Which is a common type of pipe joint used in plumbing?

A solvent weld joint is a prevalent type of pipe joint in plumbing applications, particularly when working with PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride) pipes. This joint is created by using a solvent cement that softens the material on the surfaces being joined. When the two pieces are pressed together, they fuse to form a strong, permanent bond as the solvent evaporates.

Solvent weld joints are highly favored due to their ability to create a watertight seal that can withstand various pressures and conditions in plumbing systems. This makes them ideal for drainage, waste, and vent systems. Additionally, the seamless nature of a solvent weld joint minimizes the risk of leaks, contributes to the flow efficiency within the pipes, and is relatively easy to apply with proper technique and adherence to safety guidelines.

Other types of joints, such as screw joints, compression joints, and flanged joints, do serve important roles in plumbing but are typically used in different contexts. For example, compression joints are frequently utilized in situations requiring disassembly or adjustments, whereas flanged joints are employed in larger pipe configurations where a strong seal and the ability to remove the joint for maintenance is necessary.
