Advanced Drainage Systems 422 Aa 4 in Hdpe Snap Wye

Product Description

The ADVANCED DRAINAGE SYSTEMS 422 AA is a 4-inch single-wall corrugated HDPE snap wye fitting designed for drainage pipe installations. This fitting allows a branch line to tie into a main drainage run at a wye angle, creating a smooth flow transition. The snap-fit design speeds up assembly without requiring adhesives or separate couplings. Made from high-density polyethylene (HDPE), the fitting resists corrosion and handles the moisture and soil conditions typical of subsurface drainage applications. Licensed plumbers and drainage contractors are the primary installers.

This snap wye is suited for residential and light commercial drainage systems using 4-inch single-wall corrugated pipe. Common applications include foundation drainage, yard drainage, French drain tie-ins, and agricultural runoff management. The snap connection integrates directly with compatible corrugated pipe, making it a practical choice for field installations where speed and simplicity matter.

Key Features

• 4-inch diameter fits standard single-wall corrugated HDPE drainage pipe
• Snap-fit connection requires no adhesives or extra couplings
• HDPE construction resists corrosion, chemicals, and moisture
• Wye configuration allows branch line tie-ins with smooth flow transition
• Corrugated profile maintains flexibility for field routing

Compatibility

Designed as an OEM-style fitting for use with 4-inch single-wall corrugated HDPE drainage pipe systems in residential and light commercial drainage applications.

Installation Notes

Installation is typically performed by licensed plumbers or drainage contractors following local plumbing and grading codes. Before beginning work, relieve any standing water and confirm the trench is stable. The snap connection should be fully seated by hand until it locks; do not use hammers or excessive force on the fitting body. Verify proper slope and flow direction before backfilling.
