When it comes to various plumbing and piping systems, burying tubing underground can be an advantageous option in certain situations. This practice is commonly used for irrigation systems, geothermal heating and cooling systems, or even for burying water lines. However, there are several considerations and guidelines to follow to ensure the tubing remains safe, functional, and compliant with regulations. In this article, we will explore the feasibility, benefits, and precautions associated with burying tubing underground.
Feasibility of Burying Tubing Underground:
The feasibility of burying tubing underground depends on various factors, such as the intended purpose, soil conditions, local regulations, and the type of tubing used. Common types of tubing used for underground installations include polyethylene (PEX), PVC, copper, and polyethylene (PE).
1. Intended Purpose:
Burying tubing underground is commonly done for irrigation systems, which require consistent water flow to plants or crops. Additionally, geothermal heating and cooling systems, known for their energy efficiency, often utilize underground tubing to exchange heat with the earth. Burying water lines for outdoor use, such as supplying water to barns, gardens, or pools, is another common application.
2. Soil Conditions:
The type of soil in the installation area is crucial when considering burying tubing underground. Certain soil compositions, such as sandy or loamy soils, allow for better drainage and are more suitable for underground installation. On the other hand, heavy clay soils can cause water accumulation and increase pressure on the tubing, potentially leading to damage.
3. Local Regulations:
Before proceeding with underground tubing installation, it is essential to consult local regulations. Different regions may have specific codes and standards that dictate the depth of burial, the type of tubing permitted, and requirements for marking the location of the buried tubing.
4. Tubing Types:
The choice of tubing is also a crucial consideration. PEX and PVC tubing are popular choices due to their flexibility and durability. Copper tubing is known for its resistance to corrosion and is commonly used for water lines. Polyethylene tubing (PE) is another suitable option, known for its resistance to various chemical substances and damage from sunlight exposure.
Benefits of Burying Tubing Underground:
Burying tubing underground offers several benefits, depending on the application and specific circumstances:
1. Protection:
Underground installation provides protection to the tubing from various external factors, including physical damage, weather conditions, and UV radiation. This helps maintain the integrity and longevity of the tubing, reducing the chances of leaks or failures.
2. Aesthetics:
Burying tubing underground helps conceal unsightly plumbing or irrigation systems, improving the visual appeal of the surrounding area. This can be particularly beneficial for residential properties or landscaped areas where maintaining a neat and clean appearance is desired.
3. Energy Efficiency:
In the case of geothermal heating and cooling systems, burying tubing underground allows for efficient heat exchange with the earth, promoting energy savings and reducing environmental impact.
Precautions and Guidelines for Burying Tubing Underground:
While burying tubing underground comes with advantages, there are essential precautions and guidelines to follow to ensure a successful installation:
1. Depth and Protection:
The depth of burial should comply with local regulations to prevent accidental damage caused by digging or other excavation activities. Additionally, it is crucial to protect the tubing with a suitable casing or sleeve to prevent damage caused by rocks, tree roots, or shifting soil.
2. Marking and Access:
To ensure future access and prevent damage from future construction or landscaping projects, it is important to mark the location of buried tubing and maintain accurate records or drawings. This will allow for easy identification and avoidance of the tubing during future excavations.
3. Insulation and Frost Protection:
In colder climates, proper insulation and frost protection measures should be implemented for buried tubing to prevent freezing. This may involve insulating the tubing, using heat tape, or burying the tubing below the frost line, which is the depth where soil is unlikely to freeze.
Burying tubing underground can be a suitable option for irrigation systems, geothermal heating and cooling, or burying water lines. However, feasibility, local regulations, and tubing type selection are crucial factors to consider. The benefits of underground installation include protection, aesthetics, and energy efficiency. By following the necessary precautions and guidelines, such as ensuring appropriate burial depth and protection, marking the tubing, and implementing insulation measures, underground tubing installations can be safe, reliable, and long-lasting.
