Factors to Consider when Getting a Water Main Replacement or Repair

The first thing you need to know about repairing or replacing your water line is what size pipe you need. The second is what type of fittings will be required, and the third is whether or not a permit will be needed for the job. Pipe sizes are determined by the amount of water that needs to flow through them. The most common residential water line size is 1/2-inch diameter. However, homes with larger families or more water-using appliances may require a 3/4-inch diameter pipe. The type of fittings you’ll need will depend on the material your new water line is made from. If it’s made from copper, you’ll need copper fittings. For PVC pipe, you’ll need PVC fittings. And for PEX pipe, you’ll need PEX fittings.


You may or may not need a permit to replace your water line, depending on the municipality in which you live. In some cases, a permit is required regardless of whether you’re doing the work yourself or hiring a professional.

Replacing a water line is a big job, and it’s not one that most homeowners are equipped to handle on their own. If you’re not sure whether you can do it yourself, err on the side of caution and hire a professional. The cost of replacing a water line is significant, but the cost of repairing a mistake is even higher, and that is why it is best to leave all water main related issues to an expert.

Excavation Depth

The depth of excavation will depend on the type of pipe that needs to be replaced. For example, if you’re replacing a section of PVC pipe, you’ll only need to excavate enough soil to expose the pipe. However, if you’re dealing with a metal pipe, you may need to dig down several feet in order to reach the pipe. In any case, it’s always best to err on the side of caution and dig a little deeper than you think you need to. This will help ensure that you don’t have any problems when it comes time to replace the pipe.

Replacing a section of pipe can be a daunting task, but it’s well worth the effort if it means avoiding a costly and disruptive pipe burst. By taking the time to properly prepare for the job, you can ensure that the replacement process goes smoothly and that your new pipe will last for years to come.

Equipment Needed

When you’re ready to replace your water line, make sure you have all the supplies and tools you need before you start. This project will require:

  • A length of replacement pipe (copper, PVC, or PEX)
  • Pipe fittings (couplings, elbows, etc.)
  • A hacksaw or pipe cutter
  • Tape measure
  • Pipe wrench
  • Level
  •  Shovel
  • Replacement line (copper, PVC, or PEX)

Our work process

Working with us is a customised experience, from start to finish.

  • The first step is to shut off the water to your home at the main water valve. This will prevent any accidental flooding while you’re working.
  • Next, we use a tape measure to determine the length of pipe that will be needed to replace the old line.
  • Once we get the measurements, we can purchase the necessary materials.
  • When all the supplies have been gotten, it’s time to begin cutting the old pipe. Use a hacksaw or pipe cutter to remove the damaged section of pipe.
  • Once the old pipe is removed, we use a level to make sure the new section of pipe is level before attaching it.
  • To attach the new section of pipe, we use a pipe wrench. First,we apply some pipe joint compound or plumber’s putty to the end of the new pipe.
  • Next, we fit the new pipe into the old one and use the wrench to tighten the connection.
  • Once the new pipe is in place, we turn on the water and check for leaks. If there are no leaks, you’ve successfully replaced your old pipe!

      What causes a water main to burst?

      There are a number of reasons why a water main might burst, but the most common cause is simply old age.

      How often should water mains be replaced?

      There is no definitive answer to this question as it depends on a number of factors, such as the condition of the pipes, the climate, the water quality, and the amount of use. However, most experts agree that water mains should be replaced every 30–50 years. If you’re thinking about replacing your water main , we recommend contacting a professional to get an accurate estimate of the cost and time involved.

      What type of pipe is used for the water main?

      There are a variety of materials that can be used for water mains, including ductile iron, PVC, and HDPE. The type of pipe that is most appropriate for a particular project depends on a number of factors, such as the climate, the water quality, and the amount of use.

      Can you use PEX for the main water line?

      PEX can be used for main water lines in some cases, but it is not appropriate for all projects. For example, PEX is not recommended for use in areas with high water pressure or where the water quality is poor.

      What are the benefits of using PVC for water mains?

      PVC has several benefits that make it an attractive option for water mains. First, PVC is durable and can withstand high water pressure. Additionally, PVC is resistant to corrosion and is not affected by most chemicals. Finally, PVC is easy to install and does not require special tools or equipment.

      How deep should a main water line be?

      Main water lines should be buried at least four feet underground to protect them from freezing temperatures and damage. Additionally, water lines should be buried at least eight feet underground if they are located in an area that is prone to flooding.

      How long does it take to replace a water line?

      The time it takes to replace a water line depends on the length of the line and the type of material that is being used. PVC water lines can generally be replaced in a day or two, while metal water lines may take a week or more to replace.

      How long will PEX last underground?

      PEX tubing can last up to 100 years when properly installed. This makes it an ideal choice for use in underground applications. PEX is also resistant to corrosion and scale buildup, which can cause problems in metal water lines.

      Which is better, copper or PVC for water main lines?

      There is no definitive answer to this question as both copper and PVC have their own advantages and disadvantages. Copper is a more durable material, but it is also more expensive. PVC is less expensive, but it is not as durable as copper. Ultimately, the decision of which material to use for a water main line depends on the specific needs and budget of the homeowner.

      What is the best pipe to use for an underground water line?

      The best pipe to use for an underground water line is a cross-linked polyethylene (PEX) pipe. PEX is a durable, flexible, and corrosion-resistant material that can withstand high temperatures and pressures. It is also resistant to scale build-up, which can cause problems in metal water lines.

      What size is a mains water pipe?

      Main water pipes are typically either 1 inch or 2 inches in diameter, although some homes may have larger or smaller pipes. The size of the pipe will determine the flow rate of the water and the pressure of the system. Larger diameter pipes can carry more water, but they may require higher water pressure to function properly.

      Where does the main water line enter a house?

      The main water line typically enters the house at the water meter, which is usually located near the street. From there, the water line will run to the main shut-off valve, which is usually located near the home’s water heater. From the main shut-off valve, the water line will branch off to various fixtures and appliances throughout the house.

      Can water pipes be above ground?

      Pipes can be above ground, but they are more susceptible to freezing and thawing in cold weather. They may also be more vulnerable to damage from lawn equipment or other objects that can strike them. If pipes are above ground, they should be well insulated to protect them from the elements.
