Perhaps you’ve heard the term “hard water” before. It may sound a little alarming in regards to your water quality, but it’s actually okay–for you that is. It’s another story when it comes to your plumbing system. Hard water is water with a high level of minerals in it. Namely, we mean calcium and magnesium, sometimes even a bit of iron. But like we said, while these are harmless to you, we can’t say the same for your pipes and plumbing appliances.
Scaling–or the deposits that get left behind from hard water–will impact your water heater worse than any other part of your plumbing system. While it’s relatively easy to clean scale out of a faucet, the same can’t be said when it comes to your tank water heater.
