Product Overview

The Paramount MDX-R3 Drain Sump 004262203400 is a genuine replacement and new-construction component designed for compatible non-adjustable concrete pool installations using the Paramount MDX-R3 debris-drain system. The sump forms the permanent lower drain body installed within the pool structure and provides the foundation for the final MDX-R3 drain components.

This version includes a clear construction cap that protects the open sump during gunite, concrete, plaster, and interior-finish work. The cap helps prevent rocks, cement, plaster, dirt, and construction debris from entering the drain body or connected plumbing before the final cover and internal components are installed.

The MDX-R3 system is designed to remove large debris and dirt delivered to the drain, making it particularly useful when paired with a compatible Paramount in-floor cleaning and circulation system. Paramount identifies the MDX-R3 as a VGB-compliant debris-drain system when all required components are properly installed according to the manufacturer’s instructions.

This listing includes the non-adjustable concrete sump and clear construction cap only. The finished drain cover, funnel assembly, SDX2 safety drain, hardware, plumbing fittings, and complete MDX-R3 system are not included unless specifically stated.

Benefits

Installing the correct sump during pool construction is essential because the component becomes permanently embedded within the concrete pool structure. The non-adjustable design is intended for installations where the final drain elevation and pool-floor thickness are accurately established during construction.

The clear construction cap makes it easier to see the protected opening while helping contractors keep the sump clean throughout the building and finishing process. Preventing debris from entering the plumbing can reduce cleanup time, prevent clogged drain lines, and simplify installation of the remaining MDX-R3 components after the pool interior is completed.

Specifications

Installation Information

The sump must be positioned and secured before the pool shell is completed. Confirm the finished pool-floor elevation, plumbing location, drain orientation, and required concrete coverage before installation.

Connect the sump to the approved suction plumbing according to the current Paramount MDX-R3 installation manual. Keep the clear construction cap installed during gunite, plaster, and finishing work to prevent debris from entering the sump.

The MDX-R3 and all related suction-outlet components must be installed in accordance with Paramount instructions and applicable federal, state, local, and pool-industry safety codes. Installation should be completed only by a qualified pool builder familiar with VGB-compliant suction systems.
