Should I Repipe My House with Pex?

Should I Repipe My House with PEX? Benefits & Considerations

If your home’s plumbing system is aging, leaking, or no longer performing efficiently, you may be considering repiping your house. When it comes to choosing the right material for repiping, PEX (cross-linked polyethylene) has become an increasingly popular choice among homeowners due to its durability, flexibility, and cost-effectiveness. But is PEX the right choice for your home?

In this blog, we’ll explore the key benefits of repiping your house with PEX, compare it to other piping materials, and help you determine whether PEX is the best solution for your repiping project.

What Is PEX?

PEX piping is a flexible plastic tubing that has gained popularity in residential plumbing systems for its versatility and ease of installation. It was developed as an alternative to traditional materials like copper and galvanized steel and has since become a leading choice for both new builds and repiping older homes.

PEX is available in three types—PEX-A, PEX-B, and PEX-C—each with slightly different properties in terms of flexibility, strength, and installation methods. PEX-A is the most flexible, while PEX-B and PEX-C are more rigid but still highly durable.

Benefits of Repiping Your House with PEX

When considering whether to repipe your house with PEX, it’s important to understand the advantages that this material offers. Here are some of the key benefits that make PEX an attractive option for homeowners:

1. Flexible and Easy to Install

One of the biggest advantages of PEX is its flexibility. PEX pipes can bend around corners and obstacles without the need for as many fittings or connectors as rigid pipes like copper or PVC. This flexibility makes it easier and faster to install, reducing labor costs during the repiping process.

In addition, because PEX is lightweight and can be fed through walls without major demolition, it’s a popular choice for retrofitting and repiping older homes. Installers can often run PEX through existing structures with minimal disruption to your home’s walls and floors.

Why It’s Beneficial:

• Faster installation reduces labor costs.
• Fewer fittings mean fewer potential leak points.
• Flexible design makes it easier to install in tight spaces.

2. Resistant to Corrosion and Scale Buildup

Unlike copper or galvanized steel pipes, PEX is highly resistant to corrosion, rust, and mineral buildup. This makes it ideal for areas with hard water, like Arizona, where mineral deposits can cause significant problems for older metal pipes.

Copper pipes can corrode over time, leading to leaks, reduced water flow, and costly repairs. Galvanized pipes can also suffer from scale buildup, further reducing water pressure. PEX eliminates these issues, providing a long-lasting and reliable plumbing solution.

Why It’s Beneficial:

• Long-term durability with no corrosion or rusting.
• Prevents scale buildup, ensuring consistent water flow.
• Ideal for homes with hard water conditions.

3. Freeze-Resistant

PEX piping is more resistant to freezing than metal pipes. While no plumbing system is completely immune to freezing in extremely cold conditions, PEX has the advantage of being able to expand slightly when water freezes inside it. This flexibility means that PEX is less likely to burst during a freeze, which can significantly reduce the risk of water damage.

For homes in colder areas or properties that experience occasional freezing temperatures, PEX’s freeze-resistant properties provide extra peace of mind.

Why It’s Beneficial:

• Reduced risk of burst pipes during freezing conditions.
• Flexibility allows for expansion, protecting your plumbing system.

4. Cost-Effective Solution

Compared to copper piping, PEX is a more affordable option for repiping your home. PEX material itself is less expensive, and because it is easier to install, labor costs are also lower. This makes PEX a cost-effective solution for homeowners looking to upgrade their plumbing system without breaking the bank.

While copper has historically been the gold standard for plumbing, its rising cost has made it less practical for large repiping projects, especially when PEX offers similar performance at a fraction of the cost.

Why It’s Beneficial:

• Lower material costs than copper or steel.
• Faster installation reduces labor expenses.
• Ideal for homeowners seeking an affordable, high-quality repiping solution.

5. Quiet Operation

PEX pipes are much quieter than metal pipes, which can often make noise as water flows through them. Copper pipes, in particular, are prone to making popping or pinging sounds when they expand and contract due to temperature changes. PEX’s flexibility allows it to absorb these movements, leading to quieter plumbing operation overall.

If you’re tired of noisy pipes, especially in areas where plumbing runs through living spaces or near bedrooms, repiping with PEX can help reduce sound.

Why It’s Beneficial:

• Quieter water flow compared to copper and steel pipes.
• Fewer temperature-related noises from expansion and contraction.

6. Highly Durable and Long-Lasting

PEX piping is built to last. It has a lifespan of around 40-50 years, making it one of the most durable piping materials available. Its resistance to corrosion, scale buildup, and freeze damage contributes to its longevity, ensuring that you won’t have to worry about frequent repairs or pipe replacements once your home is repiped with PEX.

Additionally, because PEX doesn’t corrode like metal, it can handle different water pH levels without degrading, making it a reliable option for a wide range of water conditions.

Why It’s Beneficial:

• Long lifespan of up to 50 years, reducing the need for future repiping.
• Durable material that resists damage from various water conditions.

Considerations Before Repiping with PEX

While PEX offers many benefits, there are a few factors to consider before deciding to repipe your house with this material.

1. Exposure to UV Light

PEX is not designed to be exposed to direct sunlight for extended periods. Prolonged UV exposure can cause the material to degrade over time. For this reason, PEX is best suited for indoor plumbing systems or for buried outdoor pipes where it won’t be exposed to sunlight.

2. Potential for Rodent Damage

In areas with a rodent problem, PEX can sometimes be at risk of chewing damage. Rodents may chew through the piping, leading to leaks. While this is not a common issue in every home, it’s something to consider if you live in an area prone to rodent infestations.

3. Compatibility with Existing Plumbing

If you’re only repiping part of your home or doing a renovation, it’s important to ensure that PEX is compatible with the rest of your plumbing system. You may need to use adapter fittings to connect PEX to existing metal or PVC pipes, which can add to the complexity of the installation.

Conclusion: Is PEX Right for Your Repiping Project?

If you’re looking for a cost-effective, durable, and flexible solution for repiping your home, PEX is an excellent option. Its resistance to corrosion, easy installation, and long lifespan make it a popular choice for homeowners looking to upgrade their plumbing systems. However, if your home has unique conditions such as direct sunlight exposure or rodent problems, it’s important to weigh these considerations when deciding.
