NDS 420C Pop-Up Drainage Emitter, fits 3-Inch and 4-Inch Sewer and Drain Fittings, Works with Drainage Systems Including Catch Basins and Channel Drains, Green

Perfect replacement cap for our broken piece. Top is A bit larger overall, but for the pipe/drain perfectly. Easy to install & already worked well in storm.

Great price. Shipping was a little slow but I wasn’t in a hurry. Fit in a 4” pipe perfectly. I added two set screws to keep it secure. No spring on the poppet but it retracts fine, and my riding mower doesn’t lift and cut this one. I will buy again. Says it’s made in the USA.

Great product and easy to install

Plastic 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?

My husband wanted to go to Lowe’s for a replacement because ours was cracked. I checked Amazon and the exact item was $3.00 less. Fits and works perfectly.

The NDS 420C Pop-Up Drain Emitter works perfectly with my 4-inch drain pipes! It’s durable, easy to install, and effectively prevents clogs. The green plastic blends well with landscaping. Great for catch basins and yard drainage—no more standing water. Highly recommend for reliable, low-maintenance water flow control. A must-have for drainage systems!

Simple yet effective! Redirects runoff without mower snags.

Perfect Fit!! Better than the original one installed!
