The FLEX-Drain 51710 Solid Drain Pipe is a premium, expandable drainage solution engineered for maximum flexibility, strength, and ease of installation. Designed to move water efficiently from one point to another, this 4-inch by 12-foot solid pipe is ideal for a wide range of residential and commercial drainage applications, including downspout runoff, foundation protection, and landscape water management.

Key Features:

• Expandable and Flexible Design:
  This pipe expands from a compact 21 inches to a full 12 feet, allowing it to bend around obstacles and conform to tight or irregular spaces without the need for additional fittings or elbows 

• Solid Wall Construction:
  Unlike perforated pipes, this solid version is designed to channel water without allowing infiltration, making it perfect for applications where you want to move water away from structures or sensitive areas without dispersing it into the surrounding soil 

• Durable No-Break Copolymer Material:
  Constructed from high-strength, UV-resistant polypropylene, the 51710 is built to withstand harsh environmental conditions and resist crushing, cracking, and corrosion. It meets the Corrugated Polyethylene Pipe Association’s standards for crush resistance

• Soil-Tight Snap-Lock Fittings:
  Integrated fittings are built into the pipe, creating a secure, soil-tight seal that eliminates the need for separate couplers or connectors. This simplifies installation and ensures a leak-resistant connection 

• Holds Shape After Bending:
  Once bent into position, the pipe retains its shape, making it ideal for custom routing in both above-ground and underground installations
