Discolored water is a common plumbing problem that often scares people. But let me give you a reason to breathe a sigh of relief: Just because your tap water isn’t clear, doesn’t mean that it’s harmful. However, it does mean that something is wrong with the domestic water system.

(And remember, lead in your water supply IS harmful!)

It’s important for all adults to take notice of our tap water’s color, smell and taste, as well as other details of our water pipe systems, especially if you own your home.

So if not all discolored water is dangerous, what does the discolored water mean? And how can you tell if your water is dangerous for consumption? We break it down for you:

 

 

 

Yellow or Semi-Red Water – If your tap water is clear at first but then changes to yellow or rusty color when it stands, then there is ferrous iron in the water, which means the iron that is leaching into the water has not rusted or oxidized yet. This is not harmful to our health, but note that this type of iron cannot be filtered out of your water.

Rusty Reddish Water– This color water means that ferric iron (oxidized iron, also known as rust) is leaching into your tap water. While this is not toxic, it is not easily filtered out and can stain sinks, bathtubs, etc.

Greenish Blue Water (dangerous) – If you’re seeing this color water, find out if your water pipes are copper or if you water system has brass fittings. If so, this water discoloration is a result of copper leaching and the water is dangerous for consumption. Please contact a plumbing company, like us, immediately. 

Green Water (dangerous)– Seeing green water means algae buildup has occurred in your plumbing system. Please contact a plumbing service company, like us, to correct the issue.

Black Water (could be dangerous)– This could be from manganese, which is harmless, or it could be from mold or mildew. Therefore, it’s best for you to call a plumbing company, like us, to check it out.

Pink Water – Your local water authority may have accidently added too much potassium permanganate to the water supply if the water looks pink. However, it is not harmful to human’s health.

Purple Water (dangerous)- A harmful amount of potassium permanganate was probably added to the water supply to cause it to turn purple. It’s best for you to inform the water authority about it immediately.

White or Cloudy Water– This mean extra air is trapped in or moving through the water. If you put some of the cloudy tap water into a glass. Bubbles should rise and the cloudiness should dissipate.

Clear Water (could be dangerous)– Lead does not have a taste or smell and it cannot always be seen in drinking water. That clear, clean-looking water coming out of your tap water may have dangerous levels of lead in it and the only way to know for sure is to have your tap water tested.

 

More info about Rusty Water:

Iron can get into the water supply due to iron being in the soil or if the pipe system contains iron. Iron in plumbing systems deteriorates over time due to the chemistry from the water and oxygen. The natural by-product of corroding iron is rust, which breaks off in the pipes and goes to the tap, causing the water to be discolored and usually revealing a rusty color. Keep in mind that the EPA says iron in water is not toxic and does not have a direct impact on health.

 

 

So now what?

If you’re located in southeast Texas, please give us a call or send us an email with your concerns or questions. We’d love to help!

Sometimes discolored water problems have easy fixes and sometimes they don’t. The best way to alleviate or prevent discolored water (as well as pinhole leaks, under slab leaks, low water pressure, bring lead leaching into compliance and other problems) is to protect your galvanized or copper water system with a safe (tested and certified to NSF Standard 61), internal pipe epoxy barrier coating. The patented ePIPE epoxy barrier coating is a cost-effective and better value alternative to a whole house repipe. Learn more about ePIPE by clicking here.
