18 Port - 1/2" VIEGA MANABLOC, 8 hot ports 10 cold ports

The Viega 18 Port MANABLOC is a unique plumbing water distribution system that can provide homeowners with dramatic water and energy savings. Each fixture in a house (e.g. shower, kitchen sink, toilet) is fed by its own flexible water distribution line, made of PEX tubing, that runs directly from a central manifold system, called the Viega MANABLOC. By providing each fixture with its own distribution line (blue indicates cold water and red indicates hot water), the line can be made just the right size based on the amount of water that is needed. For example, shower heads may need more water than low-flow fixtures such as toilets or dish washers, so larger lines can be run from the MANABLOC to the shower. This results in faster hot water and reduced waste. Combined with Viega PEX tubing, the MANABLOC offers additional benefits to both the plumber who is installing the system and the homeowner who uses it.

Additional benefits include:

  • Fewer fittings (connections) behind the walls
  • Individual shut-off valves
  • Balanced water pressure
  • Works with all pex tubing manufacturers

***Includes all crimp insert fittings for distribution lines. All supply fittings sold separately.***
