Not all water problems show up as dramatic warning signs. In fact, many of the most common water issues Canadian homeowners experience are easy to dismiss as “normal” — a bit of staining, some scale buildup, or a slight change in taste. Over time, though, these small issues can quietly cause damage to plumbing, appliances, and water-using fixtures.

Understanding what these early signs mean can help you address water quality issues before they turn into expensive repairs or long-term inconvenience.

A water test is more than a simple pass or fail result. It provides insight into what’s actually in your water, how different parameters interact, and whether those levels are likely to affect your home or long-term water quality. Factors like pH, hardness, iron, bacteria, and emerging contaminants such as PFAS each tell a different part of the story. Understanding what these numbers mean — not just whether they meet a guideline — is key to deciding when treatment is necessary and when it’s simply optional.

PFAS, often referred to as “forever chemicals,” are becoming an increasing concern for households across North America. These man-made chemicals are commonly found in everyday products like non-stick cookware, stain-resistant fabrics, and firefighting foam. Because PFAS don’t break down easily, they can persist in the environment and accumulate in the human body over time. Even at low levels, long-term exposure through drinking water may pose potential health risks, which is why understanding where PFAS come from and how to reduce exposure at home is an important step in protecting your household’s water quality and overall well-being.
