Which type of pipe joint allows flexible alignment, is inexpensive to manufacture, and easy to assemble?

The push-on joint is particularly advantageous because it is designed to accommodate slight misalignments between pipes, thus providing flexibility during installation. This feature is especially beneficial in situations where precise alignment might be challenging due to ground shifting or other environmental factors.

Additionally, the manufacturing process for push-on joints is usually less complex than some other types of joints, making them less expensive to produce. This cost-effectiveness, combined with ease of assembly—often requiring no special tools or adhesives—makes push-on joints a popular choice in various plumbing and water treatment applications.

In contrast, other types of joints, such as socket, cement, and threaded joints, can involve more stringent requirements for alignment and assembly, potentially increasing both time and cost during installation.
