Common water problems in Dekalb
Hard water problems
Hard water results from high levels of calcium and magnesium in water. Hard water minerals stick to everything water touches, and do more than leave an unsightly residue - they can actually harm your home and cost you money.
Common hard water problems include:
- Stains and buildup on sinks, shower heads, and dishes
- Dry skin and hair
- Costly long-term damage to water appliances
