Connections should be permanently connected with_____ on drainage piping assemblies that uses PVC piping

Explanation:
Permanent joints in drainage PVC piping are made with the solvent cement specified for PVC. This cement, often used with a PVC primer, chemically softens the surfaces and fuses the pipe to the fitting, creating a strong, leak-free connection that is designed to be permanent. Tape isn’t suitable for PVC drainage joints because it can fail under pressure and won’t provide a true bond; solder is for metal piping; crimp fittings aren’t the standard method for typical PVC drain systems. Using the PVC-specific glue ensures compatibility and a proper, code-compliant seal.
