  Flow Velocity in Plastic Piping Systems | Flow Control

  In plastic piping systems, Hayward defines a generally accepted safe flow velocity as no more than 8 feet per second for piping systems that do not have fast opening or closing valves. For systems that do have these types of valves such as solenoid valves or pneumatically actuated valves without speed controls the maximum velocity is usually 5 feet per second.
