Calvana (2 Pack) Pop-Up Drain Emitter, Cap Replacement for 420C Pop-Up Drainage Emitter, Fits 3" & 4" Sewer/Drain Pipes Compatible with Catch Basins, Channel Drains and Drainage Systems, Green

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.

Calvana Pop-Up Drain Emitter Cap Replacement (2-Pack) is designed to serve as the outlet point for underground drainage systems, allowing collected water to discharge efficiently when pressure builds.
