Dfnidy Pop Up Drain Emitter Cap | 4-Inch Replacement for 420C/422G Drainage System

Overview

The Dfnidy Pop Up Drain Emitter Cap is a weather-ready upgrade designed for 4-inch sewer and drain fittings. It integrates with NDS 420C pop-up drainage emitters and serves as a practical addition to yard, lawn, and courtyard drainage setups. Rather than simply covering a pipe, this cap supports a complete drainage system that helps manage stormwater with a clean, low-profile presence.

Key benefits

• Efficient drainage capacity: engineered to handle up to 40 GPM, it opens under water pressure to release flow and closes when pressure drops, helping minimize debris buildup during calmer periods.
• Smart exterior design: the green, flat profile reduces the risk of mower contact and keeps grass from easily obstructing the emitter, maintaining steady drainage.
• Durable construction: made from polyethylene, it withstands lawn traffic, pedestrian use, and harsh weather, contributing to a longer service life.

Compatibility and installation

• Compatibility: replacement for NDS 420C pop-up emitters and suitable for 4-inch courtyard or lawn sewer and drain fittings; supports a complete drainage system including catch basins and channel drains.
• Installation options: connects to a 4-inch sewer drain pipe or a three-wall pipe; with adapters, it can be attached to other piping configurations.
• Ground-level integration: install flush with or slightly below ground level to reduce bumps and enhance durability of the outdoor drain cover.

Durability and outdoor performance

Constructed to resist lawn mower blades and foot traffic, the Dfnidy emitter cap remains reliable through seasonal sun exposure and varying weather, helping you maintain consistent drainage without frequent replacements.
