6 Reasons Your Tap Water Is Cloudy

Turning on the tap and seeing cloudy or milky water can be a bit alarming. While it’s often harmless, cloudy water can be a sign that something’s wrong with your plumbing or water supply. Whether it's a temporary issue or something that requires professional attention, understanding the root cause can help you decide when it's time to call a plumber or schedule a plumbing repair service. Here are six common reasons your tap water might be cloudy—and what you can do about it.

1. Air Bubbles in the Water

One of the most common causes of cloudy tap water is air bubbles. When air gets trapped in your plumbing system—usually after maintenance or a recent change in water pressure—it can cause the water to look cloudy or milky. The good news? This type of cloudiness usually clears up on its own after a few seconds in a glass. If it does, it’s just air and nothing to worry about.

2. Hard Water and Mineral Content

Hard water is water that has a high concentration of dissolved minerals like calcium and magnesium. While not typically harmful to your health, these minerals can cause cloudiness and leave deposits on faucets and dishes. Over time, hard water can lead to buildup in pipes and appliances, which may require a plumbing repair service to address. Installing a water softener can help reduce these issues.

3. Sediment in the Water Supply

If your water comes from a well or a municipal source with aging infrastructure, sediment can occasionally find its way into your tap water. Dirt, sand, and other particles can make your water appear cloudy. If sediment is the culprit, it’s a good idea to have a plumber inspect your plumbing system and possibly install a filtration system to keep your water clean and clear.

4. Water Heater Issues

If the cloudy water only appears when using hot water, your water heater may be to blame. Sediment buildup inside the tank can mix with the water and cause cloudiness. Regular maintenance, including flushing the tank, can help avoid this problem. If the issue persists, it might be time to have a plumbing repair service take a closer look at your water heater.

5. Pipe Corrosion or Rust

Old or corroded pipes can release rust and other particles into your water, leading to discoloration and cloudiness. If you notice a metallic taste or orange and brown tints in addition to cloudiness, corroded pipes may be the issue. This is not something to ignore, as it can lead to leaks or pipe failure. A licensed plumber at Mr. Rooter Plumbing can inspect your pipes and recommend the best course of action, which may include pipe replacement.

6. Municipal Water Supply Maintenance

Sometimes, the problem isn’t in your home at all. Municipal water suppliers occasionally flush their systems or perform repairs that stir up sediment and introduce air into the lines. This can lead to temporary cloudiness in your tap water. Typically, this will clear up on its own within a few hours. If the issue continues for more than a day, it’s a good idea to contact your water supplier or call a plumber to rule out problems in your own system.

When to Call a Plumbing Repair Service

While cloudy water isn’t always a cause for concern, it’s important to pay attention to changes in water quality. If the cloudiness persists, or if it’s accompanied by a bad smell, odd taste, or discoloration, it’s time to call a plumbing repair service. A professional plumber in Oakhurst, NJ at Mr. Rooter Plumbing can identify the root cause of the issue and recommend the right fix—whether it’s installing a filtration system, replacing corroded pipes, or flushing your water heater. Keeping your water clear and safe is essential for everyday life. Don’t ignore the signs—when in doubt, it’s always best to let a professional take a look.
