DWC (Double Wall Corrugated) pipes and fittings are high-performance underground piping solutions widely used for drainage, sewerage, and cable ducting. Manufactured from HDPE material, these pipes feature a corrugated outer wall for strength and a smooth inner wall for efficient flow. DWC (Drip Irrigation with Gravity) is a method of hydroponic gardening where water is delivered to plants through a series of drip emitters, without the use of a pump. The system uses gravity to flow water from a higher point to a lower point, and the emitters control the amount of water delivered to each plant. DWC fittings are a vital component of this system, as they connect the various components and ensure proper flow of water. The most common type of DWC fitting is the staple, which attaches the drip line to the PVC tube and the tubing to the water supply line. Other types of DWC fittings include ball valves, connectors
