Which fitting type allows for easy disassembly of PVC pipes?

Mechanical fittings are designed specifically for easy disassembly and reassembly of PVC pipes. These fittings utilize a variety of mechanical components, such as clamps, screws, or bolts, which hold the pipes together without requiring permanent adhesive bonds. This feature allows for maintenance and adjustments to be made without damaging the pipes or fittings, which is particularly advantageous in applications where changes may be required.

In contrast, PVC cement fittings create a chemical bond between the pipes and fittings, resulting in a permanent connection that cannot be disassembled without cutting the pipe. Solder fittings are used primarily with metal pipes and involve melting solder to join the pieces, making them equally permanent. Compression fittings, while allowing some level of disassembly, are most commonly used with materials like copper or PEX rather than PVC, and may not provide the ease of disassembly that mechanical fittings offer for PVC applications.
