Here’s Why Your Water Is Discolored — and What You Can Do About It

When you turn on the tap, is the water brown, yellow, or reddish? Water is supposed to be clean and colorless, so when it isn’t, something is off. Mr. Rooter Plumbing can help. Whether it’s rust, sediment, or something deeper in the system, it’s never something to ignore. Read on to find out what’s really causing that strange tint and what you can do to get your clean water back.

Rust, Sediment, and Pipe Corrosion

The most frequent cause of discolored water is corrosion inside aging pipes. Metal pipes made from galvanized steel or iron will start to degrade, and as they corrode, tiny flakes of rust and sediment break off and mix into your water. This is most noticeable when the tap has been off for a while or after work has been done on the water main. Municipal water systems that seem reliable can still stir up sediment during repairs or after changes in pressure. Your water might suddenly appear discolored after a city crew’s been on your block. It might also happen after seasonal shifts that increase the strain on older plumbing. If your home has old piping, you may also notice uneven water pressure or strange smells alongside the discoloration. These are signs that the pipes are deteriorating but may also be harboring bacterial buildup. Calling a professional plumber for an inspection is the fastest way to rule out major damage and prevent future leaks or health concerns.

Water Heater Trouble You Can’t See

If your hot water is the only source of discoloration, the problem likely lives inside the tank. Sediment collects at the bottom of the tank, especially in areas with hard water. The sediment can turn into a muddy mix that tints your water brown or yellow when it’s heated. Water heaters also have an anode rod designed to prevent rust, but once it corrodes completely, the tank itself may begin to rust. You won’t always hear or see this happening, but you’ll eventually notice your water changing color or see signs of leaking. Routine maintenance, including flushing the tank once a year, can help extend the life of your water heater and avoid this type of discoloration. If it’s already too late, you’ll want to replace the unit before the rust builds up and creates more damage.

City Water vs. Well Water

Whether you’re on a city system or a private well can influence the likely cause and solution for discolored water. Municipal systems are typically treated for safety, but they can still introduce problems when pipes burst or lines are replaced. Temporary discoloration after utility work is common, but if it persists beyond a day or two, it could be a sign that your home's pipes are the source. Well, water can have high levels of iron, manganese, or other minerals that cause water to look orange, yellow, or black. These aren’t always dangerous to your health, but they do stain clothes, damage fixtures, and leave behind an unpleasant taste. The best way to stay ahead of these issues is routine testing. For well owners, annual water testing is extremely important. If your water test shows high mineral content or bacterial presence, filtration is the next step. A proper water filtration installation that’s customized to your specific water source can remove iron, sediment, and other discoloring agents before they reach your faucet. It's one of the smartest upgrades you can make if you're tired of bottled water and appliance repairs.

What You Can Do Now to Get Clear Water Again

The first step is to identify whether the discoloration is affecting all your water or just certain fixtures. If it’s isolated to one faucet or bathroom, the problem might be localized. If every tap shows signs, you’re likely dealing with something deeper in the plumbing. Let your water run for several minutes to see if it clears. If it does, and you haven’t used water for several hours, sediment may have just settled in the pipes. If it doesn’t, or the water gets worse, it’s time to act. Next, consider the age of your plumbing. Older homes with galvanized pipes are prone to rust. If you’re unsure what your pipes are made of, a plumber can tell you during a routine inspection. They may recommend replacing sections of corroded pipe or installing a filtration system to reduce the effects. Don’t forget your water heater, either. If it’s more than 10 years old, hasn’t been flushed regularly, or is producing only discolored hot water, it may need repair or replacement. In some cases, temporary discoloration caused by municipal work will clear on its own, but if you see flakes, smell sulfur, or your water feels slimy, don’t wait. These could be signs of bacterial growth or chemical imbalances that require an immediate plumbing repair service. Whatever the cause, treating discolored water protects your appliances, fixtures, and your family’s health.
