Why Is My Water Turning Brown? A Troubleshooting Guide

Few things are as unsettling as turning on a faucet and seeing brown water flow out. While discolored water doesn’t always mean there’s a serious problem, it’s a clear sign that something in your plumbing or water supply needs attention. If your home relies on a private well, the issue may be connected to your well system or pump. Here are some of the most common reasons water turns brown—and what you should do about it.

Rust and Sediment in the Water Supply

One of the most common culprits behind brown water is rust. Over time, iron pipes corrode, releasing rust particles that tint the water brown, orange, or even reddish. This can happen in older homes with galvanized plumbing or in community water systems when utility crews flush out lines. While a small amount of rust isn’t typically harmful, it can stain laundry, dishes, and fixtures.

Sediment buildup is another possible cause. In well systems, minerals, sand, or silt can accumulate at the bottom of the well. When disturbed—either by heavy use, seasonal shifts, or pump problems—these particles can enter the water supply and cause discoloration.

Well Pump Issues

If your home uses a well, a malfunctioning pump can play a direct role in brown water. A pump that isn’t positioned properly or is sitting too low in the well may begin drawing up sediment along with water. Similarly, if the pump is wearing out, it may not be able to maintain proper water pressure, stirring up particles that then make their way to your faucets.

In some cases, a failing pump can allow contaminants from the surrounding ground to seep into the water. This not only leads to discoloration but can also affect the overall safety and taste of your drinking water.

Changes in the Water Table

Homes that rely on well water are directly impacted by the condition of the local water table. Periods of drought, heavy rainfall, or seasonal changes can alter the water table and stir up sediment inside the well. If your brown water coincides with recent weather changes, this could be the cause.

Plumbing System Problems

Sometimes, the source of the problem isn’t the well or the pump but your home’s plumbing. Older pipes, especially those made of cast iron, are prone to corrosion. As rust builds up inside the pipes, it can flake off and mix with your water, leading to discoloration. If the issue only appears in one faucet or one area of the home, the problem may be localized to that section of piping.

What to Do If Your Water Turns Brown

If you notice brown water in your home, it’s important not to ignore it. First, run cold water for several minutes to see if it clears up—it may simply be sediment stirred up by nearby maintenance or temporary conditions. If the problem persists, especially if you rely on a well, schedule an inspection with a licensed plumber or well specialist. They can check the pump, test your water for contaminants, and identify whether repairs or adjustments are needed.

Brown water is a warning sign that something isn’t right with your plumbing or well system. Whether it’s caused by rust, sediment, or a failing pump, acting quickly can protect your water quality, your health, and your home’s plumbing. Regular maintenance and water testing are the best defenses against unexpected surprises at the faucet.
