Although hot water heaters can differ from model to model, they all operate on similar ideas. Below are some common hot water heater repair issues.
List of our other services.
1. Heating Elements
Most electric hot water heaters use 2 heating elements to heat the water in the tank. One element will be near the bottom of the tank, the other will be near the middle.
These heating elements are controlled by individual thermostats. When the set temperature is reached, the heating elements will cycle off.
The lowest temperature setting available will rarely turn the heating elements on. The maximum temperature setting is usually around 150 degrees.
Most manufacturers suggest setting your temperature no higher than 120 degrees.
2. Temperature Setting
Having an incorrect setting can cause your water to be too cold, too hot, or cause your heating elements to work constantly. This will not only cause your elements to wear faster, but your electric bill will be very high. For these reasons it is recommended to have a professional set your thermostats and make sure they have no damage. Hot water heater repair should be done by licensed professionals.
3. Dip Tube
The dip tube in your water heater makes sure the incoming cold water is distributed evenly throughout the tank. A broken or deteriorated dip tube can cause the cold water to stay near the top, making your water heater unable to heat the water properly.
The interior of you water heater is coated in enamel that helps protect the metal from minerals and salt that are found in water supplied. To help protect your water tank, an anode rod in the tank will actively collect corrosive minerals. If this rod is damaged or not working, the minerals in you water can deteriorate your tank. When replacing this equipment be aware of electrical shock and very hot water. Hot water heater repair can be dangerous if you are not a licensed plumber.
Most water heaters will have two drain valves on them. The valve on the bottom is used to drain out the tank once every couple of years to avoid extra mineral deposits accumulating in the bottom of the tank. The valve at the top is a safety release valve that will open if the pressure or heat inside the tank rises above normal. This valve must have a discharge tube attached, and must extend to about 6 inches from the floor. This is to prevent hot water spraying out of the tank and possibly injuring someone.
If either of these valves are leaking they have failed and need to be replaced as soon as possible.
If the tank has any leaks, the water supply should be turned off immediately.
Hot water heater repair can be dangerous.
The risk of burns or electrocution are often overlooked. Please contact a professional to fix and maintain your hot water heater.
