Hot water tanks are notorious for developing problems. It can be difficult to understand what’s gone wrong when your hot water system begins acting erratically and shutting off at the worst possible moments. If you’re experiencing hot water problems, the best thing you can do is get to the root cause quickly and fix them. The hot water supply can be a source of frustration and stress during the cold winter months if your system isn’t working properly. Luckily there are some things you can do to help pinpoint the problem. Let’s take a look at some common hot water tank issues and the best ways to fix them.

Look for leaks

The most common cause of hot water tank problems is a leak. A leaking hot water tank can cause the entire system to go off-balance, which can make it difficult to figure out where the problem lies.Hot water systems are pressurized, which means they’re filled with water that’s been heated by the hot water tank. If the hot water tank ever leaks, the water inside will become much cooler than the rest of the system. A leaking hot water tank can make it difficult to tell if your system is losing pressure or if the water inside is too cold. This can lead to other complications down the line, like appliances not getting enough water when they need it. To detect a leak, you can try adding a couple drops of food coloring to the tank from a spray bottle. If you see any change in the water’s color, the tank is leaking.

Check the thermostat and pressure relief valve

Your hot water system has a couple of safety features that can alert you to problems. The first one is a temperature-sensitive switch called a thermostat. The thermostat is designed to shut off the water flow if it gets too hot. The other safety feature is a pressure relief valve. If the water inside gets too hot, the pressure relief valve will open and allow extra steam out of the system.The thermostat and pressure relief valve are usually installed in different locations. The thermostat is usually found on the hot water tank. The pressure relief valve is usually installed inside the house somewhere, often on the cold water side of the house. If either of these safety features are faulty, they won’t work properly and may cause the system to overheat.

Check the temperature sensor

The temperature sensor is a small device that measures the temperature of the water inside the hot water tank. The sensor is usually attached to the bottom of the tank and is responsible for letting the main control panel know if the water inside is too hot or too cold. If the sensor is faulty, the water inside the tank can be too hot or too cold. This can be a big cause of hot water tank problems. To check the sensor, you can remove it from the tank and check it for damage. If it doesn’t look faulty, you can try to replace it with a new one.

Check the main control panel

The main control panel is located inside the house and is responsible for sending the right amount of water to each appliance. If the main control panel is faulty, it won’t be able to send the right amount of water to each appliance, which can cause problems. It may also cause the system to overheat. If you’ve checked the thermostat, the pressure relief valve, and the sensor and they all seem to be working correctly, the main control panel is probably the next place to check. To check the main control panel, you’ll need to shut off the water to the hot water tank. Once you’ve shut off the water, you can unplug the wires and inspect the panel for damage or signs of wear and tear.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.
  • Your older water heater is getting up there in age
  • It's making strange noises
  • You're getting rusty water out of the tap
  • Your hot water doesn't last as long as it used to
  • There are water puddles around the unit
120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon hot water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.

Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
