Should I Switch to Copper Plumbing?

Copper plumbing has increasingly become popular due to its longevity and performance properties. So, if you are asking yourself whether or not you should renovate to copper plumbing, just ask the millions of property owners who have already made the switch. They will tell you that copper plumbing increases resale value, requires less maintenance than conventional materials, and might even render certain tax benefits.

But before you decide to move forward with copper re-piping, be sure you know which type of copper plumbing is most compatible with your property in terms of connectivity, local environmental conditions, personal preference, and overall budget.

Copper Plumbing Options

There are three primary types of copper plumbing used in the residential and commercial markets. These include L-Type, M-Type, and K-Type copper plumbing. All copper plumbing lasts a long time, but not all shares the same level of longevity. How long your copper plumbing lasts will ultimately depend on the type you choose to install.


This type of copper plumbing will last at least 50 years, and even up to 100 years in regions with moderate climate conditions. Due to the thickness and durability of the design, as well as its universal acceptance among building codes, most professional plumbers will recommend L-Type copper plumbing for homes and businesses. Such piping can also withstand acidic water, delivering greater assurance against premature repairs and performance issues.


This copper plumbing is less expensive than L-Type, and accepted under most residential building codes (but not all). It generally lasts at least 50 years; however, it is possible for M-type copper plumbing to require replacement after only 20 years. If you live in an area with acidic water, or use a private well, this type of piping is not recommended. Because it is the thinnest of all three types, it is least resistance to acidity, and therefore, highly prone to corrosion.


As the thickest in piping material, it is not a surprise that K-Type copper plumbing lasts up to 100 years or more with good care. Yet, it is not the best option for all property owners. This type of copper plumbing is usually used in non-residential applications, such as city water mains and sewer lines. Its thickness and durability allow it to withstand high levels of pressure, which is why it is used in larger-scale systems. Residential properties do not require this level of power.

Professional Recommendation for Homeowners

If you are a homeowner, the L-Type copper plumbing would be your best option. That is because it is reasonably priced, lasts a long time, and accepted under all building codes. Talk to a state-licensed master plumber for personalized advice you can trust.
