Can a clogged trap cause a leak?

PVC pipes under sinks include the P-trap that connects the drain to the house plumbing. Such pipes can be connected using threaded pieces or with glue. Gluing your PVC pipes creates a much stronger and permanent hold that can only be broken by cutting off the pipes.

How tight should sink plumbing?

Can you glue PVC twice?
In fact, you can, as long as you accept that it will not provide a bond as strong as “cold welding” with PVC cement. As answered before, PVC cement is not a glue but a solvent, melting the PVC so you can “cold weld” it without using heat.
How do you keep PVC pipes together?
Joining a pipe to a pipe fitting requires specially formulated primer and cement—no ordinary adhesive but a chemical solvent that melts the surface of the PVC and then quickly re-hardens to fuse the pieces together. The result is an airtight, leak-proof bond similar to what you get with welding metal.
