When it comes to plumbing materials, copper has long been a top choice due to its durability, corrosion resistance, and reliability. However, not all copper piping is created equal. Two of the most common types used in residential and commercial plumbing are Type L and Type M copper. While both have their place, at EZP Plumbing, we prefer Type L copper for all our installations, even though we are primarily a residential service company. Here's why we make this choice and why it can benefit your plumbing system.
What’s the Difference Between Type L and Type M Copper?
The difference between Type L and Type M copper lies primarily in their thickness, which directly affects their durability, strength, and longevity.
Type L Copper
This is thicker and stronger than Type M. The wall thickness of Type L copper ranges from 0.040 inches (for 1/2" pipe) to 0.065 inches (for 1-1/4" pipe). This added thickness makes Type L copper more resistant to pressure, physical damage, and the effects of time.
Type M Copper
Type M copper has a thinner wall thickness than Type L, typically around 0.032 inches for 1/2" pipe. While this makes it lighter and easier to work with, it sacrifices strength and long-term durability.
Commercial vs. Residential: When Are These Types Relevant?
When choosing copper piping for plumbing systems, the application is key.
Commercial Applications
Commercial plumbing systems often require heavy-duty materials because they are subject to higher demands, larger systems, and more intense wear and tear. Type L copper is generally the preferred choice in commercial settings due to its added durability, ability to withstand higher pressure, and longevity. In these environments, cutting corners on materials can lead to premature failure and costly repairs, so opting for thicker, more robust pipes is essential.
Residential Applications
While Type M copper is commonly used in residential settings because it is less expensive and easier to work with, it can have its drawbacks. For standard homes, Type M may seem sufficient for general water distribution, but its thinner walls make it more susceptible to damage from external forces (like impacts) or internal pressure spikes. Over time, this can lead to leaks or failure, especially in areas with hard water or fluctuating temperatures.
For residential applications, EZP Plumbing exclusively uses Type L copper despite its slightly higher cost. Why? Because we believe that providing the best materials upfront not only ensures a longer-lasting plumbing system but also protects our customers from unexpected issues and additional costs down the road. Even though Type L copper may be a bit more expensive and take a little longer to work with, the benefits far outweigh the minor inconvenience.
Why EZP Plumbing Chooses Type L Copper for Residential Services
While many other residential plumbing companies may opt for the more cost-effective Type M copper, we believe in providing quality and longevity with every job. Here’s why EZP Plumbing sticks with Type L copper, even for residential services:
- Durability and Longevity: Type L copper is thicker and more durable, meaning it can withstand pressure fluctuations, temperature changes, and external impact far better than Type M. This results in a plumbing system that lasts longer, reducing the risk of premature leaks and costly repairs.
- Corrosion Resistance: Type L copper is less likely to corrode or develop pinhole leaks over time. This is especially important in areas with hard water or high levels of mineral buildup, which can cause pipes to degrade more quickly. Type M copper’s thinner walls make it more prone to deterioration.
- Better for High-Pressure Applications: In any plumbing system, it’s crucial that pipes can handle fluctuating pressure without bursting or failing. Type L copper’s thicker walls give it a higher pressure rating than Type M, making it a more reliable option for homes with multiple bathrooms, large water fixtures, or other high-demand systems.
- Fewer Future Repairs: While Type M copper may cost less upfront, the potential for needing to replace damaged or leaking pipes in the future can quickly outweigh any initial savings. With Type L copper, you’re investing in a plumbing system that will require fewer repairs and replacements over its lifetime, saving you money and hassle in the long run.
- Peace of Mind: At EZP Plumbing, we believe in doing the job right the first time. By using Type L copper, we provide our customers with the peace of mind that their plumbing system is built to last, no matter what. We want our clients to be confident that their pipes won’t fail after a few years, which is why we use the highest-quality materials available.
A Small Investment for Big Returns
Yes, Type L copper is slightly more expensive and requires a bit more time to work with, but this small investment pays off over time. The longer lifespan, superior strength, and resistance to damage mean fewer plumbing issues down the road. At EZP Plumbing, we prioritize the long-term satisfaction of our customers, and that’s why we’re committed to using the best materials—even for residential plumbing projects.
Final Thoughts
When choosing the right copper for your plumbing system, it’s important to consider both the immediate cost and the long-term benefits. While Type M copper may be suitable for some situations, Type L copper offers greater durability, longevity, and protection for your home. By choosing Type L, you’re investing in a plumbing system that’s built to stand the test of time.
