PEX in Attic or Crawl Space

PEX is a new innovation in plumbing technology. It’s an acronym for Cross-linked Polyethylene, and it’s commonly used for water supply systems, especially in repiping a house through the attic. PEX has gained popularity due to its excellent durability, flexibility, and resistance to corrosion. It’s also effortless to install, making it a favorite of plumbers and homeowners alike.

Benefits of PEX

PEX is an excellent choice for repiping a house. Here are the reasons why:

Easy Installation

PEX is incredibly flexible and easy to install, whether you’re repiping through the attic or crawl space. Plumbers can bend it around corners and easily snake it through tight spaces, significantly reducing the need for joints, making it less prone to leaks.


PEX is less expensive than other materials used for plumbing, like copper. It’s a cost-effective alternative that still provides durable and efficient pipe systems.


PEX has an average lifespan of 20–25 years, making it an excellent investment for repiping a house in the attic or crawl space. Its resistance to corrosion extends the lifetime of the pipe further, providing significant longevity.

PEX vs. Copper

Copper has been the go-to material for repiping houses through the attic and crawl space before the advent of PEX. PEX has become a compelling alternative to copper. Here’s a brief comparison between the two:

PEX is More Flexible

PEX is exceptionally flexible, making it an excellent choice for repiping a house through the attic or crawl space. In contrast, copper is rigid and challenging to install in tight spaces.

PEX is Corrosion-Resistant

PEX has a high resistance to corrosion, unlike copper. This means that your plumbing will last longer, and you won’t have to worry about replacing it after a short period.

PEX is More Affordable

PEX is less expensive than copper, and since it requires fewer fittings, tools, and connections, installation costs are lower.

In conclusion, PEX is an excellent option for repiping a house through the attic or crawl space due to its flexibility, cost-effectiveness, and resistance to corrosion. Its installation process is easy, and the durability is unparalleled. Plumbers prefer PEX because it saves them time and effort and enables them to complete a repiping job faster. Homeowners like PEX because it saves them money and lasts longer than other plumbing materials.

Water Pipes in Attics: What You Need to Know

If you live in Florida and have recently repiped your house through the attic, it’s essential to understand the importance of the water pipes in the attic. Here are some key things to keep in mind:

Insulation is Critical

Florida’s high humidity and extreme summer temperatures can significantly impact the functionality of your water pipes. Installing proper insulation around the entire water pipe network in the attic is crucial to prevent problems caused by moisture buildup.

Watch Out for Leaks

Leaks in the water pipes can cause significant damage to your home’s structural integrity and increase your water bills. Regularly checking your pipes for leaks is an important preventative measure. Be sure to keep an eye out for water damage or mold growth around the pipes.

Consider Replacing Your Pipes

If you have an older home with aging pipes, repiping may be the most effective solution. Newer pipes will likely be made of more durable materials and can withstand Florida’s extreme temperatures, reducing the likelihood of leaks or other damage.

Annual Maintenance Checks

One of the best ways to prevent pipe issues is to schedule annual maintenance checks with your plumbing professional. This will help to catch any potential problems early on before they turn into more significant issues.

If you’re repiping your home, you may need to run new water lines in your attic. This can be a daunting task, but with the right knowledge and tools, it can be done relatively easily. Here are some things to keep in mind when running PEX water lines in your attic.

What is PEX

PEX (cross-linked polyethylene) is a flexible plastic tubing that is commonly used for water distribution in plumbing systems. It is cost-effective, easy to install, and highly resistant to heat and cold. PEX is a great option for running water lines in your attic because it can be bent around corners and obstacles without the need for couplings or connectors.

You’ll also need to determine the best path for your water lines and ensure that there is enough space to run them without damaging any existing wiring or insulation.

Installing the Lines

To install the lines, you’ll need to first measure the length of tubing you need and cut it to size. Next, use a PEX crimping tool to attach the appropriate fittings to the ends of the tubing. Then, carefully run the tubing along the path you’ve chosen, securing it with clamps or straps where necessary.

Pressure Testing

After installing the PEX water lines in your attic, it’s important to perform a pressure test to ensure everything is working correctly. Simply cap off the ends of the lines and attach a pressure gauge to one end. Slowly open the water supply valve and monitor the pressure gauge to ensure it holds steady.

Running PEX water lines in your attic may seem daunting at first, but with the right preparation and tools, it can be done quickly and easily. By following these tips and taking the time to do the job right, you’ll have reliable and efficient water lines in your home for years to come.

After that, the plumber will cut into the pipes and remove the old ones. This phase can be loud and messy, but your plumber will take all necessary measures to minimize disruptions.

Installation of New Pipes

After removing the old pipes, the new pipes are installed. These replacements could be copper, PVC, or any other material that the plumber recommends. The plumber will ensure that the new pipes are correctly installed and will run tests to detect any leaks.


Once all the pipes are replaced, the plumber will clean up after themselves. Any damaged drywall or flooring will be replaced, and the work area will be left neat and tidy.

Repiping your house through the attic can be stressful, but knowing what is involved in the process can make it less overwhelming. With the help of professional plumbers, you can rest easy knowing that your pipes are in good hands.

Can You Replumb a House Without Removing Walls

As a homeowner, the thought of replumbing your house may give you nightmares. The idea of having to break down walls and spending thousands of dollars may seem overwhelming. Fortunately, you don’t need to go through such drastic measures to replumb your house.

Approach It Differently

One of the most commonly asked questions by homeowners is whether you can replumb a house without removing walls. The answer is a resounding yes. In fact, new techniques and technology have made it possible to replumb your house without tearing down walls or going through any unnecessary disruptions.

Pipe Lining and Pipe Bursting

Two popular methods of replumbing a house without removing walls are pipe lining and pipe bursting. Pipe lining involves repairing damaged pipes from the inside. A flexible tube coated in resin is inserted into the damaged pipe and inflated. The coating then hardens, creating a new pipe within the existing one.

Pipe bursting, on the other hand, involves breaking the old pipe while simultaneously laying the new one in its place. It’s a trenchless method that doesn’t require any digging on your property. The new pipe is strong and durable, and replumbing your house using this technique can save you a lot of money.

Other Alternatives

Apart from the above methods, there are other ways to replumb your house without removing walls. The first step is to call a licensed plumber to inspect the plumbing system. They may have to cut small holes in the wall to access the pipes, but these can be easily covered up after the job is done.

If you’re not comfortable with cutting holes in the walls, you can try in-pipe coating. This involves spraying a coat of epoxy inside the pipe to seal leaks and prevent further damage. This method is ideal for small leaks and cracks, but it’s not recommended for major plumbing issues.

In conclusion, it’s possible to replumb your house without removing walls. Pipe lining, pipe bursting, in-pipe coating, and other modern techniques can fix your plumbing problems without causing significant damage to your walls or property. However, it’s essential to consult with a licensed plumber who can determine the best method based on the extent of your plumbing system’s damage. With the right approach, replumbing your house can be a stress-free and budget-friendly experience.
