Why is it important to use the correct fittings in plumbing?

Using the correct fittings in plumbing is vital primarily because it helps to prevent leaks and ensures the integrity of the entire plumbing system. Fittings are designed for specific applications and materials, and using the right type ensures a secure, tight connection that can withstand the pressure of water flowing through the system. Incorrect fittings can lead to various issues, including leaks that not only waste water but can also result in water damage, mold growth, and costly repairs. Adhering to the correct specifications for fittings reinforces the overall safety and reliability of the plumbing system, ensuring it functions as intended without compromising the performance or leading to potential hazards. This fundamental principle is essential for maintaining a durable and efficient plumbing infrastructure.
