Water Manifold System And Method

Abstract

A system for distributing water within a building operates to distribute water from a pressurized water supply source to devices that receive water, such as faucets, toilets, showers, sprinklers, and hot water heating devices. The system includes at least one manifold which may be of unitary molded plastic construction and comprised of chlorinated polyvinyl chloride (CPVC). The manifold includes an entry port and a plurality of outlet ports which are also referred to as sockets. The sockets are configured to receive fitting inserts of various types that include water line connectors. The sockets are also configured to accept standard plastic water conduits therein in cemented relation. The water line connectors may include metallic connectors such as barbed fittings, which can be used to connect the manifold and crosslinked polyethylene (PEX) pipe in nonthreaded relation. Manifolds may be connected together to provide suitable distribution arrangements.

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims benefit pursuant to 35 U.S.C. §119(e) of Provisional Application 60 / 917,328 filed May 11, 2007, the disclosure of which is incorporated by reference as if fully rewritten herein.TECHNICAL FIELD[0002]This invention relates to water distribution systems and methods for distributing water to devices within a building. Exemplary embodiments relate to manifolds and systems which distribute potable water, hot water for heating, or water based fluids for other purposes, to multiple devices that receive water or fluids within a building. More particularly, exemplary embodiments relate to manifolds which are comprised of chlorinated polyvinyl chloride (CPVC) and which are suitable for connection though fitting inserts to multiple types of fluid conduits. Exemplary fluid conduits may of the type joined using solvent cement or other nonthreaded connections, and which are suitable for enclosure within the confines of a wall or ...

AI Technical Summary

Benefits of technology

[0006]Benefits may be achieved by providing manifolds and water distribution systems which are less complex, which can be configured to employ nonthreaded connections where required, are easily installed in a building, and are more readily expanded as the need may arise.

[0008]It is a further object of exemplary embodiments to provide versatile water manifolds for use in systems that are modular and suitable for in-place expansion and reconfiguration of water distribution capabilities.

[0018]In an exemplary embodiment, the manifold further includes an extension conduit portion. The extension conduit portion extends on an axial end of the manifold opposite the entry port. The extension conduit portion is in fluid communication with the interior area of the manifold. The extension conduit portion includes an extension opening thereon. The exemplary extension conduit portion is configured so that it can be operatively connected with an entry port of a similar further manifold. The further manifold may be configured with the sockets thereon in aligned relation with the sockets on the first manifold. Alternatively, the further manifold may be connected so it is angularly disposed relative to the first manifold, so that the sockets and the fluid connectors on the further manifold are angularly disposed from those on the first manifold. This can facilitate making more suitable conduit connections to the further manifold.

[0019]In the exemplary embodiment, the extension conduit portion on a manifold is configured so that when it is not to be connected to a further manifold or other conduit, the extension portion may be capped with a fluid cap. This may be done by cementing the cap in place to fluidly close the extension opening. At a later time when there is a need to expand or change the configuration of the system, the cap may be separated from the manifold. After this is done, there is sufficient remaining axial length of the extension conduit portion so that a further manifold may be engaged therewith. As a result, the water distribution system may be expanded or modified so as to accommodate additional connections to additional or different devices that receive water within the building.

[0027]In some exemplary embodiments, the manifold may be configured to facilitate the expansion or reconfiguration of the water distribution system. This may be done in situations where the manifold includes an extension conduit portion of sufficient length so that the connection to a cap or other structure which originally closes the extension opening may be changed. This may be done by cutting the cap or other structure from the extension conduit portion. The exemplary extension conduit portion is of sufficient length so that even after a cap or other structure has been separated, sufficient axial length of the extension conduit portion remains so that the remaining extension conduit portion can be joined in fluid tight relation to an entry port on a further manifold, conduit or other suitable structure. Joining the existing manifold to a further manifold may provide additional sockets to which fitting inserts and additional fluid conduits may be connected. This capability provides for the further expansion or modification of the water distribution system. Further, such expansion may be done using various types of fitting inserts and connectors suitable for connection to various types of devices and fluid conduits. As a result, fluid conduits may be extended to additional devices that receive water within the building.

Problems solved by technology

Often, copper or CPVC systems are installed in ways that are not readily expanded or reconfigured to accommodate additional water lines or changes to the water distribution system.

These types of manifolds are costly, and generally complex.

In addition, such manifolds are permanently assembled at the factory, and are not readily expanded or modified in the field.

A further drawback of such manifolds is that they are not compatible with solvent cements which are commonly used in construction for plastic pipe connections, particularly acrylonitrile-butadiene-styrene copolymer (ABS) piping or other materials that are used for wastewater connections.

In addition, the threaded connectors used by such manifolds are generally not suitable for enclosure within a wall or floor of a building structure.

This limits the areas and situations in which such manifolds can be used.
