Different Types of Piping for Plumbing in Your Home

The majority of homes in the U.S. were built before 1970, meaning most have galvanized steel or copper pipes. Newer homes typically have plastic pipes or PVC. Types of residential piping include: 

Galvanized Steel

Galvanized pipes have a protective coating of zinc applied to protect against corrosion. However, they can still corrode over time. Most will provide reliable operation for around 40 years.


Copper pipes are rigid and resist corrosion, making them ideal for buried water service lines. With a high pH level of the water, these pipes can corrode, as can large quantities of dissolved oxygen and salts.

Polyvinyl Chloride 

Gray or white PVC pipes are among the most common pipes used in homes and irrigation systems today. PVC pipes also have “schedules,” which refer to their thickness. Schedule 40 pipes, the most common, can deliver cold water. Schedule 80 pipes (often the dark gray ones) have thicker walls and can deal with higher pressures.

Chlorinated Polyvinyl Chloride 

CPVC pipes, like PVC, are also plastic pipes used both above and below grade. They withstand higher temperatures and greater pressures than standard PVC. 

Cross-Linked Polyethylene 

PEX, like PVC and CPVC, is another type of plastic water supply line for both above and underground applications, but they can deteriorate when exposed to UV radiation.

Choosing the Right Pipe

Are your pipes suited to meet your needs? Pipes have various ratings for pressure and temperature, or “P-T Rating.” Find out which types of pipes are best for specific applications below!


Copper, PVC, CPVC, and PEX can deliver drinking water. 

Non-Potable Water

All types of pipes can carry and supply non-potable water into your home. However, there are strict regulations for labeling pipes, especially plastic ones.

Hot Water

PVC is the only pipe that you may not be able to use for hot water unless otherwise rated, such as the schedule 80 variants.

CPVC pipes are typically rated for hot water applications.

White and gray PEX pipes are also often safe for use in hot water applications.

Home Systems That Rely On Each Pipe Type And Drain

PVC Pipes

Drain lines carry used water and waste from your home to the main drain, where it flows to the on-site septic tank or municipal sewer line. The main drain then connects to either an on-site septic tank or the municipal sewer line. 

CPVC Pipes

CPVC can replace copper pipes. It’s also the typical go-to for applications where you want to use PVC but can’t use it.

The Common Types Of Pipes

Metal, PVC, or CPVC pipes often make up a bulk of a home’s plumbing system. There are several other types of pipes, such as stainless steel, cast iron, and brass, which may also be in your home. In addition, you may find acrylonitrile butadiene styrene piping.

Troubleshooting for Leaks

The easiest way to troubleshoot your water lines for leaks is to monitor your water meter. Shut off all faucets, fixtures, and water-using appliances. At this point, the water meter should no longer move. In an older analog meter, you can see this right away if the gauge uses a pin. If you have a digital meter, you may have to wait for about an hour to see if there’s a change in the reading. If the pin moves or you see the numbers change, it likely means you have a leak. Other signs can include discolored or foul-smelling water.

How To Keep Your Water Lines Clean

A water treatment system that incorporates the following can keep your water lines clean:

  • Water softeners
  • Filtration units
  • Distillation systems
  • Reverse osmosis
  • Ultraviolet sterilization

What Our Clients Are Saying
testimonial_image The tech was at my home less than 10 minutes and gone within 20 minutes due to having my A/C up and running. I really appreciate his response to my home and working with my son due to me being out of town, but we spoke on the phone.
