What is the maximum water velocity in copper discharge piping of a public spa?

The maximum water velocity in copper discharge piping of a public spa is recognized to be set at 2 feet per second. This is primarily due to the physical characteristics of copper piping and the potential issues that can arise from higher velocities, such as erosion, noise, and vibration.

Keeping the water velocity within this limit ensures that the infrastructure remains intact and operates efficiently over time, minimizing maintenance and repair costs. Lower water velocities in copper piping also help reduce the likelihood of turbulence, which can lead to the formation of air pockets and potential problems with water circulation and heating in spa systems.

Establishing a maximum velocity helps ensure compliance with safety standards and promotes the longevity and reliability of the plumbing infrastructure within the public spa.
