Abstract

An water shutoff system is in-line with the main water supply for a property. It can detect an unexpected flow of water to automatically shut-off the water supply. The device has a home state and an away state, which can be controlled via a timer, ie to provide protection during the night. In the event of a power failure, the system will automatically shut-off the watery supply. A bypass valve can be operated to resume normal service. The system has a flow sensor and solenoid valve. A control panel has status LEDs and an arming/disarming key switch.

Description

Domestic / Commercial Water leak detection and automated shut off system
Description of system
The system is designed to be sited at the point of entry of the water supply. Its prime function is to detect the un-expected flow of water from this point onwards and to automatically shut off the water supply should such a situation arise.
The unit has been designed to allow the occupant to "set" the unit in an "AWAY" state; an example of this would cover the property when its occupants are away on holiday etc. Upon return the unit would then be returned to its normal "HOME" state, alternatively the unit can be controlled via a timer which would allow protection between assigned time intervals i.e. would provide protection during the night when no water is to be used.
The system comprises two main parts, a control panel with indications and the water interface unit. The only additional requirement is a240v supply to provide power.
In the event of a power failure the system will automatically "shut off' the water supply as a safeguard, if the supply of water has been interrupted by a power failure then the water supply unit is fitted with a "BY-PASS" valve that can easily be hand operated to resume normal service. As the system is designed to "fail safe" even when the unit is set to its "AWAY" state a power failure will not compromise its operation or level of protection.
This system does not require any type of remote or additional sensors, nor does it require any amount of leaked fluid to trigger its operation. The system is designed to be "in line" with the main supply and to operate immediately causing little or no damage to property or premises.
The control unit provides indications to notify the user of its status and any fault conditions that need to be addressed.
These comprise of the following: * HOME status led (Yellow)-system disarmed * AWAY status led (Blue)-system armed * LEAK DETECTED led (Red) * NORMAL led (green) * Key operated arming / disarming switch * Mains supply neon indication The unit is designed to be fitted either by a plumber or by the consumer, as 1 5mm "push fit" style connections are utilised, if any adaptation is required the fittings to accommodate this are already on the market and fitment is well within the scope of most people with little or no knowledge of plumbing.
To connect the control unit to the water interface unit both will comprises of plug in connections with suitably "ip" rated connectors for ease of installation.
The electrical operation requires a 240v earthed supply and RCD protection would be advisable, the inner workings could be either low voltage via an integral transformed supply or full mains voltage or a mixture of both, dependant on cost or individual component requirements. Note
This system could be utilised or designed to work with any fluid installation or factory based operations that require protection of this type.
Additionally, this unitlsystem could be fitted to cold water or hot water storage tanks, immersion heaters or any other vessel containing fluid in order to provide primary or additional protection against leaks and floods.

Claims (3)

  1. Claims I In the away mode the device will detect any unaccountable flow of water.
  2. 2 The device will immediately shut ofTthe mama water supply before any flooding occurs.
  3. 3 The device will automatically switch off water supply should the electricity service be interrupted or if a power supply fault occurs, for example a blown 4 During a power cut or fault the device can be manually overridden to resume normal water supply.The device also incorporates a timed mode so protection can be provided between pre set intervals (i.e, throughout the night).6 The control panel is set via a key switch for added security so as to eliminate Un-warranted usage (children for example). -a
