# Water Heater Popping or Rumbling in Charlotte, SC

A tank water heater that pops, rumbles, or crackles while it heats usually has sediment built up on the bottom. Left alone, it can cut efficiency and shorten the life of the tank.

- Flushing a few gallons from the drain valve once a year helps clear sediment.
- Hard water speeds up buildup, so homes with heavy mineral water may need it more often.
- Watch for water around the base of the tank, which can mean a leak is starting.
- Ask a local plumber to flush it or check it if the noise gets louder or hot water runs short.
