Questions & Answers

Q: I have acidic water, about 5.6 Ph. How long or how many gallons will this filter last or correct to near 7.0 Ph? My home piping is copper. Is this a good solution to the problem? Terry
Asked by:  - 5/29/2014 (Submit an answer)
A: This is approximately 25,000 gallons but it can vary depending on the flow rate. It's probably best to check every 10,000 gallons. It will correct close to pH 7 and may over correct slightly depending on flow rates. Yes, this is great for copper pipes.
