How often should plastic piping be supported according to regulations?

  1. Every 2 feet

  2. Every 4 feet

  3. Every 6 feet

  4. Every 10 feet

The correct answer is: Every 4 feet

Plastic piping should be supported every 4 feet according to regulations. This requirement is in place to ensure the stability and safety of the piping system. Proper support prevents sagging and potential damage caused by stress and weight, which can lead to leaks or failure of the piping material. Additionally, providing adequate support helps maintain the integrity of connections and joints in the piping system, minimizing the risk of mechanical strain. The regulations recognize that while plastic piping is lightweight and more flexible than other materials, it still requires careful consideration to avoid deformation under its own weight or from external forces. Supporting plastic piping every 4 feet addresses these concerns effectively, ensuring that the installation adheres to safety standards and performs as intended.
