What type of connections can a removable P-trap serve as for cleanouts?

A removable P-trap serves as a slip connection for cleanouts because it is designed to allow easy removal and cleaning of the trap without needing to cut or damage the plumbing. Slip connections are characterized by their ability to easily slide together and separate, which is ideal for maintaining plumbing systems, especially in areas where clogs may frequently occur.

In plumbing systems, slip connections are commonly used because they provide flexibility in installation and maintenance. They allow for adjustment in alignment and offer a tight seal when properly installed, minimizing the risk of leaks.

While ground joint connections and threaded connections are also used in plumbing, they do not provide the same level of convenience for cleaning that slip connections do. Ground joint connections require a more permanent fastening and are not typically designed for easy disassembly. Threaded connections, while secure, also require more effort to unscrew and reattach, making them less practical for routine access during maintenance tasks compared to slip connections.
