Types of Plumbing Pipes: Which Pipes are Best for Your Home?

Millions of Texans have recently had to deal with power outages and frozen and burst water pipes due to the extreme weather experienced in February. No doubt we all shared some inconvenience as we faced this bout of unusually icy weather. But why were pipes freezing? One of the main reasons for the frozen and burst pipes is that we don’t typically get freezing temperatures in this part of the country. Because of this, our homes and the placement of our water pipes don’t take extreme cold into account. In other parts of the country, walls are built thicker, homes have more insulation, and pipes may be several feet underground or run up through a basement. In Texas, our pipes are fitted to exterior walls or in attics; because of this, they are not insulated and can therefore freeze quickly.

The Most Common Home Plumbing Pipe Types:

PEX Pipe

Are you looking for the latest and greatest in piping? One of the newest pipes in plumbing is PEX pipe, or cross-linked polyethylene, and it is gaining popularity quickly. But it is used only to supply water. Rigid enough to withstand water supply pressure and flexible enough to weave through walls, ceiling, basements, this piping is a top choice for water-supply plumbing. 


  • Easy to understand color-codes: red for hot water, blue for cold 
  • Super flexible; even 90-degree curves are possible
  • Push-fit plumbing fittings will work to attach, among others
  • Inexpensive
  • Will join with copper piping
  • Easy to cut


  • Since its new, long-term capabilities are untested
  • May leak with push-fit plumbing fittings
  • Not recyclable

PVC Pipe

For drain or vent line plumbing pipe, PVC, or polyvinyl chloride, is your go-to pipe. PVC has been around for a while now as an alternative to traditional galvanized steel pipes. It became popular because it is light and easy to work with and install. So easy; in fact, you will only need a hacksaw and a miter box to cut. Another bonus, PVC glues together with solvents.


  • It comes with clearly marked diameters on the surface of the pipe
  • Inexpensive and a good choice for long runs like irrigation
  • Easier to work with than steel or copper


  • It cannot be unjoined and must be cut
  • If not installed properly, glued pipes can be prone to leaking 
  • Degrades in sunlight

Rigid Copper Pipe

Most often used for water supply lines within the home, rigid copper is easily cut with a hacksaw or a special copper tube cutter. And, these pipes are great for the water supply because they do not come with any health risks. There are many options for connections for rigid copper piping, the best being the solder-type connection. But note that this requires experience and safety protocols.


  • Can handle heat and intense pressure well
  • Easy to recycle and has a monetary value


  • You need experience to work copper piping due to soldered connections
  • It is expensive

ABS Pipe

ABS (acrylonitrile butadiene styrene) pipe is mainly used as a vent and drain line. Although it looks very similar to PVC piping, it is black and slightly softer. It is also made with BPA, which is a chemical commonly used to harden plastic. Although BPA has recently received a bad reputation, its current assessment from the Food and Drug Administration states that it is safe. ABS piping has a one-step process for connecting pipes; they can be bonded instantly with a block of special cement, and there is no need for a primer as with PVC piping. 


  • Stronger than PVC pipes
  • Suitable for underground exterior use
  • Works well in cold temperatures


  • Often not permitted by building code
  • Warps and deforms at certain temperatures

Flexible Type Connection

Flexible connections, or commonly called Flexi’s, are used for final connections to appliances. Like water heaters, toilets, sinks, etc. They are not allowed to be used inside walls and floors, so ensure you follow local codes when using Flexi’s. They are used on gas and domestic water and come in many lengths and sizes. 


  • Will fit in a tight and even unusually shaped area
  • Excellent tolerance for high heat 


  • It is expensive
  • Thin and prone to breaking

Galvanized Steel Pipe and Cast Iron

The two types of pipe commonly found in older homes and infrequently installed these days are steel and cast iron piping. These were used for many years before their plastic alternatives became popular. 

  • Galvanized steel pipe: This piping was used for drainage, water supply, gas supply, and any number of other purposes. Although it is still around, particularly for gas supply, it is far less used nowadays and is not used for water supply in new projects. Each end of the pipe is threaded, and individual pipes are screwed into each other with connecting fittings.
  • Cast iron pipe: This piping has been used for sewer and other drainage purposes for many years. Cast iron is weighty and difficult to cut and is still found in many homes, and it is viable until the point that it rusts entirely through. Once the time comes to replace it, you will find it most often replaced with rigid plastic pipes such as ABS.


  • Galvanized pipes are not used for plumbing anymore. However, they are still required for use with natural gas.


  • Galvanized steel pipe eventually corrodes and blocks water flow.
  • Some galvanized steel pipes may pass lead into the water supply.
