You might wonder why there would be rust in the hot water heater, and we’re here to help you understand why it happens and what to do if you find rust in your hot water. You can rely on Wickliffe's water heater repair to resolve the issue by calling Formica Plumbing & Sewer Co. at 440-485-3850 today.


Signs of Rust Forming in the Water Heater

The most obvious sign of rust in the hot water heater is watching rusty water with a red or brown tinge flow out of your faucets. While finding rust in your hot water may be startling, it is not necessarily hazardous to your health, but it is a clear sign that your water heater needs expert attention as soon as possible.


However, discolored hot water isn’t the only sign that can indicate a problem inside your hot water tank or an issue with the tank itself. You might suspect that there is rust in the hot water heater if you see either of the following signs:


  • You use far more gallons of water each month than usual due to potential leaks from the damage corrosion causes to the system and delivery lines.
  • You discover fluctuations in the temperature while using the hot water without adjusting the control knob.
  • You notice a decrease in heating efficiency or a reduction in how long you can use the hot water.


These signs indicate a need for professional hot water heater maintenance services like repair or replacement, even if rust isn’t the direct cause of the problem. Only a qualified technician will be able to appropriately diagnose the issue and provide the necessary solution.


What Causes Rust in the Hot Water Heater?

So, what causes rust to begin showing up in your water heater? The primary cause of rust in the hot water heater is a failure of the anode rod. This rod helps control sediment buildup in the tank by attracting the corrosive materials of the hard water in the supply line to itself instead of allowing it to block other parts.


Over time, this rod will need replacement, which is a relatively simple repair for a skilled plumbing crew. In many cases of rust-colored water, your technician will only need to replace the rod to repair the issue. In some cases, the water heater may simply be too old to continue working properly, requiring a complete replacement of the system.


If your water supply has a high level of minerals, you may need to take a few more proactive steps to prevent and reduce water heater issues, including annual tank flushing services or installing a water softener. Learn more about water heater safety so you can take the appropriate precautions and protect your home.


Some households may rely on older water supply lines that can also contribute to discoloration of water in both the cold and hot water coming from the faucet. Trust your local plumbing technicians to determine the most likely cause of rust-colored water in your home.


Where Else Can Rust Develop on the Water Heater?

In addition to potentially discovering rust in the hot water coming out of your faucets or shower heads, there are other areas where rust can develop that you should take note of. We review the most common areas where you might find rust on or around your water heater system below.


Water Heater Exterior

The water heater tank’s exterior can begin to degrade over time from exposure to moisture which contributes to the oxidation of metals. Because the tank contracts and expands frequently, any loss of structural integrity can lead to a complete breakdown of the tank.


If rust begins to develop around the surrounding shell of the water heater, your home may be at risk of water damage from leaks when the tank becomes too brittle to accommodate the temperature change as the tank fills with cold water and heats up.


You will need to take fast action and speak with a water heater expert to schedule a replacement water heater installation service to prevent damage to your home at the first signs of rust on the outer body of your water heater.


Heat Exchanger

The heat exchanger is another vital part of the water heater and consists of a coil that makes it possible to heat the cool water within the heating tank. Damage to this part from rust and corrosion can contribute to the release of combustible gases that pose a danger to your health.


Only a trained and fully-equipped plumbing technician can diagnose and repair this issue after a detailed inspection of the water heating system in your home.


Pressure Relief Valve

Every hot water heater includes a safety feature in the event that your system needs relief from pressure. This feature is also essential for the proper flushing maintenance procedure. If rust begins developing here, it may severely compromise the safety of the tank during daily operation.


Take action quickly to prevent this issue from causing harm to your home and complicating your lifestyle. Rely on the team at Formica Plumbing & Sewer Co. to provide knowledgeable plumbing professionals that will handle every detail of a water heater replacement service for you.


