Low pH or “acid water’ can mean big problems for your plumbing, pipes and fixtures. The corrosive action of this type of water in your pipes is evident by the telltale bluish-green stains on your sinks or tubs (rust colored stains if you have galvanized iron pipes). These stains are evidence that your water is slowly dissolving your pipes and fixtures.
If this condition is allowed to continue over time, leaks in your plumbing system could develop. If the condition persists over extended periods of time, the pipes will become so thin that they may all have to be replaced.
