Last year we had our outside well piping system replaced and this year it's time to tackle the low pH water. When tested last year at a lab it came out 5.0 pH, 1 gtg hardness, 36 ppm TDS, 0.00 ppm iron (<.3). Today a local water treatment company tested it with their traveling kit and came up with similar #'s (5-5.5 ph, lower hardness, and no iron). The low pH water also takes a toll on trying to grow grass as well (ie low pH soil). I've already replaced some 3/8" copper piping in the basement so it's clear the low pH is taking its toll. The only question is what system will do the job efficiently and with minimal cost. In reading some older threads they seemed to suggest a calcite system which can both handle the low pH and be far less maintenance and tweaking. Having to replace a $500 metering pump someday in an injection system sounds like a weak link. The costs given to me for each system were $1700 calcium carbonate or $1500 soda ash. In either case I'd prefer to stay away from sodium systems that could affect my blood pressure control.

Household usage is probably 100 gpd or less. The pump is rated at 10 gpm but puts out up to 18 gpm per mfg pump curve. The actual flow from the 40-60 psi water tank is probably 1-2 gpm. Our house is part of a 100 home community around a lake and nearly all the homes have low pH water (6-6.5). Ours happens to be lower than most. The well is an 18 ft deep by 3 foot wide surface well about 200 yds from the lake. Fwiw the entire town of 10,000 people all have private wells.

Any thoughts or inputs would be most appreciated. I want to try and only do this once so I'm back to this fine forum for help. Last year I received some good inputs on how to tackle my well pump replacement. Thanks.
