Repiping A House – Everything  You Need To Know

Your home’s plumbing is aging and starting to show signs of wear and tear- you might need to repipe.

A home’s plumbing system is one of its most important features, but it’s often taken for granted until something goes wrong. Leaks, water damage, and rusty water are all common problems caused by an outdated or faulty plumbing system.

Repiping your home is a great way to solve these issues and give you peace of mind that your plumbing is in good shape. In this article, we will discuss everything you need to know about repiping your house, including when you should consider doing it and what to expect from the process. So, let’s get started!

Warnings Signs That You Might Need To Repipe Your House

There are a few signs that indicate it might be time to repipe your house. If you’re experiencing any of the following, repiping will likely solve the problem:

Frequent Leaks

Leaks are one of the most common problems that homeowners face, and a variety of factors can cause them. If you’re constantly dealing with leaks, your plumbing system might be to blame. You might need to repipe your home if the leaks are due to corrosion and are causing your pipes to wear out.

Water Pressure Problems

If your water pressure has dropped significantly or fluctuates often, it could be a sign that you need to repipe. Low water pressure can also be caused by blockage, leaks, or even a faulty water heater.

Rusty or Discolored Water

Another common problem that often indicates a need to repipe is rusty or discolored water. If the water in your home looks off-color or has an unusual odor, it’s possible that the pipes are starting to rust or corrode, which can cause contaminants to enter your water supply.

Poly B Pipes

One type of pipe that is particularly prone to leaks and other problems is poly b. If your home was built before the 2000s, your pipes are likely made of poly b. These pipes are banned and considered illegal to install in many places because they’re so prone to leaks and other issues.

Poly b is a less durable material than other types of piping, so it’s best to replace your poly b pipes as soon as possible.

These are just a few common signs that indicate you might need to repipe your house. If you’re experiencing any of these problems, it’s best to call a professional to take a look and assess the situation.

What to Expect When Re-piping Your House

Now that we’ve covered some of the signs that you might need to repipe your house let’s quickly go over what’s involved when re-piping your home and what you can expect during this entire process.

Consultation & Preparation

The first step in the repiping process is to consult with a professional to determine if repiping is the right solution for your home. They will assess your pipes, identify any problems or issues, and recommend a course of action.

If repiping is the recommended solution, it’s time to get started on removing your old plumbing system and installing the new pipes. This process usually involves carefully taking down all of the old pipes, making sure no damage is done to the walls or other structures.

Installation Process

The next step is to install new pipes that are made of durable materials like PEX, copper, or CPVC. This usually involves cutting into your existing pipes, removing them, and installing the new ones, so it’s important to leave this part of the project to a professional. You can expect the installation process to take 3-5 business days on average. 

Also, most days while the plumbing contractors are working your water will be turned off, so it is always a good idea to fill some jugs up with water so that you have something to drink or use during the day. When the day is over, most plumbing companies will re-pressurize the water so that you have a functioning sink, toilet, and shower by the end of the day. 

Testing & Cleanup

Once the new pipes are installed, it’s time to test them and make sure that they’re working properly. Professional plumbers will perform tests to ensure that everything is in proper working order before cleaning up any messes and restoring your home back to normal.

As you can see, repiping a house is a fairly involved process, but it’s a necessary step for homeowners who are dealing with plumbing problems. Be sure to consult with a professional to assess your needs and get started on the process as soon as possible.

Re-piping Options & Costs

Once you’ve decided that you need to repipe your house, the next step is to prepare for the process. This includes learning about the different types of piping material and selecting the best one for your needs as well as your budget. Here are the most common types of piping material:

PEX Piping

PEX or cross-linked polyethylene piping is a popular choice for repiping because it’s relatively affordable and easy to install. It is also a durable material that is resistant to freezing, leaking, and corrosion. This type of piping can be used for both hot and cold water lines.

Also, this type of plumbing system is recommended by the International Association of Certified Home Inspectors (InterNACHI) because of its reliability and high-quality material.

PEX repiping cost also varies depending on where you live and the size of your home, but it’s typically cheaper than other types of piping material. On average, most homeowners spend between $1,500 to $9,000+ to repipe a standard residential home.

PEX Piping Pros & Cons


  • Affordable: PEX piping is both cost-effective and long-lasting.
  • Easy to work with: PEX pipes are lightweight, flexible, and easy to maneuver. This makes them a good choice for complicated or difficult repiping jobs.
  • Resistant to corrosion: Since copper can react with certain substances in the water supply, PEX piping is a good choice for homes with hard water.


  • Susceptible to freezing: In areas where temperatures can drop below freezing.
  • Lower heat transfer properties: Since PEX pipes are made from plastic, they aren’t as good at transferring heat and water in comparison to copper pipes.

Copper Piping

Although copper piping can be more expensive than other types of piping, it’s a good choice if you want a low-maintenance and long-lasting piping system. Copper also has excellent heat conductivity and is a great choice if you want to install radiant heating in your home.

The cost of copper repiping can vary depending on the size of your home and the type of copper piping you choose. Expect to pay between $2,500 to $15,000+ for a standard copper repiping job in a home with three bathrooms.

Copper Piping Pros & Cons


  • Long lifespan: Copper can last for more than half a century without needing repairs or replacements.
  • Doesn’t react with water: Since copper doesn’t react with the minerals found in most water supplies, it is better suited for homes with hard water.


  • Expensive: Copper piping can be quite expensive compared to other types of pipes.
  • High heat transfer properties: While this may be a good thing in some situations, copper pipes are less efficient at storing and transferring heat than PEX or CPVC pipes.

Overall, the right type of pipe for you will depend on a variety of factors, including your budget, where you live, and how much heat transfer is needed in your home. Do some research and talk to a professional to find out which one is best for your needs.

How Long Does It Take To Repipe A House?

Repiping a house is a big undertaking and can take anywhere from a few days to several weeks, depending on the size and complexity of your home. A typical three-bedroom home may take a plumber or repiping contractor between 3-8 days to complete the job. For larger homes or those with more complex piping systems, the job may take closer to 2-3 weeks.

It is important to note that while repiping may be a time-consuming and disruptive project, it is often the best solution for addressing serious plumbing issues such as leaks, water pressure problems, or contaminated water.

Also, your water usage may be impacted during the repiping process as some water lines may need to be shut off while work is being done. However, your contractor should provide you with ample notice and make every effort to minimize any disruptions to your home and water supply.

Can I Repipe My Own House?

As mentioned above, repiping a house is a big job that requires the skills and experience of a professional plumber or contractor. There are many different types of piping material available, and each has its own unique set of installation requirements.

Additionally, repiping often requires opening up walls and ceilings in your home, which can be a complicated and messy process. Therefore, it’s generally not recommended that homeowners attempt to repipe their own homes.

If you’re considering repiping your house, the best thing to do is consult with a professional plumbing contractor in your area. They will be able to assess your needs and provide you with a detailed estimate for the job.

How to Choose The Right Plumbing Contractor?

When choosing a plumbing contractor to repipe your home, be sure to select a company with experience in repiping houses. Also, ask for references from past customers and check online reviews to get an idea of the quality of the contractor’s work.

In addition, be sure to get a written estimate from the contractor before work begins. This estimate should include the cost of materials as well as the estimated time frame for completing the job.

Finally, be sure to ask about any warranties or guarantees offered by the contractor. This will ensure that you are protected in case there are any problems with the repiping job after it is completed.
