## Overview

The NDS 420C Pop-Up Drainage Emitter is a durable polyethylene device designed to connect with 3- and 4-inch drain pipes, automatically releasing stormwater runoff to safe discharge points. Activated by hydrostatic pressure, it prevents erosion and protects structures by efficiently managing water flow from grates, catch basins, and gutter systems.

## 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.

## 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.
