How clean the water in your plumbing system is depends on where you live, and the efficiency of your city’s water treatment plant. No matter how good your city’s municipal treatment systems are, though, they cannot be 100% effective. There will always be some level of contaminants that manage to escape the treatment process and make it into your home. Not to mention that if you get your water from somewhere other than the city in which you live, it may not be getting any treatment at all. It’s important that you take steps to protect your home from the dangerous contaminants that might infiltrate it through the water supply. The best way to do that is to install a water treatment system. Read on for some of the warning signs that you need to install a water treatment system in your home.
