| PVC Pipe | |
| Polyvinyl Chloride (PVC) is a white pipe material made from the same material as vinyl windows. It can be used for water supply lines, fittings and waste and drainage lines. | |
In fittings it is threaded and usually intended to be install by hand-tightening. In water supply lines and waste lines it is joined with fittings and a special solvent.

Example of a defective PVC fitting installation (and a missing vent).
