Warning signs worth a closer look
Stains on sinks and tubs, cloudy drinking water and spots on dishes may seem cosmetic, but they can signal minerals or other substances in the supply. Strange tastes or odors deserve attention too, since they shape which treatment makes sense.
Scale on faucets and appliances is more than unsightly. It can make a dishwasher, washing machine or water heater work harder over time. Note where the buildup appears and how quickly it returns after cleaning.
