Viega 49625 30-Port ManaBloc – Centralized Control for Efficient Water Distribution

The Viega 49625 ManaBloc manifold offers a streamlined solution for distributing water to multiple fixtures in residential and light commercial installations. Featuring 30 dedicated outlet ports—18 cold and 12 hot—this unit provides point-to-point control for each line, allowing efficient isolation, maintenance, and flow management.

System Integration and Application

This 1/2" PEX crimp connection manifold is engineered for closed-loop plumbing systems using PEX tubing. It’s compatible with Viega PureFlow press and crimp fittings, making it a reliable component in new construction, remodeling, or system upgrades where direct runs to fixtures are desired.

Product Features

• 30-Port Configuration – Includes 18 cold and 12 hot outlets for distributing water throughout the structure.
• Integrated Shutoff Valves – Each port has its own valve, providing fixture-level control from a centralized location.
• Separate Supply Inlets – Distinct connections for hot and cold feeds support consistent temperature delivery and system balance.
• 100 PSI @ 180°F Rating – Handles elevated temperature and pressure requirements typical in residential and light commercial systems.
• PEX Crimp Compatible – Designed for 1/2" PEX tubing using standard crimp ring installation practices.

Installation Guidelines

Although the manifold is preassembled for convenience, it must be installed according to manufacturer specifications and local plumbing codes. The system should be mounted securely and kept accessible for maintenance. Each supply line should be labeled to correspond with the connected fixture for easy identification. A licensed plumber is recommended for proper pressure testing and balancing of the system.

Use Case for Contractors

This 30-port ManaBloc is well-suited for whole-home plumbing systems where quick access to fixture shutoffs is required. Its compact footprint and integrated isolation valves reduce installation time and future service disruption. The unit also minimizes fittings behind walls, contributing to fewer potential leak points and faster rough-in times.

Performance and Durability

• Built for Longevity – Made from corrosion-resistant PSU polymer, providing thermal stability and chemical resistance in potable water applications.
• Efficient Distribution – Delivers balanced flow rates to each outlet with minimal pressure drop.
• Modular Supply Connections – Inlet connections sold separately, allowing adaptation to project-specific requirements.
