PVC Pipe is a versatile form of pipe which has revolutionized modern plumbing. PVC can be used for drainage, waste water or vent piping but is not suitable for water supply, in which case, copper pipe is most commonly used.

PVC stands for Polyvinyl Chloride which is a compound designed for strength and durability. It is resistant to corrosive materials found in cleaners and other household chemicals and also to the extremes of hard and soft water. It resists leakage and does not conduct electricity. For these reasons it is the common choice for modern plumbing and for replacing old plumbing.

There are many different sizes, lengths and diameters of PVC pope available. Pipes are designed to fit within each other and fixed with solvent cement. PVC pipes are measured by their inside diameter.

A coupling is the term used to describe a join between two pieces of PVC pipe, in particular when they are joined with no angle. Joins can be of varying degrees however, typically they are 22, 45, 60 and 90 degrees. An angled join is generally called an elbow.

Transition pieces are available to allow connection with other types of piping. A threaded adapter is available which will allow joining between threaded galvanized pipe. For connecting to non threaded metal pipe a gasket can be used which threads over both ends of pipe and is then secured in place using stainless steel clamps.
