- This drinking water is lost and its quantity is not negligible. There is therefore a need for a system provided for recovering this cooled drinking water for reuse in a useful manner, without it being lost.
- Patent FR 2947615 discloses a water recovery device in domestic installations. This device is intended to operate without the need of any other energy than the pressure already present in the sanitary circuit. It therefore uses a pressure regulator installed on the cold water line upstream of a pressure membrane storage container.

The operation of this device is therefore disturbed during pressure variations in the network. Being set for a given pressure, this device no longer works when one of the mains pressures changes or when the pressure drops over time within the storage container. Its operation is therefore random.
- this prior device can not operate if the network pressures are low, and only operates optimally when the water network is at a high pressure, which generates an increase in the flow rate for the water used and is antagonistic with its primary purpose of saving water.
- the prior device requires manual actuation opening and closing a bypass valve, which is tedious and is not suitable for everyday use where the user quickly ends up leaving the bypass valve close and stop using the device.

It requires a pressure differential artificially created by the addition of a low pressure circuit and therefore can not operate at the usual water pressures of domestic installations.
- This economizer device also uses a pressure switch and a flow sensor, expensive and likely to breakdown, which affects the overall reliability of the economizer device.
- this economizer device is not fully automated and it is the user who must select hot or cold water for each use.
- this economizer device only works with a mixer type faucet, and is not compatible with a mixing valve type.
- the object of the present invention is therefore to overcome the disadvantages of the prior art by proposing a new device for saving drinking water.
