Weak water pressure or a ceiling stain can signal a pipe problem. When that happens, you’ll quickly see how much the material behind your walls matters. Some pipes corrode, some crack, and others fail when used in the wrong place.
As experienced plumbers in Richmond, VA, Leak Finders works with these materials in local homes every day. In this guide, we explain the different types of pipes used in plumbing, starting with what they’re actually made from.
Plumbing pipes are generally made from either plastic or metal. Each material serves a specific purpose based on water temperature and code requirements.
Some pipes serve supply lines, while others support drainage and venting. A material that works well for drains may not work for hot water. This is why pipe selection should match the line’s purpose.
Pipes are not all designed for the same purpose. The sections below compare the different types of pipes used in plumbing systems:
Several types of plastic pipe are used in residential plumbing systems. The examples below show where each type is usually used:
Many older homes still include metal piping. These materials have clear strengths and failure points:
Many homes do not use one pipe material from start to finish. Additions, remodels, and past repairs can leave multiple pipe types in a single system. A newer bathroom may have PEX, while older areas may still rely on copper or galvanized lines. This mix can affect how a plumber plans repairs.
Connecting different materials may require specific fittings to reduce the risk of leaks and corrosion. Local code also affects which materials are allowed for each line. Before replacing a section, a plumber should review the existing layout and choose a compatible repair. This step helps prevent poor connections between pipe materials.
If you’re replacing pipes, the best material depends on your home’s age, budget, and plumbing needs. PEX is a popular choice for water supply lines because it is flexible, affordable, and resistant to freezing. Copper remains a durable option for long-term reliability, while PVC is commonly used for drain and vent lines.
A plumber can evaluate your existing system and recommend materials that meet local code requirements and work well with the rest of your plumbing.
