Type K copper pipe is commonly used for water distribution.
Here's a breakdown of why Type K is suitable and some additional information about copper pipes used for water:
Types of Copper Pipes Used for Water Lines:
While Type K is a common choice, other types of copper pipe are also used, depending on the application and local codes. It's crucial to consult local plumbing codes and a qualified plumber before selecting a specific type.
-
Type K Copper Pipe: This has the thickest wall of all common copper pipe types. Its durability makes it suitable for underground water mains, water distribution, fire protection, and HVAC systems. Available in both rigid and flexible forms. It can be used with flared and compression fittings.
-
Type L Copper Pipe: This is a mid-grade option with thinner walls than Type K. Type L is typically used for interior plumbing, water distribution, and some HVAC applications. It is less expensive than Type K but still offers good corrosion resistance and durability.
-
Type M Copper Pipe: This has the thinnest walls and is generally used for residential water distribution systems. It is the least expensive of the three types but is also the least durable. Type M is typically not allowed for underground applications.
Factors to Consider When Choosing Copper Pipe:
- Water Pressure: Higher water pressure requires thicker-walled pipes (Type K or L).
- Location: Underground applications often require Type K due to its durability.
- Code Requirements: Local plumbing codes dictate which types of copper pipe are permitted in specific applications.
- Cost: Type M is the least expensive, followed by Type L, and then Type K.
- Corrosion Resistance: All types of copper are relatively resistant to corrosion, but soil conditions might dictate the need for extra protection.
Why Copper Is a Good Choice for Water Pipes:
- Durability: Copper pipes can last for many years with proper installation.
- Corrosion Resistance: Copper is naturally resistant to corrosion.
- Antimicrobial Properties: Copper inhibits the growth of bacteria.
- Recyclability: Copper is a recyclable material.
Important Note: Always consult a qualified plumber to determine the best type of copper pipe for your specific application and to ensure proper installation that complies with local codes.
