Answer This Question

Hi Marie, 4in. Corrugated pipe and flexible drainage pipe can be attached to the Storm Drain Inline basin by connecting the RELN 4in. Corrugated pipe adapter to the end outlet https://www.homedepot.com/p/RELN-4-in-Corrugated-Pipe-Adapter-000225/304163129 The smooth end of the adapter can be solvent welded to the Inline basin end outlet (recommend using the RELN sealant https://www.homedepot.com/p/RELN-2-8-oz-Silicone-Superior-Watertight-Drainage-Sealant-Black-000309/316357755) and the ribbed end is a snap connection into your corrugated pipe. For more information, please feel free to call our toll-free helpline @ 1-855-215-6858
