== PEX Manifold ==The manifold is the primary hub for hot and cold water in a home with all PEX plumbing. A manifold Pex plumbing system allows for easy maintenance and better water distribution over traditional systems. Think of the central manifold the same way as your electrical breaker box, except for water. You have a central command with NO connectors between the manifold and appliances, the largest source of weakness in traditional systems. Proven technology over decades, it is finally changing the way we plumb.[[Image:PEXManifoldManabloc.jpg|thumb|left|The popular Vanguard Manifold Manabloc]]A popular PEX Manifold is the Vanguard Manifold Manabloc for home plumbing systems. The MANABLOC control unit has individual shut-off valves to allow the homeowner to turn off a single fixture without effecting the rest of the home. The valves are labeled to indicate which fixture it controls in the home.The system distributes water efficiently and economically. By sizing the lines according to the demand of each fixture, homeowners enjoy much faster hot water delivery which results in significant water and energy savings. The 1 1/4" reservoir in the MANABLOC maintains more consistent supply of water pressure reducing the potential for drastic temperature changes at fixtures; even when other fixtures are operated simultaneously. The performance of a conventional plumbing system during multiple fixture operation can't compare to a MANABLOC system.
