Understanding Direct Burial
Direct burial refers to the practice of installing pipes and fittings underground without the use of protective casings or conduits. This method is commonly employed in residential and commercial plumbing applications. When it comes to PEX fittings, direct burial is a viable option due to their inherent strength and resistance to corrosion.
Benefits of Direct Burial
Direct burying PEX fittings offers several advantages:
- Cost-effectiveness: Eliminates the need for expensive protective casings, saving on materials and labor costs.
- Simplicity: Direct burial simplifies the installation process, reducing the time and effort required.
- Durability: PEX fittings are designed to withstand the rigors of underground environments, ensuring long-lasting performance.
- Flexibility: PEX fittings can easily conform to the contours of the soil, reducing the risk of damage due to shifting or settling.
Types of PEX Fittings for Direct Burial
Not all PEX fittings are suitable for direct burial. The following types are specifically designed for this purpose:
- Crimp PEX Fittings: These fittings are secured using a crimping tool, creating a watertight seal.
- Expansion PEX Fittings: These fittings expand to fit the PEX pipe, providing a secure connection.
- Push-to-Connect PEX Fittings: These fittings simply push onto the PEX pipe, offering a quick and easy installation method.
Installation Guidelines
To ensure a successful direct burial PEX fitting installation, follow these guidelines:
- Choose the right fittings: Select fittings specifically designed for direct burial.
- Prepare the trench: Dig a trench that is deep enough to protect the fittings from freezing and damage.
- Lay the PEX pipe: Carefully lay the PEX pipe into the trench, ensuring it is free of kinks or bends.
- Connect the fittings: Join the PEX pipe to the fittings using the appropriate method (crimping, expanding, or pushing).
- Backfill the trench: Fill the trench with soil, compacting it to ensure stability.
- Test the system: Conduct a pressure test to ensure the system is watertight and functioning properly.
Precautions for Direct Burial
While direct burying PEX fittings offers many benefits, there are certain precautions to consider:
- Avoid sharp objects: Ensure the trench is free of sharp objects that could damage the fittings or pipe.
- Use caution with heavy equipment: When backfilling the trench, avoid using heavy equipment that could compact the soil excessively.
- Protect from freezing: In cold climates, bury the fittings deep enough to prevent freezing.
