Did You Know?
1. Did you know that Type M copper pipe is commonly used in residential plumbing systems? This versatile copper pipe is often used for both hot and cold water distribution, as well as for drainage and waste systems.
2. Unlike other types of copper pipes, Type M copper pipe has the thinnest wall thickness. This makes it more flexible and affordable, making it a cost-effective option for plumbing installations in houses and apartments.
3. Type M copper pipe is also commonly used for underground water service lines. Its durability and resistance to corrosion make it an ideal choice for these applications, as it can withstand the natural elements and last for many years.
4. If you’ve ever seen a home with a baseboard heating system, chances are it was installed using Type M copper pipe. The pipe’s high heat conductivity allows it to efficiently carry hot water from the heating source, distributing warmth throughout the space.
5. Type M copper pipe can also be used for gas distribution, although it is not as common as other materials, such as steel or plastic. Its corrosion resistance and durability make it a safer option for gas lines, ensuring the integrity of the system.
Types Of Copper Pipe Used In Construction
Copper pipes play a crucial role in the construction industry, serving various purposes such as water supply lines and refrigerant lines in HVAC systems. In both residential and commercial construction, three predominant types of copper pipes are utilized: Type K, Type L, and Type M. These types vary in terms of wall thickness and are specifically designed for different applications.
Common Applications Of Type K Copper Pipe
Type K copper pipe is widely used in various applications due to its thick wall, durability, and strength. It is specifically recommended for main water lines and underground installations, where its sturdy construction ensures the safety and reliability of the plumbing system. Additionally, Type K copper pipe finds application in fire protection, oil, and HVAC systems.
Some key features of Type K copper pipe include:
- Thick wall for enhanced durability
- Suitable for high-pressure systems
- Ideal for underground installations
- Reliable performance in water distribution
- Versatile for use in multiple applications
In summary, Type K copper pipe offers a reliable solution for various plumbing needs, providing long-lasting performance and peace of mind.
Characteristics And Applications Of Type L Copper Pipe
Type L copper pipe is the most commonly used copper piping in residential and commercial plumbing. It has a slightly thinner wall compared to Type K. It is suitable for a wide range of applications, including interior plumbing, fire protection, and some HVAC systems. Type L copper pipe offers a good balance between durability and cost-effectiveness, making it popular in the construction industry.
- Type L pipe is widely used in residential and commercial plumbing
- It is suitable for interior plumbing, fire protection, and some HVAC systems
- Type L copper pipe has a slightly thinner wall compared to Type K
- It offers a good balance between durability and cost-effectiveness
Advantages And Uses Of Type M Copper Pipe
Type M copper pipe is a popular choice for residential work due to its cost-effectiveness. It has a thinner wall compared to Type K and Type L, but is still a reliable option for above-ground applications. This type of pipe is commonly used for domestic water service and vacuum systems, making it suitable for plumbing drains and vents in older homes. However, it is worth mentioning that Type M copper pipe has been increasingly replaced by PVC or ABS plastic pipe in modern construction.
Considerations And Limitations Of Type M Copper Pipe
One key aspect to consider when using Type M copper pipe is its low-pressure rating. It can withstand pressures ranging from 10 to 15 psi which is significantly lower than the water pressure in most municipal water supply systems.
Therefore, Type M copper pipe may not be suitable for certain high-pressure applications and may not be approved by plumbing codes in all areas. It is important to consult local regulations and guidelines to ensure compliance with the plumbing codes when considering the use of Type M copper pipe.
Additionally, Type K copper pipe is not approved for use in natural gas applications, so alternative pipes must be used for those purposes.
- Consider the low-pressure rating of Type M copper pipe (10 to 15 psi)
- Not suitable for high-pressure applications
- Check local regulations and plumbing codes for approval
- Type K copper pipe is not for natural gas applications

Frequently Asked Questions
Should I use Type L or Type M copper pipe?
When deciding between Type L or Type M copper pipe for your project, it is crucial to consider the intended application and local codes. Type L, being a medium weight option, is commonly used in residential water lines. It offers durability and reliability suitable for most home plumbing systems. On the other hand, Type M, being thinner, is typically employed underground or for light domestic water lines, provided it aligns with the local codes and regulations. Always remember to check your state and local codes before commencing any project to ensure compliance with safety standards and regulations.
Where is Type K copper pipe used?
Type K copper pipe is commonly used in various applications that require high pressure tolerance. One such application is large-scale water supplies, where the durability and strength of Type K copper pipes ensure long-lasting performance. Additionally, these pipes are suitable for compressed air pipes, ensuring efficient and reliable transportation of air in industrial settings. They are also commonly used in fire protection systems, providing a trustworthy conduit for delivering water in emergency situations. Furthermore, Type K copper pipes find significant usage in heating and cooling systems, where their corrosion resistance and longevity make them an ideal choice. Finally, industrial conduits benefit from the use of Type K copper pipes, as they provide a reliable means of transporting various substances within industrial environments.
What is Type G copper pipe used for?
Type G copper pipe is specifically designed and used for above-ground natural gas and propane supply. It is manufactured to meet the ASTM B837 Type G specifications, ensuring its suitability and safety for such applications. This type of copper tubing provides a reliable and durable solution for delivering natural gas and propane to residential and commercial buildings, where above-ground installations are required. Its composition and design make it resistant to corrosion and suitable for the pressure requirements of gas supply systems.
Can Type M copper be used for pressure?
While Type M copper may have a maximum pressure rating of 701 pounds per square inch at 100 degrees, it is not suitable for pressure applications due to its annealed state, which reduces its maximum pressure rating to only 337 pounds per square inch. Thus, Type M copper is better suited for non-pressure applications where its strength is not a critical factor. If pressure is a concern, it is advisable to opt for a different type of copper pipe with a higher pressure rating.
