Metal and water simply don’t mix. Sediment buildup or corrosion is one of your waters heaters worst enemies and the byproduct of minerals in the water. Calcium and rust are two of the most common and can cause your water heater to work less effectively and efficiently. As sediment builds up on the bottom of your tank, it can create a barrier between the water and the heats source. Leaving lukewarm water. To prevent this from happening it is important to stay on top of your water heater maintenance. Tank water heaters should be drained and flushed annually to prevent sediment buildup.

  2. Loud banging inside the tank when the water heater is engaged.
  3. Visible signs of sediment, like rust outside of the tank.

A broken dip tube can leave cold water at the top of the tank, where the hot water outlet is located. A dip tube can be replaced, however, if your water heater is 10 years old or older, it may simply be time to replace your water heater.
