1. A system enabling treating water, said system being a part of a water distribution architecture comprising a water tank and one or more user units, wherein the water tank enables treating water, said system also enabling recycling of water or discarding of water not suitable to recycle, said system comprising:
a water distribution unit;
at least one water treating unit; and
a sensor unit configured to measure at least water quality,
wherein said water distribution unit comprises:
one common user unit inlet connectable via piping to said one or more user units on their used water output side;
a contaminated water outlet;
and at least one water recirculation port connectable via piping to the water tank to enable flowing water between the water distribution unit and the water tank, said at least one water recirculation port is two ports being a water recirculation outlet connectable via piping to the water tank and a water feed inlet connectable via piping to the water tank and/or to a fresh water inlet of the water distribution architecture,
wherein said at least one water treating unit is configured to treat water to increase the water quality thereof,
wherein the sensor unit is connected to a control unit, which, based on the measurement of the water quality, is configured to decide if water should be recycled to the water tank from the water distribution unit or should be discarded via the contaminated water outlet from the water distribution unit,
wherein the system is a plug-in solution for the water distribution architecture, which further includes a pump, a heating source and a grey water tank, wherein:
said contaminated water outlet is connectable via piping to the grey water tank;
and said water distribution unit comprising a water feed inlet connectable via piping to the water tank and/or to a fresh water inlet of the water distribution architecture;
and wherein the control unit, based on the measurement of the water quality, decides if water should be recycled to the water tank from the water distribution unit or should be discarded and sent to the grey water tank from the water distribution unit,
wherein the system is connectable to the water distribution architecture, and wherein the heating source is a boiler connected to the water tank and enabling to heat water flowing from the water tank to the one or more user units, and
wherein the contaminated water outlet connectable via piping to the grey water tank of the water distribution architecture is operated by gravitational force,
wherein the one or more user units includes one shower and at least one sink,
wherein said at least one water treating unit is arranged inside of the water distribution unit,
wherein at least one sensor of the sensor unit is arranged inside of the water distribution unit, and
wherein the water distribution unit comprises a pump configured to pump treated water from the water distribution unit and out from the water recirculation port to the water tank.
