Out With the Old, in With the PEX: Upgrading Your Galvanized Pipes

 In Uncategorized

If your home still has galvanized pipes, you could be sitting on a ticking time bomb. Galvanized pipes are the leading cause of low water pressure, rusty water, and costly leaks. Fortunately, there is a more innovative, cleaner, and more efficient piping solution available — PEX piping. 

In this guide, we will discuss why you should repipe galvanized to PEX, why PEX piping is beneficial, and answer some common questions about the process. Switching to PEX isn’t just a modern upgrade; it is a long-term benefit for your home’s comfort, performance, and value. Let’s jump in.

What Are Galvanized Pipes?

Galvanized pipes were commonly installed in homes before the 1960s and remained widely used until 1990. They are steel or iron pipes with a protective zinc coating (galvanization) that helps prevent rust and corrosion. While adding a galvanized layer is intended to avoid corrosion, over time, it can tarnish, and rust can form within the pipe. This can cause the water that runs through to become contaminated with lead, which is dangerous for humans and pets. Studies have found that the amount of lead in galvanized pipes ranges from 0.5%-2% which is more than what is recommended by the Environmental Protection Agency (EPA). Galvanized pipes are also sometimes connected to lead service lines, which can contaminate local water.

Should I Replace Galvanized Piping With PEX?

If your home was built before 1990 and has original galvanized piping, repiping to PEX can be a safe option. Replacing your old galvanized piping can provide many health and safety benefits and is a relatively inexpensive fix for a big reward.

Why Repiping From Galvanized Pipes to PEX Is a Great Option

PEX — cross-linked polyethylene pipes — is a flexible plastic tubing used for water supply lines in homes and buildings. It binds molecules in a bridge-like structure to form a stable, safe, and effective piping system. It’s resistant to:

  • Chemicals
  • Corrosion
  • Hot/cold extreme temps
  • Deformation from long-term exposure to stress 

Developed in 1960, it is an excellent replacement for copper or galvanized pipes and has been an industry standard in the USA since the 1980s.

 

7 Benefits of Repiping From Galvanized to PEX Pipes

#1: Flexible

PEX pipes are highly flexible — they can be bent and shaped around corners without the need for multiple fittings or joints. Installing these pipes allows for a faster, more straightforward, and less invasive installation, making them a great pipe upgrade choice in an older home.

In addition, the pipe itself can expand without breaking, which is essential for homes that experience freezing temperatures. 

#2: Durable

PEX pipes are built to last due to their high-quality cross-linked composition. These pipes can avoid common problems that other pipes experience, including:

  • Rust
  • Corrosion
  • Leaks
  • Scale 
  • Pitting 
  • And more

In addition, PEX pipes can expand and contract with pressure changes, allowing them to absorb the pressure fluctuations mentioned above. This is an excellent benefit for homes in colder climates, ensuring they can withstand temperature changes without cracking or bursting.

Beyond its ability to withstand temperatures, PEX’s durability also means less maintenance and longer system lifespans. Homeowners can enjoy reliable performance for decades without worrying about deterioration. If you are ready to make the switch, contact our team of professionals today, and we can get started. 

#3: Cost-Effective

When it comes to re-piping, installing PEX piping is one of the most budget-friendly and efficient upgrades available today. It is 20-40% less expensive than other options, such as galvanized steel and copper. This makes it an excellent choice for homeowners wanting to modernize their plumbing system without overspending.  

In addition to lower material costs, PEX is easier and faster to install. It allows plumbers to run continuous lines throughout the wall with minimal fittings and joints. This can directly reduce labor time and costs. 

Homeowners can appreciate the long-term savings that come with repiping from galvanized pipes to PEX. PEX avoids common problems — such as corrosion, leaks, and scale buildup — associated with other piping materials, reducing repair and maintenance costs. 

#4: No Noise

No one enjoys hearing rushing water down their wall after a toilet flush or valves banging as they open and close. Fortunately, PEX piping can significantly reduce these disruptive noises. Unlike metal pipes, which tend to amplify sound, PEX piping can absorb the vibrations and pressure due to its flexibility. Homeowners may experience significantly greater comfort and peace immediately after repiping from galvanized to PEX. 

#5: Eco-Friendly

PEX piping not only benefits your home and wallet, but it is also sustainable for the planet. Its design and production have a lower environmental impact compared to traditional metal piping options. PEX is eco-friendly due to:

  • Lower energy use in production: Metal pipes traditionally require high temperatures and refining, whereas PEX is made with significantly less energy.
  • Resource-efficient materials: PEX is made from durable, long-lasting plastic that requires fewer raw materials.
  • Improved water efficiency: Its smooth inner surface allows water to flow freely without buildup, reducing water waste. 
  • Lightweight and easy to transport: Its lightweight qualities mean transporting the piping uses less fuel and oil than other options. 

#6: Long Lifespan

PEX piping sets itself apart from its competitors due to its exceptional longevity. Unlike galvanized steel or copper, PEX has corrosion-resistant properties that can help it last 40-50+ years with proper maintenance. This long-lasting piping can significantly help to reduce the need for replacements and waste, making it one of the longest-lasting plumbing solutions available today. 

To maximize the lifespan of your PEX system, follow simple maintenance steps:

  • Keep PEX pipes away from UV exposure.
  • Check fittings and connections.
  • Insulate the piping to prevent freezing.

#7: Lower Utility Bills

Repiping your home from galvanized to PEX can lead to significant savings on monthly utility costs. Here are a few key ways PEX contributes to lower utility expenses:

  • Faster hot water delivery to reduce water waste and energy use
  • Improved heat retention, which helps the water heater work more efficiently
  • Reduced leaks and water waste, with fewer potential leak points in the piping
  • Efficient installation and maintenance

Over time, these benefits combine to make PEX a cost-saving investment that benefits both your home and your utility budget.

 

FAQs Regarding Replacing Galvanized Pipes With PEX

How Do You Know When It’s Time To Replace Your Galvanized Pipes?

While galvanized pipes were a popular choice for homes in the past, it may be time to replace them. To know if they are ready for an upgrade, look for some of these signs:

  • Frequent leaking
  • Corrosion
  • Low water pressure
  • Discolored water from pipes
  • Water tastes or smells bad
  • Water temperature fluctuations
  • Visual rust spots on piping
  • Old age (over 50+ years old)
