Like most people, your water heater is probably stored out of sight and is rarely thought about until there’s a problem. However, most people don’t know that, like many mechanical systems, water heaters require regular maintenance to serve them for the longest period possible.

Below are the most common water heater issues you’re likely to encounter and ways of solving them.

1. Very Little Hot Water

Not having enough hot water is a common problem caused by various factors, including:

  • If your water heater doesn’t provide enough hot water, the problem may be that your tank isn’t big enough to meet your requirements. You can easily solve this by replacing your current water heater with a larger one that meets your needs sufficiently.


  • Having too little hot water can also be fixed by adjusting the temperature on the tank’s thermostat. However, when doing this, you must be careful not to set the temperature too high, as this can lead to an accident.


  • If you have a tankless water heater, the problem could be that your water heater isn’t powerful enough. You might be adding too many fixtures to the unit’s power. It’s advisable to check the number of fixtures your unit can run and adjust them accordingly. In some cases, you should consider replacing your water heater with a more powerful one.

However, before replacing your water heater tank or purchasing a new one, it’s best to contact a local water heater repair professional to diagnose the system and determine the underlying issues.

2. No Hot Water

Your water heater not producing any hot water mainly depends on the type of water heater you use. If your water heater is gas-powered and even after turning on the hot water faucet, the water is still cold, chances are a pilot light has blown out. It may also be that your thermocouple is faulty and needs replacement. If you have an electrical water heater, the problem could be that your water heater has a defective heating element that needs replacement.

Replacing the thermocouple or heating element is a tricky job to do on your own. It would be best to contact a repair professional.

3. Noisy Water Tank

Several things could cause noises from your water tank. Scale buildup on the heating elements and inside the water tank is the most common cause of banging and rumbling sounds. To get rid of the scales, you should drain the tank and descale it. You can easily prevent scale buildup by completely flushing the tank every few months.

If, after doing this, you can still hear loud noises from the water tank, consider having a water heater repair professional come and take a look at it.

4. Leaks From the Water Tank

Leaks result from loose connections, and all you need is to tighten them to solve the issue. But if the leak is coming from your tank, it means your tank is worn out and needs replacement. Even the smallest of leaks could cause catastrophic problems if ignored.

Therefore, at first sight of a leak, always contact the best water heater repair professional in Carrollton, TX.

5. Smelly Water

If you’re having trouble with smelly water, most probably, it’s because your water is infected with bacteria. You can solve this problem yourself by flushing the tank and filling it with a solution of hydrogen peroxide and water. Allow the solution to sit in the tank for about two to three hours, then flush the tank with clean water.

If your water still has an unpleasant smell, contact your local repair professional for further inspection.

6. Dirty, Rusty Colored Water

If water from your tank has a dirty, rust color, the problem could be that your tank has some corrosion inside. The solution to this is to replace the tank. However, a failing anode rod could also be the cause of the problem.

So, before rushing to buy another tank, first try flushing the tank and replacing the anode rod to see if the problem will go away. If the problem persists, contact your water heater repair professional.

7. Water Taking Too Long to Reheat

A faulty heating element, a defective thermostat or buildup of sediments could be the main reasons why your water takes too long to reheat. Always do a routine check of these elements and if you note any damage, contact your water heater repair professional and schedule for a replacement as soon as possible.

8. Water Temperature Too Hot or Cold

This is almost certainly caused by the temperature settings on the thermostat being either too low or high. You can solve this by adjusting the temperature settings on the thermostat. If this doesn’t do the job, try checking the temperature-pressure valve.

If the valve is faulty, the heater won’t turn off upon reaching the correct temperature, meaning your water might be too hot. This is dangerous and needs to be corrected immediately. Contact your water heater repair professional and have them replace the valve.

9. Low Water Pressure

Having narrow pipes is what often causes water to have low pressure. This problem is common to people who live in old homes that had their pipes fitted in a smaller size compared to modern houses.

So in some cases, the problem may not be the water heater but the size of your pipes. You should contact an experienced water heater repair professional to determine whether your home’s pipes need a replacement or the best way forward.