Professional Repair for Hot Water Heaters

The water heating system depends on both a pressurized water supply and a fuel source, which both require advanced knowledge and specialized tools to fix the problem safely. The professionals at Formica Plumbing & Sewer Co. is ready to provide the water heater services you need.


With this information, you will know what to do if you ever find reddish or brownish water flowing from your household faucets. When your water heater begins showing any sign of rust, it’s time to contact a reliable plumbing company for expert water heater replacement or repair services.

Dealing with a broken water heater can feel like trying to navigate a ship in stormy seas. But don't worry, you can take control of the situation with some straightforward steps. From checking the power supply to flushing the tank, these smart tips will help you get your hot water back in no time. But what if the problem is more complex than you think? Let's explore what you can do next. Identify the Symptoms of a Malfunctioning Water Heater Have you noticed anything unusual with your water heater lately? If you're experiencing inconsistent water temperatures or lukewarm water when you need hot water, it's a clear sign that something's wrong. You might also hear strange noises, like popping or humming, which could indicate sediment buildup or other issues inside the tank. Additionally, check for any leaks around the base of the unit; even small puddles can signal a serious problem. Discoloration in your water, like a rusty or brown tint, suggests corrosion or a failing tank. Finally, if you smell gas or a strange odor, it's essential to act immediately and contact a professional. Regular inspections can help detect corrosion issues early and prevent more significant problems. Recognizing these symptoms early can save you from costly repairs down the line. Stay vigilant and trust your instincts; if something feels off, it probably is. Don't hesitate to reach out for help if you need it. Check the Power Supply and Circuit Breaker Before you get into any repairs, check the power supply and circuit breaker first. Make sure the power connection is secure and examine the circuit breaker for any issues. If the breaker's tripped, simply reset it and see if that solves the problem. Additionally, ensure that your water heater is not older than 10 years, as older units are more prone to issues . Inspect Power Connection When your water heater isn't functioning, the first step is to inspect the power connection to confirm everything's in order. This confirms that power is flowing properly to your unit. Here's what you should do: Check the power cord – Make sure it's securely plugged into the outlet. Inspect for visible damage – Look for frayed wires or burns on the cord. Verify the outlet – Test it with another appliance to confirm it's working. Look for tripped GFCI outlets – Reset any that may have tripped, affecting the power supply. Examine Circuit Breaker Checking the circuit breaker is essential in diagnosing your water heater issues. Begin by locating your electrical panel and inspecting the breakers. Look for any that are in the "off" position or have a tripped appearance. If you find one, it could mean your water heater isn't receiving power. It's vital to guarantee that the breaker supplying power to your water heater is functioning correctly. If it's not tripped, you might still want to reset it by turning it off and then back on. Be cautious and check for any signs of damage or wear on the breaker itself. If you're unsure about the process, don't hesitate to consult a professional for assistance. Your water heater needs reliable power to function efficiently. Reset Tripped Breaker After inspecting the circuit breaker, you may find that it's tripped, which can prevent your water heater from getting power. Resetting it's often a simple fix. Here's what you need to do: Locate the breaker panel – It's usually in a basement, garage, or utility room. Find the tripped breaker – It'll be in the "off" position or in the middle. Reset the breaker – Flip it fully to the "off" position and then back to "on." Check your water heater – If it powers on, you're good to go; if not, further troubleshooting may be needed. Inspect the Thermostat Settings To guarantee your water heater is operating at its best, it's essential to inspect the thermostat settings regularly. Start by checking the temperature setting; it should typically be around 120°F for peak performance. If it's set too low, you mightn't get enough hot water, while a higher setting can lead to scalding and increased energy bills. Next, make sure the thermostat is functioning properly. You can do this by adjusting the temperature and observing if the water heats up accordingly. If you notice inconsistencies, the thermostat may need replacement. Lastly, don't forget to check