49615 PUREFLOW MANABLOC – 18‑PORT DISTRIBUTION MANIFOLD

The Viega 49615 PureFlow ManaBloc is a high‑performance residential and light‑commercial plumbing manifold engineered to deliver efficient, balanced, and centralized water distribution. This 18‑port system utilizes dedicated home‑run PEX lines, allowing every fixture in the building to receive consistent pressure, faster hot‑water delivery, and individual shut‑off control. Built from durable polysulfone, the manifold is fully compatible with potable water and designed to reduce leak points, installation complexity, and long‑term maintenance.

KEY FEATURES

• Home‑Run Distribution: Each fixture receives a dedicated PEX line for optimal flow and reduced pressure drop.
• Integrated Shut‑Off Control: ¼‑turn valves at every port allow isolation of individual fixtures without shutting down the entire system.
• Durable Polysulfone Body: Highly resistant to temperature, chemicals, and long‑term wear.
• Enhanced Efficiency: Faster hot‑water delivery and minimized water waste compared to branched plumbing.
• Flexible Compatibility: Works with PEX systems using appropriate press or crimp adapters.
• Reduced Leak Points: Centralized manifold design eliminates many behind‑the‑wall connections.
