Helhom 4 in. Pop Up Drainage Emitter for Sewer and Drain Fittings, Replacement Pop-Up Drainage Emitter Lid

This drain pipe pop-up emitter functions as a reliable discharge point for a wide range of residential and commercial drainage systems. Its pop-up cover automatically rises up to 1 in. when water pressure increases, then closes as flow slows down, with a flat design that ensures safe, straightforward daily use. It fits standard 4 in. hub sewer and drain fittings, and can connect to other pipe types using appropriate adapters. When not in active use, the closed cover blocks debris and rodents from entering the drainage pipes, protecting the internal network from clogs and costly damage. As part of a complete drainage setup, it redirects collected stormwater runoff and standing water away from structures, erosion-prone land, and poorly drained areas, helping prevent expensive property damage before excess water builds up.
