What is a significant disadvantage of using rigid PVC conduits?

A significant disadvantage of using rigid PVC conduits is their susceptibility to damage from certain solvents. While PVC is known for its advantageous properties such as being lightweight, resistant to moisture, and having a long lifespan, it is not impervious to all chemicals. Certain solvents, particularly those that can dissolve or degrade plastic materials, can cause the PVC to weaken, crack, or fail entirely if they come into contact with it. This makes it crucial for installers and engineers to carefully consider the environment in which rigid PVC conduits will be used, particularly in areas where chemical exposure is likely. Understanding this limitation helps ensure the reliability and safety of electrical installations.
