Hayward SUMP ADJ CONC W/CAP MDXR3

The Hayward Sump Adjustable Concrete with Cap for the MDXR3 is a specially designed main‑drain sump used in concrete pool construction to ensure proper placement, alignment, and hydraulic performance of the MDXR3 drain assembly. Its adjustable design allows installers to fine‑tune the height and positioning of the drain body before the concrete is poured, helping achieve a precise, flush fit with the finished pool surface. The included cap protects the sump during construction and maintains the correct opening for the drain installation. Built for durability and compatibility with high‑flow safety drain systems, it supports reliable suction performance while helping maintain compliance with modern safety standards.
