Why Do Waterlines need to be replaced?

Why Do Waterlines need to be replaced?

Water lines are an essential component of any home’s plumbing system, responsible for delivering clean, safe water for cooking, bathing, and drinking. Over time, however, these pipes can become worn, corroded, and damaged, leading to a range of issues that require replacement. In this blog post, we will discuss some of the reasons why a waterline might need to be replaced in a home, the top signs that you need waterline replacement, and FAQs about waterline replacement and repair services.

Age of the Waterline

One of the most common reasons for waterline replacement is age. Depending on the material, waterlines can last anywhere from 20 to 100 years. Older homes may have waterlines made of galvanized steel, which can corrode over time and eventually fail. Copper and plastic pipes tend to last longer but can still develop leaks and cracks as they age.

Corrosion of the Line

Corrosion is another common problem that can lead to waterline replacement. Corrosion occurs when the pipes are exposed to acidic or alkaline water or other corrosive substances in the soil. Corrosion can cause the pipes to weaken, develop leaks, and eventually fail.


Leaking pipes can cause a range of problems, from high water bills to water damage and mold growth. Leaks can be caused by a range of factors, including corrosion, age, and damage from tree roots or other underground elements. In some cases, a single leak may be repaired without replacing the entire water line, but in other cases, replacement may be necessary. This all depends on whether the exact location of the leak can be determined by your local plumbing company.

Common Signs of Waterline Damage

There are several signs that a waterline in a home may need to be replaced. Here are some of the most common signs:

  • Low water pressure: If the water pressure in your home has suddenly decreased, it could be a sign of a blockage or leak in your water line. Low water pressure could also be caused by corrosion or damage to the pipes, which can lead to reduced water flow.
  • Discolored or foul-smelling water: If the water coming out of your faucets is discolored, has a strange odor, or tastes unusual, it could be a sign of a deteriorating water line. Discoloration can be caused by rust, sediment, or other debris that has built up in the pipes over time. Most people do not realize that foul odor coming from your faucets is a clear indicator that a bigger problem is occurring. It is important to contact your local plumbing company to come out and run a diagnostic. Finding the issue sooner than later is always ideal.
  • Water leaks: If you notice water pooling or damp spots in your yard or basement, it could be a sign of a leak in your water line. Leaks can also cause mold growth, water damage, and high water bills. Water leaks are not something that should be ignored as the long term damage can be costly.
  • Aging pipes: If your home is more than 50 years old, it may have water lines made of galvanized steel, which can corrode and eventually fail. Copper and plastic pipes can also deteriorate over time and may need to be replaced. We suggest getting an inspection of your plumbing if your home is more than 50 years old, especially if you do not have a full report of previous work done on the plumbing by any previous owner.
  • Strange noises: If you hear banging, clanging, or other unusual noises coming from your pipes, it could be a sign of a waterline problem. This could be caused by high water pressure, air in the pipes, or other issues that can damage the pipes.
