The ADVANCED DRAINAGE SYSTEMS 0321AA is a 3-inch snap tee fitting designed for use in corrugated drainage pipe systems. The snap-fit connection style allows for fast, tool-free assembly in the field, reducing labor time during drainage installation. This fitting is typically installed by plumbers, landscapers, and site contractors working on stormwater management, foundation drainage, or subsurface irrigation systems. The 0321AA is sold in a package quantity of 12 units, making it practical for larger drainage runs requiring multiple branch connections.
This snap tee is suited for residential and light commercial drainage applications where corrugated pipe tees are needed to branch flow from a main line. Common install scenarios include French drain systems, downspout drainage, yard drainage, and perimeter foundation drain tile. The fitting is designed for use with corrugated flexible pipe and is well suited to below-grade installations in both landscape and construction drainage contexts.
Designed as an OEM-style replacement and standard fitting for 3-inch corrugated drainage pipe systems used in residential and light commercial stormwater and subsurface drainage applications.
Installation is typically performed by plumbers, drainage contractors, or experienced landscapers following local plumbing and site drainage codes. Ensure the main drainage pipe run is depressurized and free of flow before making branch connections. The snap-fit design requires proper pipe seating to achieve a secure connection — confirm the fitting is fully engaged before backfilling. Follow local IPC or municipal stormwater guidelines for burial depth and pipe slope requirements.
