Diy outdoor pex plumbing: can you do it yourself? find out here

PEX (cross-linked polyethylene) pipes have revolutionized the plumbing industry with their versatility and durability. However, when it comes to outdoor installations, the question of whether PEX pipe can withstand the elements arises. This comprehensive guide will delve into the intricacies of installing PEX pipe outside, providing you with the knowledge to make an informed decision.

Understanding PEX Pipe

PEX pipe is a flexible, lightweight, and corrosion-resistant piping material. Unlike traditional copper or galvanized steel pipes, PEX pipe is not susceptible to rust or scale buildup, making it an ideal choice for long-lasting installations.

Can You Install PEX Pipe Outside?

The answer is a resounding yes! PEX pipe can be installed outdoors, but certain precautions must be taken to ensure its longevity and performance.

Considerations for Outdoor PEX Pipe Installation

UV Resistance

PEX pipe is not UV-resistant, meaning prolonged exposure to sunlight can damage the material. To prevent degradation, it’s crucial to protect PEX pipes from direct sunlight by burying them underground or encasing them in protective sleeves.

Temperature Fluctuations

PEX pipe can withstand temperature variations between -40°F and 200°F. However, extreme cold can cause the pipe to freeze and burst. In areas with sub-freezing temperatures, consider adding insulation or heat tape to prevent freezing.

Pressure Limitations

PEX pipe is rated for different pressure capacities. For outdoor installations, it’s recommended to use PEX pipe rated for higher pressures to withstand the demands of water flow and potential pressure fluctuations.

Joint Integrity

Properly joining PEX pipe is essential for a leak-free installation. Use crimp rings or expansion fittings specifically designed for PEX pipe and follow the manufacturer’s instructions meticulously.

Proper Burial Depth

When burying PEX pipe underground, ensure it’s buried at the appropriate depth to prevent freezing or damage from heavy machinery. Generally, a depth of at least 12 inches is recommended.

Benefits of Installing PEX Pipe Outside

• Durability: PEX pipe is highly durable and resistant to corrosion, rust, and scale buildup.
• Flexibility: Its flexibility makes it easy to maneuver and install in tight spaces or around obstacles.
• Cost-effective: Compared to traditional piping materials, PEX pipe is more affordable and requires less labor for installation.
• Long lifespan: With proper installation and maintenance, PEX pipe can last for decades.

Applications of Outdoor PEX Pipe

• Irrigation systems
• Landscape lighting
• Outdoor faucets
• Pool and spa plumbing
• Underground water lines

Final Thoughts: Embracing the Versatility of PEX Pipe Outdoors

Installing PEX pipe outside is a viable option with proper planning and precautions. By understanding the considerations and following the recommended practices, you can leverage the benefits of PEX pipe for your outdoor plumbing needs.
