Water conditioning systems having diversion devices

A portable water conditioning system, comprising:

• an incoming water inlet;
• a reverse osmosis stage in fluid communication with the incoming water inlet, the reverse osmosis stage having a permeate outlet and a concentrate outlet;
• a first sensor configured to detect a first condition of the water before the reverse osmosis stage;
• a second sensor configured to detect a second condition of the water after the permeate outlet, wherein the first and second conditions each comprise a level of total dissolved solids of the water;
• a deionizing stage in fluid communication with a pure water outlet;
• a diversion device having diversion valve and a flow control valve, the diversion valve being configured to selectively place the concentrate outlet in fluid communication with a waste water outlet, the flow control valve being configured to ensure a determined flow around the diversion valve to the waste water outlet;
• a bypass valve configured to selectively place the permeate outlet in fluid communication with one or more of the waste water outlet, the deionizing stage, and the pure water outlet;
• and
• a controller in communication with the first and second sensors and the diversion device, the controller being configured to determine a percent rejection of the reverse osmosis stage after the controller controls the bypass valve to place the permeate outlet in fluid communication with the waste water outlet.
