Nds 420C 4 Inch Pop-up Emitter Replacement Lid Green

Product Description

The NDS 420C is a replacement lid for 4 inch pop-up emitters used in residential and commercial landscape drainage systems. The lid snaps onto existing emitter bodies to restore proper function without replacing the full assembly. It is designed to remain closed during dry conditions, blocking debris, insects, and rodents from entering the drain line. When water flow builds sufficient pressure, the lid opens to release runoff and then reseals automatically. Licensed landscapers, irrigation contractors, and drainage installers typically handle this component as part of routine maintenance or storm drain service work.

This replacement lid is suited for surface drainage applications where maintaining a low profile is important. The green color blends into turf and groundcover, making it visually unobtrusive in lawn and garden settings. Because the lid does not rise high enough to interfere with mowing equipment, it is a practical choice for installations in maintained lawn areas. It fits 3 inch and 4 inch hub sewer and drain fittings, making it compatible across a range of standard drainage assemblies.

Installation Notes

Installation does not typically require special tools. Ensure the existing emitter body is clean and free of debris before seating the replacement lid. No power shutoff is required for this fitting, but confirm the drainage line is not under active flow before servicing. Follow applicable local plumbing and drainage codes when working on below-grade storm or sewer drainage systems.
