What type of joint is often used for a permanent plumbing connection?

• A. Solder joint
• B. Threaded joint
• C. Compression joint
• D. Slip joint

Answer: (A)

A solder joint is often used for a permanent plumbing connection because it involves melting a filler metal, usually lead-free solder, to join two metal surfaces together. This process creates a strong and durable bond that can withstand the water pressure typically found in plumbing systems. Solder joints are particularly common in the connection of copper pipes, making them ideal for both residential and commercial plumbing applications. The permanence of solder joints is attributed to the nature of the soldering process itself, which, when executed correctly, results in a solid and leak-proof seal. In contrast, other types of joints, such as threaded, compression, and slip joints, may allow for disassembly and are often used in situations where a temporary or adjustable connection is necessary.
