Abstract

The invention provides water removal and storage system adapted for use in a building structure, said system comprising a water storage vessel for the removal and storage of water from one or more supply lines and resupply of water stored on demand. The system of the invention provides either a solution to the problems of flooding due to pipe rupture, interrupted water supply due to freezing, pipe rupture due to freezing, and water damage due to uncontrolled thaw. In one aspect the invention provides a controller adapted to receive control signals remotely, said signals control the valve to regulate the water supply pressure and/or flow rate to a desired set point.

Claims

1. A water removal and storage system adapted for use in a building structure, said system comprising:

a valve adapted to shut off a mains water supply line from at least one water pipe in the building structure;

a pump adapted to push or pull sufficient water from the water pipe into the water storage vessel; and

a flow transducer, a pressure transducer and a temperature transducer interfaced with a microcontroller, wherein at least one transducer provides measurement data to the microcontroller to control operation of the valve and the pump.

2. The water removal and storage system as claimed in claim 1 wherein said system is configured to operate at a range of ambient temperatures whereby freeze pipe rupture is prevented in said at least one water supply line or pipe.

3. The water removal and storage system as claimed in claim 1 wherein the storage vessel is pressurised and adapted to allow water to flow on said at least one supply line or pipe until the mains water is up to a desired pressure.

4. The water removal and storage system as claimed in claim 1 wherein the temperature transducer is adapted to operate the valve with means to switch the valve on and off depending on the temperature conditions.

5. The water removal and storage system as claimed in claim 1 wherein the flow transducer is adapted to control the opening and closing of the valve thereby filling or emptying of the storage vessel.

6. The water removal and storage system as claimed in claim 1 wherein the flow transducer supplies data to the microcontroller to provide automated operation of filling or emptying of the storage vessel dependent on the data supplied to the microcontroller.

7. The water removal and storage system as claimed in claim 1 wherein the pressure transducer is adapted to compensate for water losses in the building pipe-work by running the system to maintain a charge in the vessel.

8. The water removal and storage system as claimed in claim 1 wherein the storage vessel comprises a bladder that is inflated at a slightly lower pressure than the water pressure, such that when water is forced into the storage vessel the bladder is compressed.

9. The water removal and storage system as claimed in claim 8 wherein when water is required the vessel will discharge by action of the bladder expanding forcing water out of the vessel for use.

10. The water removal and storage system as claimed in claim 1 wherein the flow transducer, the pressure transducer and the temperature transducer temperature sensor, a flow sensor and a pressure sensor combined to provide data that determine a water leak in said at least one water pipe.

11. The water removal and storage system as claimed in claim 1 wherein the system is adapted to be retrofitted into existing plumbing systems of said building structure.

12. The water removal and storage system as claimed in claim 1 comprising an admittance valve to facilitate water removal from the at least one water supply line or pipe.

13. The water removal and storage system as claimed in claim 1 comprising an accumulator or storage vessel to partially store removed water and provide a controlled pressure overhead in the system.

14. The water removal and storage system as claimed in claim 1 wherein the storage vessel is positioned substantially in series with a mains water supply and adapted to be used in the treatment of potable water.

15. The water removal and storage system as claimed in claim 1 comprising one or more motorised valves placed in situ in said building and adapted to determine a leak in said at least one supply line or pipe at different locations in said building.

16. The water removal and storage system as claimed in claim 1 wherein the flow transducer is configured to monitor changes in flow rates in said at least one pipe and adapted to transmit said changes in flow rate to said microcontroller.

17. The water removal and storage system as claimed in claim 1 comprising multiple motorised valves located at all water reservoirs internal to the building structure.

18. The water removal and storage system as claimed in claim 1 comprising a non-return valve included to prevent flow reversal of water in at least one of said supply lines.
