Viega 49620 ManaBloc 24-Port Manifold – Centralized Plumbing Control with Maximum Efficiency

The Viega ManaBloc 49620 manifold system is engineered for high-performance water distribution, combining centralized control with consistent pressure and flow across all connected fixtures. This 24-port unit, configured with 15 cold and 9 hot outlets, simplifies plumbing layouts, reduces connection points, and enhances both installation efficiency and long-term system performance.

Designed for Demanding Residential and Light Commercial Use

Constructed from chemically resistant polymer and rated for up to 100 PSI at 180°F, the ManaBloc 49620 provides reliable service even in elevated temperature and pressure environments. Integrated shut-off valves at each port allow fast service access without disrupting the rest of the system—ideal for maintenance-intensive properties or custom installations.
