## Overview

The NDS 420C Pop-Up Drainage Emitter is a smart, durable drainage solution designed to divert stormwater safely away from vulnerable areas. Compatible with standard 3- and 4-inch pipes, it uses hydrostatic pressure to open only when water flows, preventing debris entry and ensuring efficient drainage. Its low-profile polyethylene cover blends seamlessly into your landscape, making it an easy-to-install, reliable choice for flood prevention and erosion control.

## 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: So easy to install and works fantastic. Just make sure you use perforated pipe or drill hole in elbow going up to prevent freezing in winter.
Review: 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!

## Features

- Allows water to be diverted and released to water-safe areas away from structures, erosion-prone landscapes and poor drainage areas
- Allows water captured by grates, catch basins, channel drains and gutter systems to flow through drainage pipe
- Opens by hydrostatic pressure of water flowing through the drain pipe, as flow diminishes the emitter closes

## 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.
