Can hard water damage copper pipes?

So what is “hard water” and why does it corrode your copper pipes? Hard water is water with a high concentration of dissolved minerals like calcium, magnesium and other metals. Over time, these metals can wear out the inner lining of copper pipes, eventually creating pinhole leaks.

How long do copper pipes last with hard water?





20-50 years

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.

Do water softeners ruin copper pipes?

Softened water may contain metals because water is a universal solvent. When water is heated or softened, it is more prone to leach metals from water pipes and other parts of the indoor plumbing system. Copper in pipes, lead in soldered joints, and metal faucets are especially vulnerable to heated or softened water.

Can hard water ruin your pipes?

Very simply put, hard water is water that contains a high concentration of certain minerals, namely calcium and magnesium. While hard water is safe for human consumption, it can leave unsightly, hard-to-clean spots on your fixtures. Even worse, over time hard water can leave deposits that can damage your pipes.

How long should copper pipes last?





70 to 80 years

Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 45 years. In most new construction, this is seldom a problem, but if you live in an old home you might want to see what pipe material your house has.

What pipes are best for hard water?

Invest in PEX Pipes & A Water Softener to Prevent Mineral Buildup in Your Pipes. If you choose to have a clogged pipe in your home replaced, we recommend investing in PEX plastic pipes. This type of pipe is more resistant to a buildup of hard water minerals such as copper, iron, calcium, and magnesium.

Can copper pipes last 100 years?

As a general rule, copper pipes will last 70 to 80 years before they need replacing. However, some copper pipes have been known to last much longer and can be in working condition after 100 to 150 years. When copper pipes are nearing the end of their life, they will develop pinhole leaks.

Does hard water cause pipe corrosion?

Whilst hard water is not itself a health concern, it can cause corrosion in water pipes and home appliances, which creates major problems and costly defects. When you have hard water, it means that your home water supply contains Calcium and Magnesium from limestone, chalk or marble deposits.

How do I prevent calcium build up in my pipes?



Long-term solutions

  1. Install PEX piping. Modern pipes made out of PEX plastic are more resistant to limescale than copper pipes.
  2. Installing a water softener system. These units remove or counteract the hard minerals from the water as it enters the home, thereby reducing the risk of calcium build-up in the plumbing.

How do you remove calcium deposits from copper pipes?

Boil a pot of water. Pour a ½ cup of vinegar and a ½ cup of baking soda into the drain. Put cleaning rag over the top of the drain to cover it. Wait 5 minutes or so while the mixture eats away at the buildup.

Does water softener clean pipes?

It is critical to understand that a water softener itself will not remove limescale buildup within our plumbing fixtures and pipework. It is the soft water that a water softener will produce that will run through the pipes that will gradually dissolve the existing scale buildup.

What causes copper water pipes to corrode?



Once you navigate through the media noise and scientific engineering jargon, it’s clear that copper pitting corrosion is caused by a combination of factors–including improper pipe installation, bacteria, electrical grounding, soil acidity, pipe manufacture quality, water chemistry, the environment and more.

What is the longest lasting plumbing?

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.

How much does it cost to replace copper piping?

Copper is the most expensive piping material available, prices ranging from $5,000 up to $20,000 to repipe a house. While copper piping is durable, the material is rigid – driving up the cost. Installation requires wall demolition in addition to almost twice the amount of time compared to installing PEX piping.

Is it worth it to replace copper pipes with PEX?

Coupled with low production and shipping costs, the savings resulting from installing PEX instead of copper pipes can be significant. 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.

Which is better copper or PEX pipe?



PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.

When should I repipe my house?

You might need whole-home repiping if:

  • You’re experiencing decreased water pressure.
  • Your water bill has suddenly increased.
  • You see water stains on walls, floors, or ceilings.
  • Your pipes are outdated.
  • You have frequent pipe leaks.
  • You can see corrosion on your pipes.
  • You have rust-colored water.

How much does it cost to repipe an entire house?

The average cost to replumb a house will vary between $5,000 to $7,000. However, the total cost of repiping a house may be as high as $15,000 depending on a variety of factors. These variables include pipe location, number of bathrooms, quantity of fixtures, and how many stories a home includes.
