2 Pack Compatible replacement for 420C: Pop-up drain emitter cap designed as a replacement compatible with 420C pop-up drainage emitter. Fits standard 3-inch and 4-inch sewer and drain pipe connections when installed with appropriate fittings.
Automatic pop-up operation: Cap rises up to approx. 1 inch when water pressure builds and closes automatically as flow decreases, allowing collected water to discharge while keeping the outlet closed when not in use.
Reinforced structure design: Emitter cap features approximately 20% added material reinforcement at key stress areas to support improved structural stability during repeated opening and closing cycles.
Flush, low-profile design: Flat, ground-level profile stays flush when closed, helping reduce interference with lawn maintenance equipment and pedestrian traffic when properly installed.
Drainage system application: Works as part of a complete drainage system to guide collected runoff toward designated discharge areas away from foundations, low-lying zones, and drainage-challenged locations.
