How Much Does a Main Water Line Replacement Cost?

How much does a main water line replacement cost? This project may be a large expense for you, but the benefits far outweigh the costs. Learn more about the different types of pipe, how they are installed, and what they cost. Regardless of the type of piping your home has, it’s important to get a quote for the entire project so you can prepare yourself financially for any eventuality. In this article, we’ll discuss different types of piping, including PVC and copper.

Plumbing clogs

Clogged plumbing is often the result of a clogged main water line. The clog may be caused by accumulation of waste, tree roots, or a collapsed pipeline. If you have to replace the entire line, the cost may be around $100-$200 per linear foot. A plumber may charge between $2.00 and $3.50 per line foot if the main line is made of PEX piping.

For small clogs, the average cost for cleaning a main sewer line ranges from $150 to $750. A more significant blockage may require hydro jetting, which costs approximately $225 to $575. Signs that a main water line clog may be present include slow draining or no drainage at all, bad odors, or sediment in bathtubs. If you experience any of these signs, it is important to call a plumber right away.

A broken main water line is not an uncommon cause of low water pressure. If it is leaking, you’re not the only one with low water pressure. Broken water lines can also allow dirt to enter the drinking water, leading to strange smells and a grainy texture. This can lead to serious health risks. If a water pipe ruptures, it’s essential to replace it as soon as possible to avoid a costly situation.


While the initial leak might not be too severe, a large water bill may mean that the water line is failing and needs replacement. Another sign of a leaking water main is a sudden drop in water pressure. These signs are often related to more serious leaks. If you suspect a leak, call a professional plumber right away. A trained professional will use state-of-the-art equipment to determine the cause of the problem and recommend the best course of action.

Despite their size, leaks in a main water line can result in hundreds of dollars in repair costs. If the leak is under the house’s foundation, the plumber may have to dig out the floor to access the line, adding to the total cost. Likewise, if the leak is in a wall, he may need to replace the wall or flooring to get to the break. All of these things add to the overall cost.

Fortunately, the costs of fixing a leak in a water line can be lower than the cost of replacing a complete water main. Many homeowners decide to patch a leak rather than replace the entire pipe. This option is more affordable in the long run. Leaks in a main water line can cause a variety of health issues. Not only can mold and mildew affect the foundation of a house, but it can also cause severe allergic reactions in some people.

Copper piping

A new water line will increase the overall cost of replacing the water line. Whether you choose copper or PVC piping depends on your budget and where you live. Copper costs more than PVC, but it is also more durable and is ideal for colder regions. However, some soils don’t allow copper pipes, so PVC may be a better option for you. Copper costs more to install, but it is worth the extra expense.

If you don’t want to spend a lot of money on copper piping, consider other options. Copper piping costs between $20 to $30 per linear foot, and you can find cheaper alternatives online. You can even make your pipes into pieces of art and use them as conversation pieces. Even though copper piping for main water line replacement cost is higher, there are other materials that are equally as beautiful and durable. These are listed below.

Copper pipes have a longer lifespan and can be used in homes and businesses. Copper pipes are also resistant to rust and UV rays. They are durable and can withstand earthquakes. Copper pipes are more expensive than PEX or PVC but are more durable and last longer. Copper pipes are more flexible and can be used inside and outside your home. Copper pipes can withstand extreme temperatures without the need for replacement.

PVC piping

The total cost to replace a main water line can range from $1,500 to $3,000, depending on a variety of factors. The cost to install the water line can be split into two parts: the main water valve and the feeder lines. If the main valve is located underground, you may need to dig up the sidewalk and the main water line to access it. This process begins with a thorough inspection and the use of cameras to locate underground pipes.

The price of installing a new main water line is typically between $4 and $6 per linear foot. PEX plumbing is less expensive than copper, and the installation process takes only a day or two. However, some environmental groups are concerned about the unknown health risks associated with plastic water supply lines. PEX piping for main water line replacement cost has not been widely used in the United States for more than a decade, so its durability is unknown.

The type of material used to install a main water line will also determine the overall cost. PVC pipes are comparatively less expensive than copper, but they cannot withstand cold temperatures. Copper pipes are corroded easily if the pH level in the water increases. Depending on your specific needs and your budget, you can choose between copper and PVC. But remember that both types of material can be problematic depending on the climate, soil type, and other variables.


The costs of replacing a main water line in a private residence range from $600-$2,500. Permits for this project must be obtained before a contractor can begin work. In addition to the cost of the main water line itself, the homeowner must also pay for the portion of the line that extends beyond the property line. In some municipalities, obtaining these permits and inspections is free, but in most places, a permit must be obtained first. Since nearly every municipality requires permits for this project, contractors pull them as part of the estimate.

Some types of plumbing work don’t require permits, though. Minor repairs that do not alter the plumbing system, such as replacing a leaking pipe, or repairing a frozen pipe, do not require a permit. In addition, many of these repairs are emergency repairs. If you are not replacing a main water line, you should contact a licensed plumber to handle the work. Otherwise, you may need a permit for other plumbing work related to the main water line replacement.

When replacing a main water line, a permit is required before you can begin work. If you are not sure that you need a permit, you can always apply for an extension. If you get a permit for a project, you should be able to apply for it online. The process is simple and fast. A permit will be issued within two business days, and a permit inspection will be scheduled after payment.


The materials involved in main water line replacement cost are largely a matter of personal preference. The type of piping and the ease of access to the pipe are important factors that can affect the overall cost of the project. For instance, in some regions, digging through a concrete slab will increase the cost. Some materials, like PVC, are inexpensive but can break easily in some climates. Depending on where you live, you might want to consider copper piping instead of PVC piping.

While the materials involved in main water line replacement cost will vary, the overall cost is typically around $1,500. A 25-foot galvanized steel main line replacement cost may run approximately $3,750. If you choose trenchless installation, the cost will be much lower. Meanwhile, a 10-foot PVC pipe will only cost around $1,125. The cost to install a new water main varies depending on the size and depth of the line.

For homeowners looking for a more affordable option, the price of a private main water line replacement can be anywhere from $600 to $2,300. This cost includes the cost of digging out the old main water line and connecting it to the city water supply. A private main water line typically has little to no remaining life. If you’re replacing an old private main water line, you may be able to avoid a full-blown replacement by lining or bursting it yourself.
