What Issues Your Discolored Water Indicates


Discovering discolored water can be quite a shock to any homeowner. While some variations of colored water are technically safe to drink, any shade besides crystal clear can be a cause for concern. Read on to learn more about discolored water and how to address it.

Reddish-Orange Water

If you notice red or orange tones in your water, rust is likely the culprit. This often occurs in older houses where the pipes are made from galvanized iron or steel. This type of discolored water can not only stain clothes you wash, but also change the taste or color of your food. While this type of water is not necessarily a health threat, your pipes will eventually need to be replaced with newer, non-rusting metal.

Yellow Water

Sometimes, yellow water occurs as a result of small amounts of sediment or rust, but it commonly indicates a problem within your city's water distribution center. If the yellow flow is only affecting your cold water, this could mean that your city is conducting a flush - an annual procedure to clear major plumbing lines of built-up sediment. If the problem persists, check with your local water distribution center to find out why the yellow water is persisting.

Green Water

Green-toned water usually indicates one of two issues: algae buildup or worn copper pipes. An algae bloom is often caused by a blockage or buildup somewhere along your pipeline. Most variations of algae pose a serious health risk, so use caution. Contact a professional plumber to diagnose where the blockage is coming from and clear your system of this issue.

If you have copper pipes or plumbing elements, you may notice stains along with greenish water as the elements decay over time. Copper in your water is considered a health hazard, as ingesting large quantities can lead to kidney and liver problems. Call a plumber to discuss having these elements replaced as soon as possible.

Black Water

Black water is a telltale sign of mildew, which is unsafe to drink and should be addressed immediately. It may also indicate deterioration of plumbing parts or sediment buildup. If you notice black water for any reason, avoid ingesting the colored water and contact a professional to investigate.

Water discoloration can also stem from pollution or excess sediment, both of which are more common after a storm or natural disaster. If you need help addressing a rainbow of troublesome tones in your water supply, call David Gray Plumbing at (904) 605-8190 or visit our website at
