摘要： A reverse osmosis water system including a housing, a reverse osmosis cartridge, an unfiltered waterline, and a blend waterline. The housing includes an inlet and an outlet. A medial waterline transports pretreated water to the reverse osmosis cartridge. An unfiltered waterline includes a flow restrictor. A blend waterline transports a blended water mixture to the outlet. The blended waterline receives filtered water at a first flowrate from the medial waterline and unfiltered water at a second flowrate downstream of the flow restrictor. The flow restrictor provides the second flowrate at a substantially equal rate to the first flowrate.
