A household of three adults in SE PA. Well water with pH of 5.8 and hardness of 14.97 gpg, iron 0.05 mg/l. We have a 62 gallon pressure tank, Whirlpool water softener and set of sediment filters: 50 and 20 micron. The current problem is water acidity causing copper plumbing corrosion. I’ve contacted several companies are I’m on the fence what type of system to get to increase the pH. One company is adamant about getting a soda ash injection type of system over a Calcite Acid Neutralizer due to high hardness level. Another one claims that I’d be perfectly OK with and wants to sell me Clack 2.5 upflow gravel bed with calcite, no electronic valve. I’m leaning toward a calcite type of neutralizer but not sure what type to get. One of the concerns is not to cause significant water pressure drops. Any guidance is appreciated.
