In every household, a water heater plays a crucial role in providing hot water for various needs such as showers, dishwashing, and laundry. However, when our water heater starts to malfunction, it can lead to inconveniences and disrupt our daily routines. Understanding the common problems that may arise with water heaters can help you diagnose the issue and determine the appropriate course of action. In this article, we will explore some of the most frequent issues encountered with water heaters and discuss possible solutions.

Lack of Hot Water

If you find yourself getting only cold water from your water heater, it indicates a problem that needs to be addressed. Several factors can lead to a lack of hot water:

  • The pilot light might be extinguished: Check if the pilot light is on. If it’s not, relight it following the manufacturer’s instructions.
  • A faulty thermocouple: The thermocouple is responsible for sensing if the pilot light is ignited. If it’s defective, it may shut off the gas supply. Consider replacing it.
  • A broken heating element or a malfunctioning thermostat: Electric water heaters use heating elements to warm the water. If they are damaged, they need to be replaced. Faulty thermostats can also prevent water from heating properly.

Strange Noises Coming from the Water Heater

If you hear unusual sounds coming from your water heater, it’s an indication that something is amiss:

  • Sediment buildup: Over time, minerals and sediments can accumulate inside the tank, causing rumbling or popping noises. Flushing the tank periodically can help prevent this issue.
  • A loose heating element: If you have an electric water heater, a loose heating element could create a humming or vibrating sound. Tightening or replacing the element may solve the problem.
  • A faulty expansion valve: The expansion valve is responsible for controlling the pressure inside the tank. A malfunctioning valve can result in a high-pitched whistling or hissing noise. Replacing the valve may be necessary.

Water Leakage

Water leakage is a common issue in water heaters that requires prompt attention. The causes of leakage can include:

  • A faulty temperature and pressure relief valve: If this valve malfunctions, excess pressure can build up inside the tank, leading to leakage. Replacing the valve can resolve the problem.
  • A leaking drain valve: The drain valve at the bottom of the tank is used for emptying or flushing. If it becomes loose or has a faulty seal, it can cause water to leak. Tightening or replacing the valve may be necessary.
  • A crack or corrosion in the tank: In certain cases, the water heater tank itself may develop a crack or corrosion, resulting in leakage. Unfortunately, in such instances, replacing the entire water heater might be the only solution.

Discolored or Foul-Smelling Water

If you notice that the water coming from your water heater is discolored or has an unpleasant odor, you should address the issue immediately:

  • Sediment buildup: A high concentration of minerals and sediment in the water can cause discoloration. Flushing the tank can help resolve this problem.
  • Anode rod corrosion: The sacrificial anode rod in the water heater is designed to attract corrosive elements that would otherwise damage the tank. If the rod is fully depleted, the tank can begin to corrode, leading to foul-smelling water. Replacing the anode rod can fix this issue.
  • Bacterial growth: Sometimes, certain bacteria can thrive in the warm environment of a water heater, resulting in a musty or rotten egg smell. Flushing the tank with a hydrogen peroxide solution can help eliminate the bacteria.

Inadequate Water Pressure

If your water heater isn’t providing sufficient water pressure, consider the following possibilities:

  • A restricting valve: Some water heaters have a valve that controls the flow of hot water. If it isn’t fully opened, it can affect the water pressure. Make sure the valve is completely open.
  • Sediment buildup: Accumulated sediment can clog the water lines, affecting the water pressure. Flushing the tank may help remove the sediment and improve the pressure.
  • A malfunctioning pressure regulator: If your home has a pressure regulator, it could be faulty, leading to low water pressure. Contact a plumber near you to inspect and replace the regulator if necessary.

Conclusion

Water heater problems can cause significant inconvenience, but many issues can be resolved with proper troubleshooting and maintenance. Regularly inspecting your water heater, performing maintenance tasks, such as flushing the tank, and promptly addressing any problems can help ensure the efficient and reliable operation of your water heater. However, if you are uncertain about the cause of the issue or feel uncomfortable performing repairs, it is always advisable to seek professional assistance from a local plumber.

Reasons Your Hot Water Heater is Not Working and How to Fix

Water heaters are one of the most used appliances in the home. They are the reason you can turn the tap and expect an instant supply of warm water. Water heaters make everyday household activities like taking a shower, washing the dishes, or doing the laundry so much easier.

This is why water heater malfunctions can be so utterly disruptive to your lifestyle. Until it breaks down, most of the time your water heater does its work unnoticed in an out-of-the-way corner of the home. The only water heater that gets attention is one that is not working.

But why do water heater malfunctions happen? How can you detect small issues with the water heater before they become big problems? What are the most common water heater malfunctions and how can you avoid or fix them? Find the answers to these questions in this post.

5 common water heater problems and what to do about them

Insufficient or extremely hot water

Sometimes a water heater will not produce enough hot water or the water is too hot. This is a fairly common problem. To fix it, go to the water heater tank and adjust the thermostat. You may have turned the thermostat down during the summer (to save energy) but forgot to turn it up in winter. Thermostat settings may also change if the water heater is bumped accidentally. If the water temperature doesn’t change after you do this, you may need to replace the thermostat.

A water heater will also have water temperature issues if the tank is leaking, the temperature relief valve has stopped working, the gas control or burner assembly is damaged, or there are mineral deposits in the tank. Temperature-pressure relief valves are easily replaced. You can flush the tank to get rid of deposits. But if the tank is leaking, it is probably time to get a new water heater.

Discolored water

Water discoloration is often caused by a high iron and copper content in the water. If the water in your area has a high mineral content, it will cause problems in the components of the plumbing system and the water heater. You may have issues with lime deposits in pipes, showerheads, and taps. This will show up as scaling inside the water heater, washing machine, and dishwasher. If scale builds up long enough inside a water heater, the appliance will start producing discolored water.

Water discoloration is mostly caused by rust (which is accelerated by scale deposits) or anode rod issues. Depending on how soon you detect the problem, it can easily be fixed, that is if the issue is from the anode rod. If the water from the municipality has high mineral content, you can solve it by installing a whole house water filter or water softener.

Smelly water

Water coming from the water heater may have a bad odor, smell of rotten eggs, sewage, or garlic. If this issue is not noticed with all the faucets in the entire home, it may not be from the water heater. Sometimes water will become smelly if it has not been used for a long time. Running the taps in your home for a while will solve the problem.

If this doesn’t resolve the situation, the water heater could be the cause. Rotten egg and sewage smells are caused by heavy bacteria growth inside the tank. This can be fixed by flushing the tank. A garlic-like smell means you need to relight the pilot light. Gas line damage will also cause a strong smell. If the problem persists, get an expert to inspect the appliance.

Strange noises from the water heater

A noisy water heater may be suffering from excessive mineral buildup and sedimentation. Mineral buildup comes from the water and, as already explained, is worse in areas with hard water. Sedimentation may also happen as a result of issues with the heating element. If you hear the sound of boiling water from the water heater, the system is dangerously overheating due to extreme pressures inside the tank. You need a professional plumber to fix these kinds of problems.

Leaking water heater

Leaks can happen in different parts of the water heater.  Leaks caused by a loose in-line valve are easily fixed. This is the valve that controls the flow of water in and out of the tank. To fix the problem, simply tighten the nut that holds the valve in place. If the leak gets worse, you may need another in-line valve. Pressure relief valves can also leak, but they are also easy to replace.

In addition to the above, the water heater may leak because of age, bad plumbing connections, poor maintenance, corrosion, and too much pressure inside the tank. If you find that water pools near the water heater or there is dripping water from the unit, you have a leak. Most of the time, leaks from the water heater tank means your water heater needs to be replaced.
