maximum water velocity allowed in copper discharge piping?

When considering the maximum water velocity allowed in copper discharge piping for public swimming pools, the standard is 8 feet per second. This limit is established to ensure that the piping system operates efficiently while minimizing the risk of erosion and damage to the pipes. Higher velocities can lead to increased friction, wear on the piping material, and the potential for pipe failures over time, which could compromise the integrity of the pool system. Additionally, maintaining a lower water velocity helps to reduce the noise generated by water flow and minimizes the chances of air entrainment, which can affect water quality and system performance. Therefore, setting the maximum velocity at 8 feet per second serves both operational safety and longevity of the piping infrastructure in a public swimming pool setting.
