Types of Plumbing Pipes

The type of pipes you choose for your project depends on its purpose. Will it be for water supply, drain-waste-vent or a gas line? There is no shortage of choices when it comes to plumbing pipes and it only begins with plastic vs. metal. PEX pipes vs. copper? How about CPVC vs. PEX?

One thing in common with all types of pipes is they need to be replaced as quickly as possible when they develop a leak or break. This guide will teach you about the types of pipes for plumbing. You&#;ll learn more about some common types of pipes for water supply, natural gas and drainage use and how to measure pipes properly.

Tip: Before replacing or installing new pipes for water or gas, always consult local building codes and regulations. Some areas of the country require installation by a professional, while others dictate the types of pipes required for certain applications. Permits are not usually necessary for repair or replacement work, but they are required if you are running pipe in a new location. Always use extreme caution when working with gas lines.

PEX pipes differ from traditional rigid pipes in one obvious way: They&#;re flexible. This makes it easier to snake them to different areas of a home. Using PEX piping may require running more pipe, but it also involves fewer fittings. PEX crimp tools offer a simple way to make these flexible fittings more secure and watertight.

Here are a few other advantages of PEX:

  • It&#;s quieter than rigid piping.

  • It has a smooth interior that resists scale buildup and corrosion, which can affect pipe flow over time.
  • It&#;s freeze-break resistant, although not freeze-proof. PEX tools, such as specialty expansion kits, will enhance this benefit by absorbing dimensional changes caused by thermal expansions/contractions.
  • PEX systems have appealing installation costs compared to rigid materials.
  • PEX piping is often used in green buildings, installed either as a remote manifold or plumbing system.

PEX pipe and crimp fittings, with all their benefits, do have a drawback: Because UV exposure causes a reaction with polyethylene, it isn&#;t suitable for outdoor use. The maximum level of UV exposure is typically no more than 60 days, but this varies by manufacturer. Using PEX for underground water supplies isn&#;t ideal, even if UV exposure is decreased.
