Why is Your Water Discolored?

Tap water in your Tucson home can sometimes become discolored or appear cloudy. In some cases, it may appear to have small particles in it. Old houses and houses that have been vacant for an extended period often have the problem of discolored water.


Usually, the color is not easy to see unless the water is collected in a toilet bowl or bathtub. Usually, the color will go away after the water has been running for a few minutes. There are a number of potential causes of water discoloration. The color of the water is often an indicator of the cause. Here are three of the most common causes of water discoloration.

1. Yellow and Red Water

The most common type of discoloration is yellow or red water caused by rust. The degree of oxidation determines the color. Rust in your water could originate from your municipal water supply, your pipes or the water heater of your Tucson home.

If the rust only shows up when using cold water, then the municipal water supply is the most probable cause. Other signs that this is the case include sudden discoloration or discoloration that appears at all faucets.

Rust from one faucet or that appears every morning may indicate that the problem is your plumbing. If this is the case, you will need to replace any rusted pipes. If your water heater is putting out yellow water, this may be due to the accumulation of sediments in the bottom of the tank or due to iron bacteria. Both issues may be solved by flushing the water heater tank.

Rust is not a threat to your health; however, it can stain clothes. Simply rewash your clothes when the water clears up. Avoid using bleach as this will make the stains permanent.

2. Blue or Blue-Green Water

Brass or copper plumbing may produce blue-green water. This type of discolored water can cause serious health issues, which means that the problem needs to be fixed as soon as possible. Blue water in your faucets can also be caused by disinfectant in your toilet tank. Water from a leaking toilet tank may be mixing with your water supply.

3. Pink Water

A type of bacteria often found in well water causes this discoloration. It is not harmful and stains are easily cleaned.
