Avanhitch 4-inch Pop Up Drainage Emitter with Elbow – Direct Fit for 4-inch PVC D2729, SCH40, SDR35

Overview

Meet the Avanhitch 4-inch pop up drainage emitter with elbow, engineered to integrate with popular outdoor piping without the need for extra adapters. A low-profile top helps keep lawns usable and reduces mower contact after rain, while the integrated elbow redirects flow away from foundations and low spots.

Direct-fit compatibility

This unit is designed to directly connect to common 4-inch piping and compatible 3–4 inch corrugated options, across standard fittings. The stepped shoulders and locking geometry support proper seating and alignment across multiple pipe types, making installation straightforward in many backyard drainage layouts.

• Directly fits 4" PVC D2729 S&D, 4" Schedule 40, 4" SDR35
• Works with 3" to 4" corrugated pipe without adapters
• Not recommended for 3" triple-wall pipe for guaranteed fitment

Smart dual-rod pop up and elbow design

The dual-rod guide minimizes tilt and keeps the lid level during operation. A spring-free design avoids common corrosion and binding, helping maintain smooth movement over time. The integrated elbow directs waterflow away from foundations, walls, and other structures in your yard.

Low-profile top and practical drainage use

The top sits flush or near flush with the lawn, reducing mower contact and keeping landscape work zones accessible after heavy rain. The textured surface resists scuffs, helping the emitter stay visually unobtrusive in outdoor spaces.

Where it fits into your drainage system

Designed for use at the downstream outlet of underground drainage lines, including downspouts, channel drains, catch basins, and yard drain networks. This emitter complements typical residential outdoor drainage layouts for steady water management.

Size tips

Size selection matters for proper fit. If your 3-inch pipe connects inside a 4-inch fitting, choose the 4-inch version. If your drainage uses only 3-inch pipe with no 4-inch fittings, select the 3-inch variant from the product family.
