7 Causes of Stinky Water in Your Home and How to Fix Them

Have you ever turned on your sink or shower, only to be greeted by a terrible smell? If that sounds familiar, you’re not alone. A significant number of homeowners experience the unwelcome surprise of stinky water. Luckily, this odor often points to issues that can be easily addressed. In this post, we will explore ten surprising causes of smelly water in your home, particularly focusing on stagnant water in your water heater and pipes. More importantly, we will discuss how to remedy these issues.

1. Stagnant Water in Pipes

Stagnant water in your pipes is one of the leading causes of smelly water. When water does not flow for an extended period, it can gather minerals and debris, leading to a musty or sulfur-like smell.

When you put your house on the market, water can become stagnant in as little as a week of inactivity.

To fix this, make a habit of running water regularly throughout your home, especially in areas that are rarely used—like guest bathrooms. Flushing your pipes occasionally helps maintain water flow and prevents odors.

2. Water Heater Bacteria

Bacteria can thrive in your water heater if it is not maintained properly. Water temperatures below 120°F can cause bacteria, including Legionella, to grow. A survey found that 30% of home water heaters are set below this safe threshold, increasing the risk of odor.

To address this, set your water heater to at least 140°F for a few hours, then flush the tank. This process will help remove any sediment and bacteria buildup. Be cautious and allow the water to cool before use to avoid scalding.

3. Sulfur Bacteria

A distinct egg-like smell coming from your water may indicate the presence of sulfur-reducing bacteria. These microorganisms thrive in low-oxygen environments, such as deep wells or stagnant water. Research estimates around 1 in 50 households may experience this problem.

If you suspect sulfur bacteria, your local master plumber can inspect and come up with an effect treatment and disinfection, along with a plan to discourage sulfur bacteria from returning.

4. Corroded Pipes

Older pipes, particularly those made from iron or galvanized steel, can corrode over time. This corrosion releases rust into your water, often creating a metallic smell. Approximately 35% of older homes have plumbing that may need replacement due to corrosion.

Replacing corroded pipes is the best way to resolve this issue. Hire a professional plumber to inspect your plumbing system and identify sections that might need updating.

Often, the unpleasant smell might not stem from your water, but from your sink drains. Food scraps and bacteria can collect in the drain, leading to bad odors when water flows through. A research study found that 40% of kitchen drains contain bacteria that can cause unpleasant smells.

To clean your sink drain, mix equal parts baking soda and vinegar, then pour it down the drain, followed by boiling water. This combination can break up buildup and eliminate odors, leaving your sink fresh.

6. Lack of Maintenance

Neglected plumbing systems can lead to various issues, including smelly water. Regular inspections can identify potential problems early. A study indicates that

Schedule annual plumbing inspections to keep everything functioning properly and prevent unpleasant odors. This proactive step can save you from future headaches and costly repairs.

7. Pipe Leaks

Hidden leaks are another source of smelly water. Leaking pipes can lead to mold growth and bacteria, resulting in an unpleasant odor. Statistics show that 20% of homes experience plumbing leaks that go unnoticed.

Be vigilant about your water bill for sudden increases and watch for wet spots around your home. If you suspect a leak, contact a professional plumber promptly to assess and resolve the issue.
