"What is an expansion PVC coupling?"
If your PVC pipe develops a leak, the section of pipe with the leak can be cut out of the line and repaired with this coupling. The "hub" end of the expansion coupling
is glued onto one exposed end of the pipe; it’s then expanded by pulling on the telescoping end, and then attached to the other exposed end of the PVC pipe with a standard PVC coupling.
"How do I glue PVC fittings and valves to the pipe?"
Most PVC manufacturers recommend for the installer to follow the instructions for the cement and primer that is being used. Their instructions are usually found on the label of the container.
