I live in Phoenix and have worked on Mesa water. You have pretty high TDS (total dissolved solids) around 900 to 1200 PPM in your town. Remember the softener is ion exchange and is only going to remove the calcium and magnesium from this soup your city calls water. Sodium will replace the hardness in your tap water. As the water passes through your heater the hot water may change and these dissolved solids will form as solids on anything they may attach themselves to inside your hot water plumbing. As time goes on these particles will grow and break off then flow through your plumbing being caught by aerators and showerheads washing machine screens etc. Try a hot water filter and check it regulary this will filter out this stuff. Please have your water softener checked also operating in high TDS water the softener may need a good cleaning agent run through it.
