Definitions

  • the present invention relates to a building having an electrically operated stop-cock capable of isolating an internal water distribution system from an external mains water supply and actuated by a manually operated switch, the use as a stop-cock of an electrically operated valve in combination with a manually operated switch, and a method of isolating the internal water distribution system of a building from an external mains water supply.
  • a stop-cock is usually located at the point at which the mains water supply enters the building.
  • a typical arrangement is shown schematically in figure 1.
  • the conduit 10 carrying the mains water supply is laid a minimum of two feet six inches (0.762 m) below ground level 12 in order that it might be protected from frost damage and crosses the property boundary 14 after first passing to a manual stop-cock 16 which is controlled by the water company. It is at this point, as far as the United Kingdom is concerned, that the responsibility for the water supply passes from the water company to the owner or occupier of the building.
  • the water supply then passes either under or through a wall of the building 18 and rises to just above floor level 2C at which point there is provided a private stop-cock 22 operable by the owner or occupier of the building to control the quantity of water supplied thereto.
  • stop-cock since the stop-cock is typically as old as the building itself, they have often seized or are so stiff as to make turning them impossible without the aid of the appropriate tools. Even with the right tools there is the danger that the application of an excessive torque might cause part of the stop-cock to shear off.
  • a building having an internal water distribution system in communication with an external mains water supply; and an electrically operated stop-cock connected to the mains water supply, and capable of isolating the internal water distribution system from the external mains water supply, characterised in that the building further comprises a manually operated switch connected to the stop-cock such that when the switch is in a first position water is able to flow continuously through the stop-cock from the external mains water supply to the internal water distribution system and when the switch is placed in a second position the stop-cock is actuated to immediately prevent further flow therethrough.
  • the switch may be located remotely from the stop-cock.
  • the building may be provided with an intruder alarm system to which the stop-cock is connected, the stop-cock being actuated on actuation of the alarm system.
  • the stop-cock may comprise a solenoid valve.
  • a stop-cock of an electrically operated valve means in combination with, and actuated by, a manually operated switch such that when the switch is in a first position water is able to flow continuously through the valve means from a mains water supply to a private water distribution system and when the switch is placed in a second position the valve means is actuated to immediately isolate the private water distribution system from the mains water supply.
  • a method of isolating the internal water distribution system of a building from an external mains water supply with which the internal water distribution system is in communication comprising the step of providing an electrically operated stop-cock at the junction between the internal water distribution system and the external mains water supply, characterised in that the method further comprises the steps of providing a manually operated switch connected to the stop-cock such that when the switch is in a first position water is able to flow continuously through the stop-cock from the external mains water supply to the internal water distribution system and when the switch is placed in a second position the stop-cock is actuated to immediately isolate the internal water distribution system; and operating the switch so as to move the switch from the first position to the second position.
  • the switch may be located remotely from the stop-cock.
  • the building may be provided with an intruder alarm system to which the stop-cock is connected and the stop-cock actuated on actuation of the alarm system.
  • the stop-cock may be connected to an intruder alarm system and actuated on actuation of the alarm system. In this way when the owner or occupier leaves the building and as a matter of routine actuates the alarm system he simultaneously actuates the stop-cock and isolates the internal water distribution system from the mains water supply.
  • a range of electrically operated valves are manufactured by many companies such as, for example, in United Kingdom by Danfoss Limited of Perivale Industrial Park, Greenford, Middlesex UB6 7QE.
  • valve as the electrically operated stop-cock is that in the event of an electrical power failure, the valve will automatically close isolating the building's internal water distribution system from the external mains supply. If required, the valve can be reopened manually by the use of a suitable magnet before the electricity supply is restored.
  • a solenoid valve Another advantage of a solenoid valve is that its electrical components are completely enclosed in a water-tight casing so that in the event of a leak elsewhere in the internal water distribution system the solenoid valve may still be actuated to isolate the system without endangering the user.
  • the electrically operated stop-cock may be placed in series adjacent the existing stop-cock.
  • the existing stop-cock may then simply be left in the open position and the electrically operated stop-cock actuated in the manner previously described in order to control the supply of mains water to the building.

Claims (9)

  1. Gebäude mit einem inneren Wasserverteilersystem in Verbindung mit einer externen Hauptwasserversorgung; und einem elektrisch betätigten Absperrhahn, der mit der Hauptwasserversorgung verbunden ist und in der Lage ist, das innere Wasserverteilersystem von der externen Wasserversorgung zu isolieren, dadurch gekennzeichnet, dass das Gebäude ferner einen manuell betätigten Schalter aufweist, der mit dem Absperrhahn verbunden ist, sodass dann, wenn sich der Schalter in einer ersten Position befindet, Wasser kontinuierlich durch den Absperrhahn von der externen Hauptwasserversorgung zu dem inneren Wasserverteilersystem fließen kann, und wenn der Schalter in einer zweiten Position angeordnet wird, der Absperrhahn aktiviert wird, um einen weiteren Durchfluss durch ihn hindurch sofort zu verhindern.
  2. Gebäude nach Anspruch 1, wobei der Schalter von dem Absperrhahn entfernt angeordnet ist.
  3. Gebäude nach Anspruch 1 oder Anspruch 2, wobei das Gebäude mit einem Einbruchsalarmsystem versehen ist, mit dem der Absperrhahn verbunden ist, wobei der Absperrhahn bei Aktivierung des Alarmsystems aktiviert wird.
  4. Gebäude nach einem der Ansprüche 1 bis 3, wobei der Absperrhahn ein Solenoidventil aufweist.
