Scope
This specification designates requirements for the PureFlow MANABLOC Manifold Plumbing Control Unit. The MANABLOC parallel
water distribution system supplies water to individual plumbing fixtures through dedicated ports and distribution lines. Each port
(outlet) is equipped with a built-in shut-off valve to provide control for each fixture from a central location. The MANABLOC has
separate hot and cold water inlets and ports to manage the entire plumbing system. A variety of fitting options are available for the
MANABLOC distribution ports, including PEX Compression, Bronze PEX Press, Brass PEX Crimp and PolyAlloy PEX Crimp fittings.
These distribution connections come complete with the MANABLOC when ordered. However, supply connections and fixture
transition fittings are not included with the unit but are available separately.
Materials
The modular MANABLOC sections are molded from polysulfone (PLS) plastic. This material is used extensively in the medical
industry and is highly resistant to hot water, chlorine and other chemicals typically found in potable water systems. The other
components making up the MANABLOC consist of corrosion-resistant metals and engineered plastics that have been chosen
specifically for each purpose. The stiffener used in the compression port fitting assembly is manufactured from 304 stainless steel.
Marking and Certification
MANABLOC units are marked with the product name, unit part number, material designation, production date and marks of third-
party certifications by NSF International (NSF-pw) to ASTM F877 and ANSI/NSF standards 14 and 61, CSA B137.5 Warnock Hersey,
and are listed with IAPMO as meeting the requirements of the Uniform Plumbing Code.
Recommended Uses
The MANABLOC is recommended for use in hot and cold potable water distribution systems in single and multifamily dwellings,
as well as multiple-unit structures (apartments, condos, hotels, motels, etc.). Maximum pressure/temperature rating is 100 psi @
180°F. The MANABLOC is not to be used directly in line with hot water domestic recirculation loops. PureFlow MANABLOC system
components are not interchangeable with components and tubing from other suppliers. For information on other hot and cold
applications not listed here, consult with your Viega representative.
Handling and Installation
The MANABLOC must be protected from UV exposure and petroleum products that can damage them. Use of these materials
in hot and cold water distribution systems must be in accordance with good plumbing practices, applicable code requirements,
and current installation practices available from Viega. Contact a Viega representative or the applicable code enforcement
bureau for information about approvals for specific applications.
