Claim 13:
14. A reverse osmosis water system for use with a water source, the system comprising:
an inlet and an outlet, the inlet receiving untreated water from the water source;
a reverse osmosis cartridge fluidly coupled to a medial waterline, the medial waterline providing a first portion of pretreated water to the reverse osmosis cartridge; and
an unfiltered waterline fluidly coupled to the medial waterline and receiving a second portion of pretreated water at a first flowrate, the unfiltered waterline having a flow restrictor and a blend valve, the flow restrictor reducing the first flowrate to a second flowrate; and
a blend waterline fluidly coupled to the medial waterline downstream of the reverse osmosis cartridge and fluidly coupled to the unfiltered waterline downstream of the flow restrictor and the blend valve, the unfiltered waterline providing unfiltered water to the blend waterline at the second flowrate, the reverse osmosis cartridge providing filtered water to the blend waterline at a third flowrate, the flow restrictor and the blend valve controlling the second flowrate to be substantially equal to the third flowrate.
