Viega 49615 ManaBloc Manifold – Streamlined Plumbing Distribution with Precision Control

The Viega ManaBloc 49615 manifold is engineered for high-efficiency plumbing systems, providing direct distribution from a central location to individual fixtures. Designed with 18 integrated ports—10 cold and 8 hot—it offers precise control and improved flow efficiency for residential or light commercial systems. Built from rugged Polysulfone (PSU), this manifold supports long-term durability and resistance to scale, corrosion, and harsh water conditions.

Professional-Grade Water Control

Each port is equipped with an individual shut-off, allowing for easy isolation during maintenance or repairs without affecting the entire system. The full-flow design ensures minimal pressure drop even during simultaneous usage, reducing callbacks and improving system performance.
