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

Description

💧 Keep your property dry and damage-free with smart drainage that works when you need it most!

The NDS 420C Pop-Up Drainage Emitter is a durable polyethylene device designed to divert stormwater from drainage systems through 3- and 4-inch pipes. It opens automatically under hydrostatic pressure to release water safely away from structures and erosion-prone areas, then closes as flow diminishes, ensuring efficient and protective drainage management.
