NDS 420C Pop-Up Drainage Emitter, 3-Inch and 4-Inch

1) This product provides great value for your money. It helps so much with yard drainage and costs very little.2) It's so durable. I've been monitoring it for about 3.5 years now, and it has withstood all the sun, heat, and thunderstorms nature has thrown at it. Also, it has never caught the blade of my lawn mower, which has probably passed over it around 100 times now.3) The rounded interior contours, internal ribs, and high-density polyethylene (HDPE) construction contribute to the overall strength of the product.4) It's so simple to install if you've done your measurements in advance.5) Cleaning the product is easy, although I've almost never had to over the years. But it's just as effortless to remove this product from the pipe as you might expect for something that stays embedded in your lawn all year long.6) The emitter pops up just like it's supposed to during heavy storms that cause copious drainage. When installed properly, this product performs extremely well.

Received promptly and in good condition. Easy to install and functions well. Used to divert eaves rainwater to a garden bed affixed to the end of a buried drain pipe. Recommended.

Fit perfectly, good quality replacement item.

Fit my system and has lasted

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!
