Before connecting plastic pipe joints with gaskets, what should be done to the spigot end?

Beveling the spigot end of a plastic pipe joint is essential for ensuring a proper fit when connecting the pipes with gaskets. This process involves creating a slight angle on the edge of the spigot, which allows for easier insertion into the fitting and helps prevent damage to the gasket during installation. A beveled edge reduces the risk of tearing or pinching the gasket, ensuring a secure seal that can withstand pressure and reduce the chances of leaks.

This step is especially important in plumbing applications, where the integrity of the joint directly affects the performance and longevity of the piping system. Proper beveling aids in guiding the spigot into the fitting while promoting an even distribution of stress around the joint, enhancing overall durability.

Other methods, such as trimming the end or sanding the surface, while potentially useful in specific contexts, do not directly address the need for a proper connection that maintains the integrity of the gasket. Cleaning with solvent is crucial for preparing surfaces, but it doesn't directly impact the physical connection of the spigot end to the fitting as beveling does. Therefore, beveling is the most effective and appropriate method before joining plastic pipe joints with gaskets.
