How long can copper pipes last?
Copper pipes last roughly 70-80 years, so if your house was constructed fairly recently, your copper pipes are probably in good shape.
How long do copper pipes last? Residential copper pipes typically last from 20-50 years depending on the type. Certain types of copper piping are more susceptible to corrosion than others. A professional plumber can help determine if your home is equipped with a thinner variety that will degrade faster.
- Copper Pipes: 70-80 years.
- Brass Pipes: 80-100 years.
- Galvanized Steel Pipes: 80-100 years.
It's no secret that copper plumbing pipes are the go-to option when it comes to installing underground water lines. This is because copper pipes generally last 50 years or more. It is resistant to corrosion.
In general, copper pipes can last for several decades before showing signs of corrosion. However, if the water chemistry is highly acidic or if the pipes are exposed to harsh chemicals or extreme temperatures, the rate of corrosion can increase significantly. In these cases, copper pipes may corrode within a few years.
Copper pipes can last anywhere from six months to the life of a building. But PEX tubing, when operating within its pressure and temperature ratings, has a predicted life expectancy of 50 years per PPI TR-3.
L-type copper pipes are of medium thickness and can last for 50-100 years. As the thickest variety of copper piping, K-type pipes can last for over 100 years.
Therefore, by definition, a pure metal cannot age harden. Some copper alloys can be age hardened, but not, as far as I'm aware, pure copper.

Installing a New Copper Water Line
Copper fixtures can last 50-70 years in the right conditions. It is not toxic like lead and is resistant to corrosion, unlike iron and steel.
Why do plumbers still use copper pipes?
Durable: Copper is the most dependable and most used material for plumbing tube in the developed world. Copper is beneficial in underground applications because it is highly corrosion resistant in most underground environments. Because of its superior strength it can withstand stresses without failure.
Copper was the plumbing pipe of choice from the 1950s until 2000 and was widely used both in new construction and to replace the galvanized steel water supply pipes that had been the standard into the 1950s. But copper's use has gradually faded, due to the introduction of PEX plumbing tubing.
With proper installation, copper plumbing should last you at least 50 years, though it can last you upwards of 60 or 70 years if you maintain your pipes properly.
The green or greenish-blue substance that you see on copper pipes is the result of oxidation. It occurs when the metal is exposed to water and oxygen for a long period of time. Over time, these elements cause the copper to break down, which results in the formation of this green substance.
Water moving through a pipe at unusually high velocity can wear away copper from the interior of the pipe. If the pipe ends weren't properly reamed smooth prior to soldering, the raised burrs inside the pipe can cause local turbulence, called erosion corrosion, which will corrode the pipe.
In most cases, PEX is extremely durable and lasts up to 50 years or more. PEX piping is also less likely to crack or break than metal pipe because it does not expand and contract as much when heated and cooled.
Blue or green staining occurs exclusively with copper pipe and fittings (including brass, which is copper + zinc), and is caused by the corrosion and dissolution of the metal itself.
Copper pipes have been used in both commercial and residential plumbing/piping systems for decades. This is why most plumbers prefer copper pipes to PEX pipes because of the familiarity of copper pipes. They are the most common types of materials found in the plumbing systems of water supplies in homes.
If just a pipe or a section of your copper plumbing system is leaking, you could just replace it with PEX piping. But if you have an old copper plumbing system that leaks frequently in different areas of your home, you may want to consider a whole-house repipe.
PEX cannot be taken anywhere outside the house where it is directly exposed to UV for a long period. The synthetic material of the pipes can slowly disintegrate due to the light of the sun. Even light bulbs have been known to affect the lifespan of PEX water lines.
Which pipe has longest life span?
Drainage pipes are often made of cast iron or polyvinyl chloride, or PVC. Cast iron will last anywhere from 75-100 years while PVC wins the award for longest-lasting pipe material with an indefinite lifespan.
And yet, copper pipes can easily burst in a freeze. Plumbing pipes made from copper lose heat quickly. The material doesn't expand when water freezes, instead the pipes burst or split open.
1) Durability
The first is the lifespan of the materials. Copper piping has an impressive lifespan of 50+ years, making it one of the longest-lasting pipes on the market. In comparison, PVC pipes tend to fall apart much more easily. Of course, we also have to consider how well each type of pipe stands up to damage.
