PEX Pipes vs. Copper: What’s Best for Your Plumbing Installation?

When installing or upgrading your home’s plumbing system in Augusta, Maine or the surrounding areas, choosing the right pipe material is a crucial decision. At Garand Plumbing, we often get asked: What’s better—PEX pipes or copper pipes? Both materials offer unique benefits, making them suitable for different plumbing installation scenarios. In this guide, we’ll help you make an informed choice by exploring the pros and cons of PEX and copper pipes, as well as their impact on efficiency, durability, and long-term costs.

Understanding PEX Pipes

PEX (cross-linked polyethylene) pipes have gained significant popularity in recent years for residential plumbing installations. This flexible plastic piping is commonly found in new construction and remodels throughout Augusta, Lewiston, Waterville, and neighboring communities. Here’s why homeowners and plumbers are choosing PEX:

1. Affordability 

PEX pipes are generally more budget-friendly to purchase and install compared to copper. Since PEX is easier to run through walls and tight spaces, labor costs are often lower as well.

2. Flexibility and Easy Installation 

One of the main advantages of PEX is its flexibility. It can bend around corners without the need for numerous fittings, reducing the likelihood of leaks. The installation process is also quieter and requires fewer tools.

3. Resistant to Corrosion and Scale 

Unlike copper, PEX will not corrode due to mineral-rich water or acidic conditions, which is important for Maine homes with variable water quality. PEX is also less susceptible to scale buildup.

4. Freeze Resistance 

PEX pipes can expand slightly, giving them better resistance to cracking in freezing temperatures—a valuable feature for homes in Central Maine’s colder climate.

5. Minimal Noise 

PEX dampens the sound of running water, leading to quieter plumbing throughout your home.

However, PEX pipes should not be installed outdoors where they’re exposed to UV light, as sun exposure can cause degradation. They’re also not recommended for direct connection to water heaters without a segment of copper pipe in between.

The Case for Copper Pipes

Copper pipes have been a plumbing staple for decades, known for their strength and reliability. Many older homes in Augusta, Gardiner, and Hallowell likely have copper plumbing. Here are some reasons why copper might still be a solid choice for your plumbing installation:

1. Proven Durability 

Copper pipes are long-lasting, with lifespans often exceeding 50 years when properly installed and maintained. They’re not susceptible to rodents or insects.

2. Withstands High Temperatures 

Copper performs well under high-heat conditions, making it suitable for hot water and for use with boilers or radiant heating systems.

3. Bacteria Resistant 

Copper has natural antimicrobial properties, helping maintain water quality during transport.

4. Recyclable and Environmentally Friendly 

Copper is a recyclable material, which can be important for sustainability-minded homeowners.

5. Fire Resistant 

Copper pipes do not burn or release toxic fumes, which can be an additional safety benefit.

That said, copper is more expensive—both in materials and installation. It can also develop pinhole leaks over time, particularly if your water is highly acidic or contains certain minerals. Additionally, installation typically requires soldering and more extensive wall access.

PEX vs. Copper: What’s Right for Your Augusta, Maine Home?

When choosing between PEX and copper for your plumbing installation, consider your home’s specific needs, budget, and local factors:

- If you want a cost-effective, versatile solution for a new build or remodel, PEX is often the preferred choice.

- For special cases—such as tying into existing copper pipes or for outdoor exposures—copper may be better.

- Homes in colder climates, like those across central Maine, may benefit from the freeze-resistance of PEX pipes.

- If longevity and proven past performance matter most to you, copper remains a trustworthy standard.
