Soda Ash Injection:

An alkaline solution of soda ash in injected into the water line, usually ahead of the water storage tank, to neutralize the acidity. Typically they're wired into the water pressure switch to operate simultaneously with the well pump. Alternatively, a flow-switch in conjunction with a "blending" tank can be used.

• Can also use potassium carbonate to avoid adding sodium to the water
• Polyphosphate can be fed simultaneously (creates a protective coating inside the pipes)
• Does not raise "hardness"
• Earliest possible treatment point
• Can raise the pH above 7.0 if necessary
• Average household injects approximately a quart of solution per day
• Average installed cost: $900-1,200