Drinking water with more than 1,300 micrograms of copper per liter of water (µg/L) * can be a health risk for everyone. Infants and people with Wilson's disease may need water with an even lower level of copper to stay safe. Copper can get into your drinking water as it passes through your plumbing system.
Copper pipes have been the proven standard of reliability for over 50 years! They are not prone to leaks, are extremely durable, stay fitted tightly, have a long life span and can be recycled, are resistant to heat, and won't pollute your drinking water.
Of course, PEX piping does carry some disadvantages. It will crack and break apart under the influence of strong UV rays (making it unsuitable for most outdoor use). Plumbers require specialized tools to cut and join this type of modern pipe. Additionally, disposing of used PEX pipe sometimes proves problematic.
This is when the copper is subjected to repeated stress from being hammered or bent back and forth until its structure changes at a molecular level. The more stress that is applied, the stronger the final product will be since it will have undergone a larger structural change.
Heat Resistance: Many commercial buildings, like restaurants, rely on copper pipes for plumbing because they can handle high heat. These pipes can withstand temperatures up to 400 degrees Fahrenheit.
Effects of Oxidation on Copper
Instead, it peels off and weakens the metal, leaving it vulnerable to further rust and decay. Copper oxidation, however, creates a decorative patina coat that not only retains aesthetic appeal, but also prevents further exposure to oxygen and curbs corrosion.
Under the right (worst) conditions, your copper pipes may develop a pinhole leak within only two years of installation. Pinhole leaks in copper pipes are a common problem all over the US.
How do you prevent pinholes in copper pipes?
A few ways to prevent pinhole leaks include knowing your pipes' age, reducing the water velocity, checking the fittings, and installing a water softener system.
Green – Green or greenish colors on the outside of your copper water pipes means that you have water leaks in your copper piping and possible corrosion. The latter is especially true if the water itself is staining other items, like clothing, sinks, and fixtures.
PEX pipe is a newer alternative to copper and galvanized piping. First introduced in the 1980s, most plumbers now fit new construction homes with PEX, as well as remodeling projects. PEX pipe is a cross-linked polyethylene flexible tubing that is blue and red in color.
If the primary issue is localized to just one area of the house, then it may simply be a singular pipe or joint segment that needs to be replaced. However, if leaking pipes are a problem all over and there are issues such as corrosion or water discoloration, then repiping your entire house is likely necessary.
In addition to removing the old pipes, installing PEX tubing as the primary replacement material costs between $1.50 and $4 per linear foot or $1,500 to $4,000 for 1,000 linear feet of pipe.
While their acceptable use areas overlap, PVC is not always a suitable replacement for copper pipes. This material may work better than copper in some areas, but PVC doesn't fit in tighter spaces and is not suitable for a water supply line.
Many older homes may have existing copper pipes, while many newer homes are fitted with PEX pipes.
With its flexibility, durability, long coil lengths and lighter weight, PEX has quickly become the preferred piping choice for residential plumbing and commercial domestic water systems, including risers, distribution piping, in-suite and even underground applications.
Short-term exposure to high levels of copper can cause gastrointestinal distress. Long-term exposure and severe cases of copper poisoning can cause anemia and disrupt liver and kidney functions.
Copper pipes have a long-standing history of working well in homes. More popularized than other metals thanks to its softer material and flexibility, copper pipes are slightly more resistant to water corrosion than other metallic pipes and generally is durable for the long-term whereas plastic pipes are not.
What is the best replacement for copper pipe?
The alternative to copper (and PVC) is PEX pipe – a flexible, extruded piping material made from cross-linked polyethylene. Both copper and PEX have their advantages, considerations, and caveats – outside of cost alone.
Copper is a great material for plumbing. However, it has a big disadvantage: it loses heat quickly. Also, it has a thin wall and is not as flexible as the other materials. These combine to make copper the most prone to bursting in frozen weather.
Better Energy Efficiency – PEX has a lower thermal conductivity rate than copper. As a result, PEX pipes can help keep hot water hotter for longer periods of time. They also produce less condensation on cold water lines, which could lead to fewer moisture-related problems in ceilings and walls.
No matter what type of pipes you have in the property, plastic or copper, they will freeze and burst if there is water inside them. When temperatures plummet extreme pressure is built up in pipework due to frozen water causing it to burst.
