Yes, copper pipe can be installed underground, but with necessary precautions.
Considerations for Underground Copper Pipe Installation
While copper is a durable material, it can be susceptible to corrosion when buried underground. Therefore, proper installation methods are crucial to ensure longevity and prevent issues. Here's a breakdown:
Protection is Key
- Wrapping or Sleeving: According to the provided reference, wrapping the copper pipes before burying them provides a protective layer. This helps to shield the copper from direct contact with potentially corrosive soil.
- Aggressive Soil Conditions: Sleeving or wrapping is particularly important when the soil is considered "aggressive." This means the soil has characteristics that could promote corrosion.
- Proper Application: The reference also notes that improper sleeving or wrapping can cause more harm than good. Therefore, it's vital to follow best practices for material selection and application. Only use these techniques when necessary.
Other Factors
- Soil Type: Different soil types have varying levels of corrosiveness. Factors like acidity and moisture content play a significant role.
- Depth of Burial: The depth at which the pipe is buried can also affect its exposure to environmental factors.
- Local Codes: It's important to consult local plumbing codes and regulations, as these can dictate acceptable practices and materials for underground installations.
Best Practices Summary
| Aspect | Recommendation |
|---|---|
| Protection | Wrap or sleeve the pipe, especially in aggressive soil conditions. |
| Application | Follow proper installation techniques; avoid improper wrapping or sleeving. |
| Soil Type | Assess soil corrosiveness; adjust protection methods accordingly. |
| Regulations | Adhere to all relevant local plumbing codes and regulations. |
| Depth | Bury at an appropriate depth to minimize exposure to environmental factors, considering local regulations. |
By taking these precautions, copper pipe can be safely and effectively used for underground applications.
