WATER MANAGEMENT SYSTEM

A preferred embodiment of the present invention is directed to a water management system. One aspect of a version of the invention comprises a manifold with separate lines running to separate appliances and fixtures. Each individual line detects leaks, alerts that a leak has occurred, shuts down only the leaking line, and provides a visual cue to alert that the line is leaking. In one embodiment of a version of the invention, the water management system comprises a hot water heater water management system that detects leaks, sounds an alarm, shuts down the water heater power, and drains the water heater. In a preferred embodiment, once the water heater is repaired and refilled, the power is automatically restored.

Description
FIELD OF THE INVENTION

A preferred embodiment of the invention refers to a building water management system for detecting leaks and water loss and shutting down the compromised lines.

BACKGROUND

Traditional piping systems based on copper or hard metal pipes and rigid connectors are giving way to new methods. One new method for water distribution gaining acceptance in the home and commercial building industry is the use of manifold plumbing systems. Unlike the conventional copper-pipe trunk and branch infrastructure, manifold plumbing systems function like circuit breakers for water.

Manifold plumbing systems are control centers for hot and cold water that feed flexible cross-linked polyethylene (PEX) supply lines to individual fixtures. Manifolds, together with PEX lines, offer installation-related cost advantages over conventional rigid pipe plumbing systems. The unique features of PEX piping make it ideal for use in manifold-type system designs, commonly referred to as home-run plumbing systems. In this design, all fixtures are fed from dedicated piping that runs directly and unbroken from a central manifold or manifolds.

Whether a manifold or conventional plumbing system, the first step in stopping a leaking fixture or pipe is to be aware that a leak exists. Generally, a water leak is silent, or very quiet. Attempts to address these problems can be found in U.S. Pat. No. 5,428,347 and U.S. Publication Ser. Nos. 10/031,5245 and 06/020,8912. However each one of these references suffers from many disadvantages. Primarily, an audio or visual alarm cannot automatically shut down the leaking water supply system. An alarm is simply made to notify the user responsible for correcting the leak. Because an alarm is useless if no one is there to hear it, leak detection systems based on audio or visual alarms must be equipped with other shut-off elements. Furthermore, the types of alarms available measure leakage from only one pipe or fixture. Thus a complicated system of alarms must be equipped to fully analyze leakage from the various fixtures and appliances present in a home, apartment complex, or commercial building.

Because alarms alone cannot automatically shut off water supplies, attempts have been made to solve this problem as found in U.S. Pat. No. 6,675,826 and U.S. patent Publication Ser. No. 13/009,2242. However, each of these references suffers disadvantages. First, the disclosures are used to measure one, or only a few, water lines. Additionally, the disclosures require adding additional pieces to the water line and/or fixture. Furthermore, if a leak is detected, the entire water supply is shut-off, thus shutting off water to other fixtures and appliances.

Of all the fixtures and appliances, one of the most dangerous and destructive is a leaking or burst hot water heater or hot water heater pipe. Not only does a hot water heater generally hold a large capacity of water, but the water container therein is extremely hot. A sudden discharge of the hot water stored inside of the water heater could cause extreme burning to a human or domestic animal. In addition, the massive amount of rushing hot water could quickly flood basements or other areas of the home.

Information relevant to attempts to address these problems can be found in U.S. Pat. Nos. 5,345,224; 5,229,750; 4,572,113 and U.S. Publication Ser. Nos. 12/027,5927; 04/0206405. However, each one of these references suffers from one or more of many disadvantages.

First, the holding reservoir used in many of the disclosures may also have an undetected leak. Additionally, the reservoir may overflow if a pipe bursts, thus creating a more dangerous situation, as an increased rush of hot water will be released when the reservoir overflows. Another disadvantage is that some systems were created for draining water from the system before leaving the home or building for an extended period of time during the winter, not quickly detecting and draining leaks. Other systems do not automatically shut off a leaking or burst hot water heater. Another disadvantage is that many systems do not drain the water left in the water heater. Another disadvantages is that many systems do not automatically turn off the hot water heater when a leak has been detected, or when the water heater has been drained. Another disadvantage is that many systems do not automatically turn the power back on when the tank has been refilled.

As noted from the foregoing, problems exist in the field relating to leak detection, leak control, and water management systems. Thus, a need exists in the art for a water management system that overcomes the disadvantages of the current systems and methods.

In a preferred embodiment of a version of the invention, all fixtures and appliances will be constantly monitored. In addition, the hot water heater will be monitored. Therefore, the water management system will significantly reduce the risk of leaks and flooding.

A primary advantage of a preferred embodiment of the water management system is the simplicity of the system and ease at which the system can be installed and serviced. Additionally, aspects of features of the invention have the advantage of allowing one to quickly find the leak without cutting holes in the wall or sheetrock. Additionally, aspects of the invention allow a homeowner, plumber, or technician to instantly know which port off of the manifold is leaking. Because each water line and fixture is supplied separately, any water loss from a leak will be minimal because the only water that will be able to escape from the leaking pipe will be the amount in the pipe before the valve is shut off at the port. Therefore, one advantage of an embodiment of the invention is that the water management system will not only shut down the leak, but will also identify which water line has a leak. Additionally, one embodiment of the water management system further detects leaks coming from the water heater.
