What Should You Do If Your Tap Has Rusty Water?

When you turn on the water to brush your teeth, a torrent of brown, murky muck drizzles out. Yuck! Rust-colored water isn’t usually dangerous, but it might be upsetting. If your faucet is leaking brown water, it might be due to rusted pipes, mineral buildup, or utility company activities.
Seeing rusty water flow from your home’s faucet may be a frightening experience, especially if you don’t know why. That is why we created this primer to explain why your water seems rusted and how to cure rusted water in your home’s plumbing system. If rusty pipes are the cause of your home’s water discolouration, we’ll explain what you can do about it. We want all Los Angeles citizens to have access to clean, safe drinking water.


When tap water has an overabundance of silt or minerals, it appears rusty brown, yellowish, or reddish.
Iron and manganese are the most prevalent discolouring minerals found in water. Tiny metallic deposits of these minerals can enter the water stream through a variety of natural and man-made causes. These minerals may also be to blame for any unpleasant tastes or odours in your water.
While these elements are not dangerous to people, the presence of manganese and iron in water may cause your tap water to smell or taste strange. To ensure that nothing else is wrong, a plumber can test the water quality in your house.


It depends on the minerals in your water, but most likely not. The authorities control the treatment of pollutants in drinking water based on primary and secondary criteria. The major rules include hazardous pollutants such as lead and arsenic. If pollutants in a water supply surpass a maximum contamination level, the water is (generally) not distributed to the public.
Secondary rules address pollutants such as iron and manganese. These pollutants are not harmful to health, but they have an unpleasant taste, odour, or appearance and may stain garments or create skin rashes. Although public water systems are required to test for major pollutants on a regular basis, secondary contaminant testing is sadly discretionary.


Is rusty water unhealthy for your hair? is another often asked issue. While drinking or bathing in high mineral water is not harmful to your health, it is not good for your hair. Furthermore, hard water might make it difficult for soap to lather effectively on your skin, requiring you to work harder to become clean.
Brown water from your faucet might be caused by any of the three circumstances listed below:

1. If all of your water (hot and cold) turns brown all of a sudden:
A rupture in a city-operated water main or fire hydrant might cause a sudden change from clear to rusty water. Because most of America’s plumbing infrastructure is old, water main breaches that leak silt into the water supply are common.
When utility providers do line maintenance, the water is turned off for brief periods of time. When the water is switched back on, some deposited sediment may be present. To resolve the issue, run your faucet for a few minutes.
There might be internal causes for the change as well. Your water heater or water supply pipes have rusted or corroded, and the brown water coming from your faucet is the first indicator of these changes.
2. If just your hot water is discoloured:
Sediment or rust may have accumulated in the tank of your water heater. Your plumber will be able to determine the cause of this.
3. If you’re getting brown water from your cold tap but just from certain faucets:
The issue is most likely with a specific water supply line. Home plumbing clogs and corrodes with time, especially if your water is mineral-rich.


You know where to begin now that you know what caused your rusty water discoloration in the first place:

If all of your hot and cold water turns brown at once:

Contact your water company. Something likely happened to a water main or a local fire hydrant. It’s also likely that the city is performing pipe repair and accidentally stirred up some silt. They should be able to tell you when your water will clean up and what they’re doing to resolve the issue.
After the utility work is completed, run your faucets for a few minutes until you no longer see orange water pouring out of them. Brown water in toilets should go away after a few flushes to replenish the water supply.

If all of your hot water is discoloured:

Try draining and cleansing the tank of your water heater. Rusty hot water is frequently the consequence of debris that has accumulated over time. In any case, draining and flushing your tank twice a year is a smart idea. Sediment accumulation is not just harmful for your water; it is also one of the leading causes of water heater leaks.
Check to make sure your anode rod hasn’t disintegrated. To lengthen the life of your water heater tank, this rod collects harmful minerals in the water. Your anode rod will degrade after around 5 years, and your local plumber can replace it for you.
If you cleanse the tank or have a modern water heater and your hot water remains discoloured, you may have a larger issue. Diagnosis the problem by contacting a competent plumber. Excessive sediment buildup can permanently harm your water heater or, in rare and extreme cases, cause it to explode!
If your cold water is only discoloured from a few taps, begin by running those faucets at full pressure for several minutes, or until the water clears entirely. A little quantity of rust may occasionally dislodge from the inner walls of a pipe and infiltrate the water supply. If the issue is small, merely running the water should remove the rust and clarify the water.
However, if your water still looks rusty after running it, or if the problem returns immediately after you flush the rust, it might be due to rusted pipes. When there is too much corrosion or rust on the pipe walls of your home’s water supply pipes, minerals seep into the water. You will continue to have brown water from your cold tap until the problematic pipes are replaced.
If you have corroded or rusty pipes, you should get them thoroughly cleaned or replaced as soon as possible, before they do further damage. Corroded pipes can cause blockages, leaks, and fractures in your water line.
