Common Types of Water Heater Noises and Their Causes

There are a few different sounds you may hear coming from your water heater, and each of them may have various causes.
Popping or Banging Sounds
Popping and banging sounds are some of the most common when it comes to water heaters. Many homeowners describe the sound as something banging against the wall of their heater, which is relatively accurate, as this sound is often caused by sediment buildup.
Sediment is an accumulation of solid particles in your water. Sediment can include things like sand, dirt and other loose particles; however, when it comes to a water heater, sediment is mainly comprised of magnesium and calcium. If you live in an area with hard water, naturally occurring minerals like magnesium and calcium can separate from your water when heated, leading to hard, calcified pebbles in your tank. These floating particles can bang against the walls of your tank as the water heats up.
Sizzling or Hissing
Sizzling sounds usually occur when hot water from your tank makes contact with the heating element or when water leaks out of your tank and makes contact with surrounding structures or the outside of your tank.
In this situation, it is vital that you inspect your water heater for hissing sounds while the tank is on. You should also inspect the area around your water heater for moisture. If there are no visible leaks, then condensation buildup in your tank may lead to water dripping on the heating element.
How to Fix Odd Water Heater Noises
Regular water heater maintenance is key to preventing unusual noises from your water heater tank. Flushing your tank once or twice a year can help remove excess sediment buildup, which can prevent popping sounds. General water heater maintenance and inspections from an experienced plumber in Boca Raton can help you catch any serious leaks or damage early.
