The pipes in your home play a key role in keeping your plumbing system reliable. Supply pipes bring fresh water to sinks, showers, and appliances. Drain pipes carry used water and waste away. Each type of pipe material has its own strengths and limitations.
Knowing what kind of plumbing pipes you have, how they perform, and when replacement is needed can help prevent costly problems. Below, we outline the most common pipe materials, their benefits, and which options work best for modern homes.
Supply Pipes: What Carries Water in Your Home
Water supply pipes bring fresh water to your sinks, showers, and appliances. These pipes need to be strong, clean, and dependable.
Copper Pipes: A Trusted Standard
Copper is still the top choice for many pros.
- Long-lasting (over 50 years)
- Doesn’t rust or clog
- More costly to install
- Requires skilled labor
If you’re looking for a long-lasting system, we still suggest copper, even if it’s pricier at the start.
PEX Pipes: Modern and Flexible
PEX is a plastic pipe that has become very popular. It’s flexible, easy to install, and cheaper than copper.
- Comes in PEX-A and PEX-B types.
- PEX-A has better flow (full size inside).
- Can freeze and thaw without bursting.
- Ideal for pipes near exterior walls.
We install PEX often because it works well in many homes and helps save on labor and material costs.
Galvanized Steel: Old and Problem-Prone
If your home has galvanized water pipes, it’s time for an update.
- Common in homes built before the 1960s.
- Rust builds up inside over time.
- Can reduce water pressure.
- May cause rusty water.
Key Takeaway: Galvanized pipes are like clogged arteries. If you still have them, replacing them with PEX or copper can prevent water flow issues and damage.
Polybutylene Pipes: The One to Avoid
This old gray plastic pipe was used in homes during the 1970s through the 1990s. It is known to fail without warning.
- Cracks under pressure
- Breaks down from chemicals in water
- Not used anymore in new homes
If your home still has polybutylene, replacement is a must.

Drain Pipes: What Carries Wastewater Out
Drain pipes remove used water and waste from your house. They don’t carry pressure, but they still need to be strong and leak-free.
Cast Iron Drain Lines
These were the go-to for many years in older homes.
- Strong and long-lasting
- Very heavy and hard to work with
- Can develop cracks over time
If your cast iron drain pipes are not cracked, they can stay. But if there’s any sign of leaking, it’s time to replace them.
Copper Drain Lines
Used for only a short time, copper drains have some issues.
- Thin walls break down with soap and chemicals
- Can wear out faster than other types
- Often replaced with plastic today
If you have copper drain pipes, we recommend that you update them.
Plastic Drain Pipes: PVC and ABS
Plastic drain pipes are now the most common in new homes.
- PVC (white) and ABS (black)
- Easy to cut and glue
- Won’t rust or wear out like metal
- Affordable and simple to install
Pro Tip: If you’re updating your drains, plastic pipes like PVC or ABS are usually your best option. They’re reliable and easy to fix.
How to Choose the Best Plumbing Pipe for Your Home
Choosing the right plumbing pipe means thinking about more than just the cost. You also need to consider how long it will last and how well it fits your home’s needs.
- Water supply lines: Copper is the best option if you want a pipe that lasts a long time and can handle heavy use. If you want something more affordable and easier to install, PEX is a good choice. Galvanized and polybutylene pipes should be replaced right away, since they are known to cause problems.
- Drain lines: Cast iron can stay in place if it’s still solid and not cracked. If you have old copper drain pipes, it’s best to replace them with PVC or ABS. These newer plastic pipes are more durable and easier to work with.
