1. A water treatment system for treating water in a building, the water treatment system comprising:
an input pipe;
a first pipe;
a second pipe;
a third pipe;
a water softener device configured to admit an input water stream from the input pipe and to provide first and second outlet streams to the first and second pipes, respectively, the first outlet stream having a first water hardness value of water hardness, and the second outlet stream having a second water hardness value of water hardness;
a regulating device configured to receive the first and second outlet streams from the first and second pipes, respectively, and to provide a third outlet stream through the third pipe; and
a water treatment computer including non-transitory computer-readable medium comprising instructions for treating water that, when executed by a processor, cause the processor to perform the following operations:
receiving an input of a water hardness value of water hardness from a user interface of an appliance or outlet; and
transmitting first control instructions to the regulating device to adjust a ratio of a first flow rate of the first outlet stream relative to a second flow rate of the second outlet stream to provide the water hardness value in the third outlet stream to the appliance or outlet through the third pipe,
the regulating device configured to adjust the ratio of the first flow rate of the first outlet stream relative to the second flow rate of the second outlet stream to provide the water hardness value in the third outlet stream to the appliance or outlet through the third pipe.
