What Causes Black Water From a Faucet?

Seeing black water come out of a faucet can be an alarming experience, and maybe even a scary one for some people. Seeing brown, discolored water usually isn’t something to be overly worried about, and there are several reasons why this can happen.

Seeing black water coming from your faucet can be due to mineral deposits, rusty pipes, mildew growth, sand particles, or an old filtration system.

Why Is the Water Coming From My Faucet Black?

Mineral Deposits

A build-up of mineral deposits is one of the reasons why you might be experiencing black, brown, and discolored water. A couple of the more prevalent minerals that you’ll see in the water are manganese, magnesium, and iron.

Mineral oxidization occurs when minerals meet oxygen. This results in things becoming discolored, and that’s why you’ll see your water turn black.

If this is the cause of your dark water, then you don’t need to become overly worried because these minerals aren’t harmful to humans. You typically won’t want to be brushing your teeth with this type of water, though.

How Do You Clean Up Black Water From Minerals?

If minerals are the cause of your black water, all you have to do is get a proper filtration system or water softener installed in your home. In most cases, this will prevent the black water from recurring.

Rusty Pipes

Sometimes rust is the cause of water becoming discolored. The color of rusty water is usually brown, red, orange, or black. When rust oxidizes, it turns to a dark color, and that’s why you’ll notice it when it makes its way out of your faucets.

If rusty pipes are the cause of your dark water, you’ll typically see tiny particles coming through your water.

How Do You Clean Up Black Water From Rust?

Rusty pipes should be replaced right away if that’s the cause of your black water. If you can’t replace them completely, you’ll want to replace certain sections of them.


Mildew is another culprit of discolored water. If you think that mildew might be to blame for your black water, you’ll want to get a plumber in there to look at things as soon as you can. Drinking mildew in your water is extremely unhealthy.

Sand Particles

You might notice the water coming out of your faucets being black due to sand or clay particles in it. If this happens to you, you’ll want to get a liner installed to prevent it from happening. You can also get a screen installed if the current one in your well isn’t doing its job properly anymore.

Outdated Filtration System

A lot of filtration systems on the market use granular activated carbon because of its ability to absorb tastes and odors from the water that isn’t filtered.

As time goes on, you might notice particles from the granular activated carbon getting into your water and faucets. If this is the cause of your darkened water, all you must do is replace the cartridge and your water should start to become clear.

Is Black Water Dangerous?

In most cases, black water isn’t a huge cause for concern, but it all depends on what the cause for the black water is. If it’s due to rusted pipes or mildew, then those are cases where it can be dangerous.

If the black water is due to just an over-abundance of minerals in your water, then that’s not something that raises a huge red flag. Either way, you’ll want to address your black water concerns so you can begin to drink clear water again.

How Do You Get Black Gunk Out of Faucet?

There are several ways to get black gunk out of your faucet:

Figure Out the Finish of Your Faucet

Before jumping to certain quick fixes, you’ll want to be aware of what type of faucet you have. Knowing this will determine what cleaning solutions you’ll be using on your faucet. Try checking with the manufacturer of your facet to ensure you’re using a compatible product.

Dish Soap and Water

If there isn’t a great deal of black gunk on your faucet, try just using simple dish soap and warm water mixture. Get a cloth and give the faucet a good scrub.

White Vinegar

Many people turn to white vinegar if dish soap and warm water doesn’t work. All you must do is get about half of a cup of white vinegar to half of a cup of hot water. Ensure that you test out the mixture on a small portion of the faucet before using it on the entire thing.

Toothbrush And Baking Soda

Using baking soda and a toothbrush is a good way to get rid of black gunk stains on your faucet.

Can You Drink Black Water?

Blackwater is, in most cases, safe to drink, but that also depends on the cause of your black water. The most common cause of black water is excessive minerals in it. If that’s the cause in your situation, then you should be fine with consuming it.

If the cause of your black water is due to mildew, then that’s another story. You never want to be drinking water that has mildew in it. This could lead to health issues, and you’ll want to address the situation promptly.

What Does Black Water Indicate?

Blackwater usually indicates one of several possible things:

  • There could be mineral deposits in your water
  • There could be a rusty pipe that your water travels through
  • There could be mildew in your water
  • There could be sand or clay particles in your water
  • You could be using an outdated filtration system

What Is Black Water Damage?

When water damage to your home results in mold and other types of contamination that could lead to serious health consequences, that is known as black water damage. There are three categories of black water damage.

Category 1

The category 1 level of black water damage is damage that usually starts from inside of the house. An example of this would be a toilet overflowing in the bathroom.

Category 2

Category 2 black water damage is a little more serious and refers to damage that is a little more severe. Things like drywall, carpet, drapery, and furniture damage are included in category 2.

Category 3

Category 3 refers to water getting into a home from a source outside the home. An example of this is a sewage line.

No one wants to be drinking bottled water that has a brown color in it. Water should always be clear, but sometimes certain circumstances occur that discolor it, making it less appealing to drink and bathe in. Figuring out the root cause of it is the first step in clearing up the problem.
