Effective, but a bit expensive

- Reviewed in Canada on June 5, 2025Verified PurchasePops up easily. This design allows for a few leaves to come out when raining. I don't have a lot of large trees so I don't know how it would handle that situation. I am able to remove it during the winter season so it wont freeze shut. Overall, a good product.
- Reviewed in Canada on September 20, 2024Verified PurchaseOrdered for my dad who ruined his with the lawnmower. This was perfect fit and he was very happy to get it so quickly
- Reviewed in Canada on October 7, 2023Verified PurchaseToo costly! I used it to bury 4” drainage tile to keep downspout water away from my house.

Reviewed in Canada on April 17, 2023Verified PurchasePour remplacer un qui s'est brisé qui avait été installé par un contracteur. Celui-ci a un plus grande superficie que l'ancien mais sincère parfaitement sur le tuyeau de 4 pouces en PVC.
- Reviewed in Canada on November 18, 2020Verified PurchaseTrenched and placed 15' of 4" PCV out into yard getting the downspout flow away from the foundation. The pop-up emitter works great to release the rain water. Heavy rain areas might need longer length drain pipes. Make sure you have a slight decline in the pipe for flow (check with a plumber). Make sure the the emitter is low enough so lawnmower won't hit. Would buy again.

5.0 out of 5 stars Perfect Solution for Lawn Drainage – Easy Install & Works Flawlessly!
Verified PurchaseI 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!

5.0 out of 5 stars Perfect Solution for Yard Drainage Issues
Verified PurchaseI just gotta say, this NDS 420C Pop-Up Drainage Emitter is an absolute game-changer for anyone dealing with yard drainage problems. It's like magic how it works with those 3-inch and 4-inch drain fittings! I love how it fits perfectly into drainage systems with catch basins. The green plastic design blends right in with the lawn, so it's not an eyesore. Trust me, if you're looking for a seamless solution to your drainage woes, this is it. Highly recommend it!

4.0 out of 5 stars Working Well!
Verified PurchasePlastic seems of good quality and durable. Easy to pop in the gutter pipe leading away from house. So far it is working effectively and doing a great job of popping up and letting the rain water escape from gutters. Be very careful when using a lawn mower around the emitter because this is the third time I have replaced this same area emitter. I have a tendency to forget and hit emitter with lawn mower tire and break off an edge or two because the emitter is sloping in the ground.
I do occasionally pop off the emitter and clean out the trash, leaves and muck still in pipe. Time will tell how long this emitter will last. I think these are priced expensively, however, what isn't expensive these days?

5.0 out of 5 stars Perfect Fit!
Verified PurchaseItem arrived exactly as described. Popped off the broken drain and replaced it with this drain, it fit like a glove and was easy to install. Another small repair project completed without any issues. Looks great, sturdy, and appreciate the value for the money!
