Water is essential for daily life, but even clear, odorless water can harbor hidden contaminants that affect your health and home. A professional water test can reveal problems that are otherwise invisible. Here are 10 signs that indicate it might be time to schedule a test with FONTUS Water Treatment.

1. Unusual Taste or Odor

If your tap water has a strange metallic, sulfur-like, or chemical taste or smell, it could indicate contamination. Even subtle changes should not be ignored, as they can signal potential health risks.

2. Discoloration or Cloudiness

Cloudy, brown, or yellow water is a clear warning sign. Sediment, rust, or other particles can damage plumbing and appliances while signaling water quality issues.

3. Staining on Fixtures or Laundry

Mineral buildup or contaminants in water can leave stains on sinks, toilets, and laundry. Persistent staining is a signal that your water may need professional testing and treatment.

4. Health Symptoms

Unexplained skin irritation, digestive issues, or other health symptoms can sometimes be linked to water quality. A professional test can help determine if contaminants are the cause.

5. Presence of Lead or Old Plumbing

Homes with older plumbing may have lead pipes or solder that can leach into drinking water. Testing is essential to ensure the water is safe, especially for children and pregnant individuals.

6. Hard Water Issues

Hard water can cause scale buildup in pipes, appliances, and water heaters, reducing efficiency and lifespan. A water test can confirm hardness levels and guide treatment options.

7. Recent Changes in Water Source

If your home has a new well, municipal water line, or water treatment system, testing is crucial. Changes in water source can introduce new contaminants.

8. Strange Sediment or Particles

Floating particles or sediment in water can indicate contamination or pipe corrosion. A water test identifies the cause and ensures your water is safe.

9. Nearby Environmental Risks

If your home is near agricultural operations, industrial sites, or construction, your water may be exposed to pollutants. Testing helps detect potential risks early.

10. Peace of Mind

Even if there are no obvious signs, testing your water periodically provides reassurance. Knowing your water is clean protects your health and your home.
