The FLEX-Drain 51510 Solid Drain Pipe is a premium, expandable drainage solution engineered for maximum flexibility, strength, and ease of installation. Designed to efficiently move water from one point to another, this 4-inch by 25-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 form to a full 25 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 51510 is built to withstand harsh environmental conditions and resist crushing, cracking, and corrosion. It meets or exceeds ASTM standards for underground use 

• 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 during backfilling

• 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.
