1. A liquid dosing system comprising:
a cartridge comprising:
a reservoir configured to store an additive;
an additive output vessel in fluid communication with the reservoir; and
a cartridge outlet in fluid communication with the additive output vessel; and
a housing comprising:
a water passage in fluid communication with an inlet of the housing and an outlet of the housing;
a receiving portion configured to at least partially receive the cartridge when the cartridge is connected to the housing, the receiving portion comprising:
a receiving port in fluid communication with the water passage, the receiving port configured to receive at least some of the additive from the cartridge outlet when the cartridge is connected to the housing; and
a motor configured to engage in mechanical communication with the additive output vessel when the cartridge is connected to the housing;
a flow meter configured to measure a flow rate and output flow rate data indicative of the flow rate; and
a controller in electrical communication with the flow meter and the motor, the controller configured to:
receive the flow rate data from the flow meter; and
output, based at least in part on the flow rate data, instructions for the motor to output a predetermined amount of the additive for mixing with water flowing through the water passage,
wherein the controller is configured to output the instructions for the motor in response to determining, based on the flow rate data, that the water has stopped flowing through the water passage.
