## Overview

The NDS 422G 4" Pop-Up Drainage Emitter with Elbow is a durable, high-density polyethylene drainage solution designed to discharge water efficiently from 4-inch pipes. Its innovative pop-up cap opens automatically under water pressure to release flow and closes to prevent debris intrusion. The elbow connector fits standard sewer and drain pipes, while a built-in weep hole ensures freeze protection. Ideal for protecting properties from water damage, it installs flush with turf to minimize lawn mower interference and blends discreetly into outdoor landscapes.

## Description

Every drainage system needs a point of release to prevent back-up issues. Use the Pop-Up Drainage Emitter to discharge water away from structures, erosion-prone landscapes, and poor drainage areas. The Pop-Up Drainage Emitter with Elbow connects to 4 in. sewer and drain pipe, and the cover “pops up” to release water when pressure builds. Cover closes once flow diminishes and stays closed when not in use to prevent debris & rodents from entering and potentially clogging the drainage system. Weep hole at bottom of elbow drains out water left in pipes to prevent stagnation or freezing in cold weather. Flat profile design blends discreetly into the surrounding landscape. Cover is made of polyethylene; elbow is made of polyvinyl chloride.Pop-Up Drainage Emitters are a part of a complete drainage system that help with stormwater management. They work with pipes, catch basin drains, channel drains, trench drains, and drain grates to filter, capture, and convey excess water to drain pipes; the pipes carry the water downstream to discharge with a Pop-Up Emitter, or to percolate into the ground with a dry well or infiltration trench.Find the right drainage solution for your needs with our NDS Home Drainage Center tool at ndspro.com/home-drainage. Founded in 1972, NDS is the leader in stormwater management solutions and the preferred choice of professionals, with proven products, tools, and expert support to help you get the job done right.

## Features

- RELEASE WATER AWAY FROM PROPERTY: Capture water upstream and carry it away from structures and poor drainage areas to discharge with the pop-up emitter positioned downstream
- HOW IT WORKS: The pop-up emitter works at a low point of the drainage system to discharge water collected from upstream and help protect property from water damage
- INSTALLATION: Elbow connects to 4 in. sewer and drain pipe and 4 in. triple-wall pipe, connects to other pipe types using appropriate adapters; install with cover flush or slightly below adjacent turf to reduce potential for clipping with lawnmower
- POPS UP TO OPEN, CLOSES WHEN FLOW DIMINISHES: Cap, or cover, lifts up as high as 1 in. once water pressure builds; flat profile design reduces trip hazard and is flush to the ground when properly installed
- ALL-WEATHER SAFE: Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather

## Questions & Answers

**Q: Do they freeze up?  I live in Wisconsin and worry the residual water may freeze.  Thanks**
A: I have 3 of these (similar buried systems) all running down angle underground  and yes they can freeze up  (residual water at/around the pop up, “Colorado clay” stops up the little relief drain hole) although just 1 of the lines seems to show drain water backup up to the downspout during melt…anyway, for winter I pull off the 4” at the bottom of the downspouts and slip on another adapter and length of 4” downhill” that is just open at the end (Maybe there’s a better way? because yes we have 4” laying on top of ground level that can trip over etc.!

**Q: How does the water make its way to the discharge with a hole in the bottom ?**
A: The hole in the bottom is so small that the vast majority the water will be emitted from the top. The hole only allows a small amount to drain, which is important after that heavy flow has stopped.

**Q: My down spout is rectangular is there a piece to connect with that shape on one end and circular on the other?**
A: Correct. There is a rectangular piece that fits on the downspout. Then you need your hose to connect to the drainage

**Q: Anybody use this in cold weather climates. Does it freeze up?**
A: No.  Have had 2 of then for several years in NY state.  Never a problem.  However they are used as an overflo for a drain pipe.  I have no idea what happens when they are under a foot of snow.  IBut f there is running water they won't freeze.
