## Overview

The National Diversified 422 4-Inch Pop-Up Drainage Emitter by NDS is a durable PVC drainage solution designed to efficiently manage water flow with a 4-inch internal diameter. Its pop-up design ensures it remains flush with your lawn, preventing mower interference while reducing erosion by directing water away from sensitive areas. Ideal for professional-grade landscape drainage, it combines functionality with low-maintenance durability.

## Description

Open and flow through water pressure drain pipe. Not high enough to raise the lawn mower. Reduces emitter and closed flow Internal Diameter: 4 in. Material: PVC Color: Green Pop-up release. Because of that, water is water safe construction, the area away from the erosion-prone landscape and lower drainage areas.

Review: Rain pushed the top valve out and it was down the street to a main city gutter. Not very stable.
Review: Took two hours to install two of these. Planted grass seed around then and over the corrugated pipe. I was very careful to not place them so that the tires of the rider mower would not go over the unit and potentially damage the pop up emitter. Since these do not have any springs on them to prevent them from popping up the suction of the mower pulled it up and chewed the pop up portion into about 10 pieces. Whole thing ruined! Unbelievable! I have purchased this item before but it had a spring installed so that the pop up portion would not come up too easily. I don't know if these are still available with springs loaded into the pop up portion but if they are I am going to try and find them and I would suggest you do the same. And since I bought them over 30 days ago and just now was able to install them I can't return the other one that hasn't been sucked into the stratosphere. Hope it doesn't happen. Extremely Disappointed.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by C***T on August 8, 2014*

Works like a charm. I went a bit further and actually built a dry-well, putting a 5' hole filled with rock under the emitter. Instead of the 90 degree elbow my emitter is installed on top of a 4" PVC T. I utilized the 90 at my downspout. My drainage now goes under my patio slab sidewalk. My hope is this takes me into colder weather to provide continued drainage below the frost, but I'm not certain how that will work in the dead of winter. Not much water flows in those months anyway. During heavy extended rainfall the pop-up just spills on the lawn anything my dry-well can't handle. Installed at ground level I can take the lawn mower right over it as advertised, worry free. I went to all the big hardware stores for any device like this and they looked at me like I had 2 heads. I found none of the chain stores in my area sold them or really knew what I was trying to build. No problem buying one here on Amazon though. So far, I'd recommend this device to anybody wanting to get rid of a troublesome downspout and drain sitting in a traffic area. A little work trenching, but no more tripping hazard.
