Have you ever turned on the tap expecting clear water, only to see brown, yellow, or even orange water coming out? It’s not just unpleasant—it can be a little alarming. While rusty or discolored water isn’t always dangerous, it’s definitely not something you want coming out of your faucets. Understanding the cause can help you figure out the best way to fix the issue.
Is Rusty or Discolored Water Safe?
First things first—most of the time, rusty or discolored water isn’t harmful to your health. It’s usually caused by excess iron or other minerals, which aren’t dangerous in small amounts. However, it can stain your laundry, damage appliances, and, let’s be honest, nobody wants to drink or bathe in water that looks dirty. In some cases, though, discolored water can be a sign of a bigger issue, so it’s worth getting to the bottom of it with the help of a professional plumbing company.
Common Causes of Rusty or Discolored Water
Several factors can cause water discoloration, from natural mineral buildup to aging pipes. Here are the most common reasons:
1. Corroded or Aging Pipes
If your home has older metal pipes, corrosion is a likely culprit. Over time, pipes made of iron or galvanized steel can rust on the inside, and that rust eventually breaks loose, making its way into your water. This is especially common in older homes with outdated plumbing systems.
2. Sediment Buildup in Water Heaters
If the rusty water only appears when you use hot water, your water heater might be the problem. Over time, sediment and minerals settle at the bottom of the tank, and when they get stirred up, they can cause discoloration. If your water heater hasn’t been flushed in a while, this could be the reason your water looks rusty.
3. Municipal Water System Maintenance
Sometimes, the issue isn’t inside your home at all. If your local water supplier is flushing the system or working on pipes, it can disturb rust and sediment, temporarily causing discolored water. This usually clears up within a few hours once the system settles.
4. High Levels of Iron or Manganese in the Water Supply
If your water comes from a well, natural minerals like iron and manganese could be the cause of discoloration. These minerals aren’t dangerous, but they can make your water look yellow, brown, or even black in extreme cases.
5. Breaks or Leaks in Water Mains
A sudden change in water color can sometimes indicate a water main break in your area. When a pipe cracks or breaks, dirt and rust from the surrounding environment can enter the system, leading to discolored water coming from your faucets. If you notice an unexpected color change, it’s worth checking with your water supplier to see if there’s an issue in your area.
How to Fix Rusty or Discolored Water
Now that you know the possible causes, let’s talk about what you can do to get your water back to normal.
- Run the Taps – If the discoloration started suddenly, try running your taps for several minutes. Sometimes, this helps flush out sediment and clears up the problem.
- Check If It’s Just Hot Water – If only your hot water is affected, your water heater likely needs flushing. Most water heaters should be flushed at least once a year to prevent sediment buildup.
- Inspect Your Pipes – If your home has older metal pipes, corrosion might be the issue. If you notice rusty water frequently, consider having a plumber inspect your plumbing system.
- Contact Your Water Supplier – If the discoloration started after nearby construction or maintenance work, check with your water provider. They can confirm if the issue is temporary and advise on what to do next.
- Install a Filtration System – If minerals like iron or manganese are the cause, a whole-house water filtration system or water softener can help remove these particles before they reach your faucets.
When Should You Call a Professional?
While some cases of discolored water resolve on their own, there are times when calling a plumber is the best option. If you notice any of the following, it’s time to get a professional involved:
- The discoloration persists for several days despite running the taps.
- Only certain faucets are affected, which could mean a pipe issue inside your home.
- There’s a metallic taste or foul odor in the water.
- Your water pressure has dropped along with the discoloration.
- There are visible leaks or signs of rust around your pipes.
A plumber can inspect your pipes, determine whether corrosion is an issue, and recommend the best solution, whether that’s replacing sections of plumbing or installing a filtration system.
Clear, Clean Water Is Worth It
Nobody wants rusty or discolored water coming from their faucets, but the good news is that it’s often a fixable problem. Whether it’s a minor issue like sediment in your water heater or something more serious like corroded pipes, identifying the cause is the first step. If in doubt, get a professional’s opinion—clean, clear water is worth it!
