Amerimax 51510 Drain Pipe Tubing with Socket, 4 in, PVC, Black, 25 ft L Black

Exceeds ASTM standards and is made with no-break copolymers for professional-grade strength and integrity. Proprietary peak and valley design offers greater surface area and a 30% higher load-bearing rating than standard corrugated pipe. Perforated pipe with sock is ideal for French drain application in fine soil. Fittings available to adapt to 3 or 4 in, corrugated pipe and 4 in PVC. Ideal for tight spaces and curvy places, taping joints is not necessary. This pipe has spaced slits, so water drains in stages. It's also ideal for applications such as French drains or dispersing water from flower beds, but works even better in locations where surrounding soil or sand is fine and requires filtration or where debris is considerable.