for any wiring issues or loose connections that could affect the thermostat's performance. Regular inspections can help prevent common plumbing issues that lead to costly repairs and ensure your water heater operates efficiently. Taking these steps can help you maintain a consistent hot water supply and prolong the lifespan of your water heater. Regular inspections save you time and money in the long run! Examine the Water Heater Tank for Leaks Maintaining your water heater's performance goes beyond just inspecting the thermostat; it's also important to examine the tank for leaks. Leaks can lead to significant damage and higher utility bills, so don't overlook this critical step. Here's how to check for leaks effectively: Inspect the Tank Exterior : Look for any signs of moisture or water pooling around the base of the tank. Check Connections : Examine all inlet and outlet connections for drips or corrosion. Look for Rust or Corrosion : Pay attention to any rust spots on the tank, as they can indicate a potential leak. Listen for Sounds : If you hear hissing or dripping noises, this might signal a hidden leak that needs immediate attention. Additionally, remember that corroded water pipes are a common cause of leaks, so be vigilant in your inspections. Flush the Tank to Remove Sediment Buildup Flushing the tank regularly helps remove sediment buildup that can hinder your water heater's efficiency. When minerals and debris accumulate at the bottom, they can cause overheating and reduce the effectiveness of your heater. To flush the tank, first, turn off the power supply and close the cold water inlet valve. Connect a garden hose to the drain valve at the bottom of the tank and place the other end in a suitable drainage area. Open the drain valve and allow the water to flow out. As the tank empties, you may notice sediment being washed away. Once the water runs clear, close the drain valve, remove the hose, and reopen the cold water inlet valve to refill the tank. Don't forget to turn the power back on. Regular flushing can extend your water heater's lifespan and improve its performance, so make it a part of your maintenance routine. Replace the Anode Rod for Longevity To keep your water heater running smoothly, you can't overlook the anode rod. This essential component helps prevent corrosion inside the tank, extending its lifespan considerably. Make it a habit to check and replace the anode rod every few years to guarantee peak performance. Importance of the Anode Rod An anode rod is an essential component of your water heater, playing a crucial role in preventing corrosion and extending its lifespan. By attracting corrosive elements, the anode rod sacrifices itself to protect the tank. Here's why you should prioritize its maintenance: Corrosion Prevention : It helps prevent rust from forming inside your tank. Extended Lifespan : A well-maintained anode rod can greatly prolong the life of your water heater. Cost Efficiency : Replacing the anode rod is cheaper than replacing the entire unit. Improved Efficiency : A healthy rod enhances the overall efficiency of your water heater, saving you money on energy bills. Regularly checking and replacing your anode rod is a smart investment for long-lasting hot water comfort. Replacement Frequency Guidelines Regular maintenance of your water heater includes checking the anode rod to confirm it's in good condition. This rod plays a vital role in preventing corrosion, and replacing it every three to five years is a smart practice. However, if you notice significant corrosion or a foul smell, it's time to replace it sooner. For homeowners in Wickliffe, OH, keeping an eye on the anode rod helps extend the life of your water heater and can save you from costly repairs down the line. When you replace the anode rod, choose a high-quality magnesium or aluminum option for the best protection. By staying proactive with this simple task, you guarantee your water heater operates efficiently and lasts longer. Call a Professional for Complex Repairs When dealing with complex repairs like a broken water heater, it's essential to recognize when to call in the professionals. Tackling these issues on your own can lead to further damage or safety hazards. Here are some signs it's time to reach out to an expert: Leaking Water : If you notice significant leaks, it could indicate serious internal damage. Unusual Noises : Banging or popping sounds often signal sediment build-up or mechanical failure. Temperature Issues : If your water isn't heating properly or fluctuates wildly, a professional can diagnose the problem. Old Age : If your heater is over ten years old and showing signs of wear, it's best to consult a technician. Calling Formica Plumbing & Sewer Co. guarantees you get reliable, expert service. Their licensed professionals are ready to handle your water heater woes with care and efficiency.
