How Do I Know If My Hot Water Tank Is Failing?

ShowerheadMany people don't realize how much they depend on their hot water heaters to make their lives comfortable until something goes wrong. Not having hot water is a huge inconvenience, making it impossible to take a hot shower, sanitize your dishes in the dishwasher, and properly clean your clothes. The last thing anyone wants to deal with is a complete water heater breakdown, so make sure you're aware of these signs of a faulty water heater. The sooner you identify a potential issue, the sooner you can call for repairs and avoid a disaster!

4 Signs You Need Professional Water Heater Repair

  • Shorter showers. If your hot showers are getting shorter and shorter, your hot water tank could be failing. The problems can range from a bad gas burner or electrical heating components to broken dip tubes. If your hot water heater is older than seven years, getting a new one will be easier than trying to find replacement parts.
  • Dirty water. Dirty water coming from your tap or shower could be a sign that your hot water tank has a sediment build up problem. If it is under seven years old, then flushing the tank may solve the problem; otherwise you should just replace the hot water heater. If your neighbors are also getting dirty water at the tap, the problem is a water line break, a damaged well or bad water from your water company.
  • Smelly water. Does the water coming from your tap smell like rotten eggs? This could be a sign that you have bacteria in your hot water heater. The best way to get rid of the bacteria is to raise the hot water heater temperature above 140 °F for several hours then flush the tank and have a plumber install a zinc rod to keep the bacteria away for good. If your water has a metallic smell, your tank may be rusted on the inside.
  • Unusual noises. If your hot water heater is making strange noises, it is a sign that something is wrong. Loud swirling noises are caused by damaged dip tubes. Hissing sounds are caused by problems with water supply or small leaks. A knocking or whistling sound are signs that you have sediment buildup in your hot water which can be fixed by flushing the tank.
