When plumbing, you may find it confusing to choose the kind of pipes to install. Most of these pipes blend together.

Thus, you may be spoilt for choice. Right now, the answer is not clear like in the earlier years when galvanized pipes were the only choice. Here are the major types of pipes you can find today:


  1. PVC Pipes

PVC is an abbreviation for polyvinyl chloride.

Ideal usage: PVC pipes are best suited for vent and drain lines.

PVC pipes are widely used in plumbing. Their popularity is due to their lighter nature. They’re also easier to use in plumbing work than galvanized pipes. PVC pipes are mainly used for waste or drain pipes.

They can also be used for stacks. Stacks are the pipes that stick out of rooflines but don’t work as water supply pipes. It’s very easy and effortless to install PVC pipes. They merely require a miter box, hacksaw, and solvents for gluing the pipes together.

Diameters of PVC pipes are written on the whitish pipe surface. The diameter markings are often clear. If you’re unable to read the diameters, you can determine them using an appropriate sizing tool like a Pi-Piper.


  1. PEX
