You have several types of plumbing pipe materials to choose from these days. The four that rank highest on the long list of options include PEX and copper for water supply lines, and PVC and ABS for drain, waste, and vent pipes. Weigh the pros and cons of each option to help you decide what pipe to use in your home.
PEX Plumbing Pipes
Cross-linked polyethylene, or PEX, is a popular material for water supply lines in new homes. It can also be installed in retrofit projects. PEX is a flexible plastic pipe able to weave through a home with minimal connective joints required.
Pros of PEX Pipes
- Fast and easy to install
- Virtually leak-free
- Color-coded to organize hot and cold water lines
- Withstands high pressures and temperatures
- Compatible with copper pipes
Cons of PEX Pipes
- Untested in the long-term due to its relative newness
- Can’t be used outdoors
- Not recyclable
- Not recommended for all uses or approved in all areas
Copper Plumbing Pipes
Copper has been a standard water supply line material since the 1960s and remains a popular choice to this day. This is due to copper’s many great qualities, though it also has some drawbacks to consider.
Pros of Copper Pipes
- Corrosion-resistant
- Suitable for high-pressure hot and cold water supply lines
- Durable and long-lasting
- Supports good drinking water quality
- Recyclable
Cons of Copper Pipes
- Expensive
- Heavier and more difficult to install
- Requires soldering and additional fittings during installation
PVC Plumbing Pipes
Polyvinyl chloride (PVC) is a rigid plastic used for drain, waste, and vent pipes. It was originally introduced as a lighter, easier-to-work-with material than traditional galvanized steel.
Pros of PVC Pipes
- Inexpensive
- Rust-proof
- Relatively easy to install
Cons of PVC Pipes
- Impossible to disconnect glued pipes without cutting them
- Prone to leaking if not installed correctly
- Not rated for high-pressure or hot water transport
- Not legal in all areas
ABS Plumbing Pipes
Acrylonitrile butadiene styrene (ABS) looks similar to PVC and is also used for drain, waste, and vent pipes. However, ABS is black and slightly less rigid than PVC.
Pros of ABS Pipes
- More durable than PVC
- Good for underground exterior use
- Withstands cold temperatures and high pressures
Cons of ABS Pipes
- Degrades in sunlight
- May be louder than other drain pipes
- Not legal in all areas
