The Amerimax 51110 FLEX-Drain Solid Pipe is a high-performance, expandable drainage solution engineered for strength, flexibility, and ease of installation. Designed to move water efficiently from one point to another without infiltration, 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 6 feet 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:
  The non-perforated design ensures that water is directed exactly where you want it—perfect for applications where water needs to be carried away from structures or sensitive areas without seeping into the surrounding soil 

• Durable No-Break Copolymer Material:
  Constructed from high-strength, UV-resistant polypropylene, the 51110 is built to withstand harsh environmental conditions. It meets the Corrugated Polyethylene Pipe Association’s standards for crush resistance, ensuring long-term durability 

• 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.
