The 20″ SuperFlow 360 Pebble Top Drain Dark Gray is a pebble top drain with an integrated sump, engineered for powerful water flow and a seamless finish. With a design that allows pool plaster, tile, or aggregate to be applied directly to the lid, it blends discreetly into the pool floor while delivering exceptional performance. Offering up to 360 GPM in SuperFlow mode and compliant with industry standards, this unblockable drain requires no secondary suction point—making it ideal for residential and commercial installations. Compatible with multiple pipe sizes and flush-mounted to avoid snagging, it’s a high-efficiency, low-visibility solution for modern pool builds.
