Six Reasons for a Reduced Hot Water Supply

March 16, 2020

Having access to hot water is a luxury that should not be taken for granted, and you can’t have hot water without a properly functioning water heater. Here are six potential water heater malfunctions in Coweta County, GA that may be responsible for the lack of hot water in your home:

  • Failing pilot light or burner: If you have a gas-powered water heater, then your tank has a burner that supplies the hot combustion gas. This hot gas heats up the water inside the tank. When a burner begins to fail—typically due to grime, low gas pressure, a broken ignitor or an intermittent pilot light—heat has a more difficult time entering the tank.
  • Faulty gas control valve: A malfunctioning gas control valve will cut off the gas supply to the burner. Without gas, the burner cannot heat the water inside the hot water heater tank.
  • Failing electric heating element: Electric water heaters have two heating elements inside the tank to ensure there’s enough energy to raise the water temperature. The burner unit sits below the tank and releases jets of gas to ignite and transfer heat to the water in the tank. Dirt or corrosion will cause the burner to have to struggle to draw oxygen to ignite, and if one burner fails, there will be less hot water in the tank for household use.
  • Damaged dip tube: This component carries cold water from your home’s water main into the heater. The tube runs into the top of the water tank and carries the water to the bottom of the tank, which is where the heat exchanger or heating elements are located. Once the water from the dip tube heats up, it rises to the top of the tank, where it’s then pumped throughout the piping in the house.
  • Leaking tank or connectors: Any sort of leak that developed along the connectors to the tank, within the tank itself or in a pipe will cause a drop in the tank’s water supply. This in turn means less hot water. Leaking is a serious problem that can ruin your water heater, a problem that can lead to water damage to the inside of your home and belongings. If you spot a leak or notice a drop in hot water, look around the tank for water pooling around it. Call a pro for an inspection and repairs before things get worse.
  • Old water heater: Depending on the make, model and installation service, your water heater can last 12 to 15 years. Any time past this may result in a loss in efficiency, and the tank and connections will begin to deteriorate. If you have an old water heater and you notice a reduction in your hot water supply, it’s probably time to get a replacement.

Don’t ignore a noticeable drop in hot water. Doing so will leave you with only cold water for bathing, cleaning clothes and dishes and washing your hands. Call Victor Moody Plumbing Inc. in Coweta County, GA as soon as you notice water heater issues in your home!
