Why test your water?

The importance of your home’s water quality goes beyond just the taste.

Putting solutions in place to provide superior quality water promotes better wellness, protects your home’s plumbing and appliances, and can even help reduce environmental impact.

While some contaminants can cause foul tastes or odors, many others can’t be seen, tasted or smelled.* That’s why professional water testing is so important. Your local Culligan experts know firsthand about common water issues in your area. With a free, in-home water test, they can check for a variety of problems, with results in 30 minutes or less. Your Culligan expert may also send your water test to our IL EPA-certified lab, which can test for many other types of water contaminants including lead, PFAS, bacteria, and others.

When to test your home’s water

If you’ve moved

The quality of your water can vary depending on your water source and other environmental factors. A home water test can help determine what you’re dealing with and how to protect against future problems. If your new home has a water treatment system already, you should still test your water to ensure it is effectively addressing all current issues.

If you have a private well

Unlike municipal water systems, private wells aren’t regulated, so safety is the homeowner’s responsibility. Water testing can help uncover common issues like iron, sulfur and bacteria. It can also detect high levels of minerals—such as calcium and magnesium—which cause hard water problems such as dry skin, dry hair and buildup on pipes and faucets.

If you have odor or taste issues

Between coffee at breakfast and pasta for dinner, there are plenty of ways you use water in the kitchen. Water with an unpleasant odor or taste could make your culinary experience anything but enjoyable. For example, iron is known to leave a metallic aftertaste, while chlorine can create an unpleasant bleach smell.

If you have spots, stains, or buildup

Common indicators of water problems also include unsightly stains in your sinks, buildup on your showerheads and spots on your dishes. If left unresolved, water issues can cause long-term damage to your water-using appliances, costing you more money and headaches.

What Culligan tests for

Your free home water test can reveal a variety of potential problems. Depending on where you live, your water source and any specific concerns you may have, your Culligan expert may also recommend sending in your sample for more in-depth laboratory testing.

Water hardness

Hard water is caused by the presence of excess magnesium and calcium, which are naturally found in groundwater. These minerals build up and can damage hair, skin, pipes and water-using appliances; they also cause unsightly, hard-to-clean buildup on sinks, showers and dishes. A hard water test can help to determine whether your home could benefit from a water softening system.

Total dissolved solids (TDS)

Total dissolved solids include metals, minerals and salts, which at high levels can make your water look cloudy and have a bitter, metallic taste. They can also make your water hard, corrode plumbing, reduce the lifespan of water-using appliances, and give water a salty or bitter taste.

Nitrates, iron and hydrogen sulfide

High levels of nitrates can have negative health effects and are difficult to detect without water quality testing. Iron is often found in well water and can damage appliances, pipes and fixtures. Hydrogen sulfide produces a rotten-egg, sulfur smell and is also common in well water homes.

Chlorine and pH

Chlorine in your water is not typically a health concern but often results in unpleasant tastes and smells. If the pH level of your water is too high or low, it can negatively affect the taste, water pressure and feel of the water.

More comprehensive testing

Where requested or recommended, Culligan’s IL EPA-certified lab can perform water tests for nearly 50 different potential issues, including PFAS, lead, copper, bacteria, arsenic, mercury and more.

Water quality testing FAQs

What is water quality?

Your water quality is a quantitative and qualitative measure of what is in your water and how that can affect your home and family. Whether your water supply comes from the city or a private well, your tap water may contain contaminants such as dissolved minerals and metals, chemicals, bacteria and more could be present, affecting not only the taste, smell and feel of your water but also your health. Water testing is an important first step toward ensuring your have water you can trust.

Is my water safe to drink?

If you have city water, your local water supplier is already taking steps to make your water safer. However, unfiltered tap water may still have problems. Some contaminants can make their way into your water as it travels from your city supply to your home, or through your own pipes. There are also emerging water contaminants that are not yet regulated. At the same time, even safe water may have contaminants that can affect the smell and taste or damage plumbing and appliances. A water quality test can reveal what is in your water and if it is safe to drink.

What’s in my tap water?

Common tap water issues vary by region, water supply, and whether you have city or well water. Hard water, which means high levels of magnesium and calcium, is common in well and city water. Man-made chemicals like PFAS can be present in both water sources as well.* If your water is supplied by a municipality, it may have chlorine and fluoride. High levels of iron and/or hydrogen sulfide are common in well water; arsenic or nitrates may also be issues depending on where you live. Professional water testing is the best way to get a comprehensive picture of what is in your tap water and make sure you can put the right treatment solutions in place if needed.

How can I test well water?

Well water testing is especially important because private well water is not regulated or treated by the government or local municipalities. As with city water, the best approach is to work with a professional who knows what to test for and can recommend the right well water treatment solutions. It’s recommended to test yearly for problems like bacteria, nitrates, pH and TDS, but you should also test any time you notice changes to your water quality or disturbances near your well such as flooding or construction. Testing is recommended as well when you replace or repair any part of your well, or if there are known problems with groundwater in your area.

How often should water be tested?

How often you should get a home water test depends on the source of your water supply. Private well water should generally be tested annually. Municipal water homes should also be tested, particularly if issues are detected like hard water buildup, odors or discoloration, or if you have concerns about specific contaminants or your water quality overall. If you notice any changes to your water quality, have just moved to a new home, or experience irritated skin or dry hair, a water test is recommended.
