## Overview

The NDS 420C Pop-Up Drainage Emitter is a durable, polyethylene-covered drainage solution designed to fit 3-inch and 4-inch sewer and drain fittings. It efficiently releases up to 40 gallons per minute of collected stormwater runoff, protecting properties from water damage by directing flow to safe discharge areas. Its innovative pop-up cap opens only under water pressure, preventing debris intrusion and reducing trip hazards with a low-profile design. Built to support pedestrian and lawn tractor traffic, it offers easy installation and is backed by a limited lifetime warranty for dependable, long-term use.

## Description

Take stormwater runoff captured by grates, catch basins, channel drains, and other drainage systems to drain pipe, and carry it to a point of release downstream to discharge with a Pop-Up Drainage Emitter. The Pop-Up Drainage Emitter connects to 3 in. and 4 in. sewer and drain fittings which connect to sewer and drain pipe and triple-wall pipe. Cover is made of polyethylene.

Review: Perfect Solution for Lawn Drainage – Easy Install & Works Flawlessly! - I recently installed the Pop-Up Drainage Emitter as part of my yard's drainage system, and I couldn't be happier with the results. It’s incredibly easy to install and fits perfectly with standard 4-inch drain pipes. The pop-up top works just as advertised—only opens when there’s water flow, keeping debris and critters out when not in use. What I really appreciate is the low-profile design. It blends in nicely with the lawn and doesn’t get in the way of mowing or foot traffic. Even after several heavy rainstorms, the emitter has performed flawlessly, preventing any pooling or flooding in problem areas. If you’re looking for a simple, effective, and durable solution for lawn drainage, this is it. Highly recommended!
Review: Great drain emitter! - 2nd time I have purchased this pop up drain emitter (for a different drain), Fits nice and snug and works great. Highly recommend!

## Features

- Works with a complete drainage system to release collected stormwater runoff and standing water to a discharge point before it causes costly property damage. Provides collected water a point of release at water-safe areas downstream and away from structures, erosion-prone landscapes, and poor drainage areas
- Connects to 3 in. & 4 in. sewer and drain fittings; connects to other pipe types using appropriate adapters. Releases collected water up to 40 GPM. Supports pedestrian traffic including lawn tractors, when properly installed
- Outside flange prevents grass from growing over the cover
- Cap, or cover, pops up as high as 1 in. once water pressure builds; closes as flow diminishes. Flat profile design reduces trip hazard posed by open drain; closed position keeps emitter flush to the ground and safe from lawn mower blades
- Comes with one Pop-Up Drainage Emitter . Hassle-free limited lifetime warranty guarantees the NDS product is free from defects—or we’ll replace it

## Questions & Answers

**Q: Why do you describe this as 3 inch and 4 inch?   one answer suggests it's 4 inch not 3 inch... so isn't your description wrong?  certainly unclear.**
A: The pop up head fits into a 4" PVC SDR35 fitting or over a 3" PVC SDR35 fitting

**Q: The pipe we have is 3 3/8 inches o.d.  The emitter fits over it, but not snugly.  Can anyone tell me what kind of adapter to use?**
A: Just use a screw(stainless to prevent rust). Drill a small hole threw the pipe and emitter rim and secure the emitter to the pipe.  Common fix.

**Q: For anyone that has used the popup valve, do you get soil erosion around the popup valve?  I'm going to be using this with a sump pump.**
A: I've had mine for one year. It discharges an underground drainpipe leading from an upgradient catch basin that drains what used to be a waterlogged low area next to my house. I see no erosion by the popup, which is on a hillslope barely above the soil surface where a grassy lawn grows. It looks just like the rest of the lawn.

**Q: Does it come in gray or white color?**
A: Gray or white ???? I don't know for sure.  Mine are a dark forest green.  I never seen anything to indicate there are any color choices. Does not seem likely but again I cannot say for sure.  Try looking on internet for manufacturer web site.  If green is undesirable I suppose some spray paint might be appropriate.
