What is the purpose of using washers in plumbing connections?

The primary purpose of using washers in plumbing connections is to prevent leaks. Washers create a seal between two surfaces, such as between a nut and a pipe, or between two fittings. This sealing action is crucial in plumbing systems, where maintaining a tight, leak-free connection is essential to prevent water loss and ensure the system functions effectively. The materials from which washers are made, such as rubber or silicone, provide flexibility and durability, adapting to the surfaces they contact and filling any small gaps that might otherwise allow water to escape.

Using washers helps to absorb vibrations and accommodate slight misalignments in fittings, further enhancing the integrity of the connection. Properly installed washers can significantly reduce the risk of leaks in fixtures, taps, and piping, which is vital for safeguarding against water damage and maintaining the efficiency of the plumbing system.
