Claims

1. A system (1 ) enabling treating water from a water tank (3), which water tank (3) is arranged in a water distribution architecture also comprising one or more user units (8), said system (1 ) also enabling recycling of water or discarding of water not suitable to recycle, said system (1 ) comprising a water distribution unit (2), at least one water treating unit (6) and a sensor unit (7) arranged for measurement of at least water quality,

said water distribution unit (2) comprising one common user unit inlet (9) connectable via piping to said one or more user units (8) on their used water output side;

said water distribution unit (2) further comprising a contaminated water outlet

(10);

and said water distribution unit (2) further comprising at least one water recirculation port (1000) connectable via piping to the water tank (3) to enable flowing water between the water distribution unit (2) and the water tank (3); and wherein said at least one water treating unit (6) enables to treat water to increase the water quality thereof and where the sensor unit (7) is connected to a control unit, which, based on the measurement of the water quality, is arranged to decide if water should be recycled to the water tank (3) from the water distribution unit (2) or should be discarded via the contaminated water outlet (10) from the water distribution unit (2).

2. The system (1 ) according to claim 1 , wherein said at least one water recirculation port (1000) is two ports being a water recirculation outlet (12) connectable via piping to the water tank (3) and a water feed inlet (13) connectable via piping to the water tank (3) and/or to a fresh water inlet (14) of the water distribution architecture.

3. The system (1 ) according to claim 1 or 2, wherein the system (1 ) is a plug in solution for a water distribution architecture comprising one or more user units (8), a water tank (3) intended for water usage, a pump (4), a heating source (500) and a grey water tank (1 1 ) by means of

said water distribution unit (2) comprising one common user unit inlet (9) connectable via piping to said one or more user units (8) on their used water output side;

said water distribution unit (2) further comprising a contaminated water outlet

(10) connectable via piping to the grey water tank (1 1 );

said water distribution unit (2) comprising a water recirculation outlet (12) connectable via piping to the water tank (3);

and said water distribution unit (2) comprising a water feed inlet (13) connectable via piping to the water tank (3) and/or to a fresh water inlet (14) of the water distribution architecture;

and wherein said at least one water treating unit (6) enables to treat water to increase the water quality thereof and wherein the sensor unit (7) is connected to a control unit, which, based on the measurement of the water quality, decides if water may be recycled to the water tank (3) from the water distribution unit (2) or should be discarded and sent to the grey water tank

(1 1 ) from the water distribution unit (2).

4. The system (1 ) according to claim any of claims 1 -3, wherein the heating source (500) is a boiler connected to the water tank (3) and enabling to heat water being flown from the water tank (3) to the one or more user units (8).

5. The system (1 ) according to any of claims 1 -4, wherein the one or more user units (8) is one shower and at least one sink.

6. The system (1 ) according to any of claims 1 -5, wherein the one or more user units (8) is connected to the water tank (3) via piping both on a cold water side and on a hot water side.

7. The system (1 ) according to any of claims 1 -6, wherein the contaminated water outlet (10) connectable via piping to the grey water tank (1 1 ) of the water distribution architecture is operated by gravitational force.

8. The system (1 ) according to any of claims 1 -7, wherein said at least one water treating unit (6) is arranged inside of the water distribution unit (2).

9. The system (1 ) according to any of claims 1 -8, wherein said at least one water treating unit (6) is combined with a filter.

10. The system (1 ) according to any of claims 1 -9, wherein said at least one water treating unit (6) comprises a light unit.

1 1. The system (1 ) according to claim 10, wherein the light unit is a UV light.

12. The system (1 ) according to any of the preceding claims, wherein at least one sensor (100) of the sensor unit (7) is arranged inside of the water distribution unit (2).

13. The system (1 ) according to any of the preceding claims, wherein the water distribution unit (2) comprises a pump enabling to pump treated water from the water distribution unit (2) and out from the water recirculation outlet (12) and to the water tank (3).

14. A method comprising using a system (1 ) according to any of claims 1 -13, for flowing water from a water tank (3) of a water distribution architecture to the water distribution unit (2) of the system (1 ) to enable water treatment to increase the water quality.

15. The method according to claim 14, wherein the method also involves for a control unit to perform a decision if water should be recycled to the water tank (3) from the water distribution unit (2) or should be discarded and sent to the grey water tank (1 1 ) from the water distribution unit (2) in connection to usage of said one or more user units (8).

16. The method according to claim 14 or 15, wherein the water is flown from the water tank (3) to the water distribution unit (2) by means of gravitational force.

17. The method according to any of claims 14-16, wherein the water distribution unit (2) operates by a pre-defined water measurement, and optionally water treating, recirculation sequence for water flowing from and to the water tank (3) from the water distribution unit (2) when the one or more user units (8) are not in operation.

18. A water distribution unit (2) intended as a plug-in solution for a water distribution architecture comprising one or more user units (8), a water tank (3) intended for water usage, a pump (4), a heating source (500) and a grey water tank (1 1 ), and intended in a water recirculation system (1 ) incorporated in the water distribution architecture, wherein the water recirculation system (1 ) comprises at least one water treating unit (6) enabling treatment of water to increase the water quality thereof and a sensor unit (7) arranged for measurement of at least water quality,
