The Soda Ash Solution to Extremely Low pH

Hello Kevin,

Thank you for contacting us through our website.  You wrote:


“What are my options/costs for raising pH?  Shallow well Jet pump JP-100-c Little Giant Pump with 1" connections to Well-x-trol wx-203.  Using nitrate and 7stage carbon filters for drinking water. 1344 Sq foot house, 2 full baths and four people living here. Septic system present.”


Since your pH is so low at 4.75, we would suggest that you use a soda ash system to fix the problem.  Soda ash is made of sodium carbonate, which reacts with the dissolved acidity in your water to bring up the pH and neutralize its corrosive qualities.  This is a good alternative to a calcite (crushed limestone) neutralizer which raises hardness considerably, and soda ash works very well for even extremely low pH levels.  





I recommend the 220 volt pump so that it matches the pressure switch voltage.  This way, it can be wired to the pressure switch to turn on when the well turns on, so it would be injected when your water is running.  We also would suggest a 35-gallon solution tank, and also an inline mixer to ensure that the soda ash mixes consistently and efficiently with your water.
