Why Your Water Heater Builds Up Sediment Over Time
Sediment buildup inside a water heater is normal, especially in areas like Orlando and Central Florida, where water contains natural minerals. Over time, these minerals settle at the bottom of the tank and can cause performance and efficiency issues.
1. Minerals Naturally Found in Water
Most tap water contains dissolved minerals such as:
Calcium
Magnesium
Sand and small debris
When water is heated, these minerals separate from the water and settle at the bottom of the tank, forming sediment.

2. Hard Water Accelerates Sediment Buildup
Central Florida is known for hard water, which contains higher levels of calcium and magnesium. The harder the water, the faster sediment accumulates.
This is why water heaters in Florida often experience sediment problems sooner than expected.
3. Heating Process Causes Minerals to Settle
Every time your water heater heats water:
Cold water enters the tank
Minerals sink to the bottom
Heat hardens the sediment into a thick layer
Over time, this layer becomes difficult to remove without professional flushing.
4. Lack of Regular Maintenance
Many homeowners don’t realize that water heaters require annual maintenance.
Without routine flushing:
Sediment continues to build up
The tank works harder
Efficiency drops
Component wear increases
Regular maintenance helps slow sediment accumulation.
5. Aging Water Heater Tanks
As a water heater gets older:
The anode rod deteriorates
Internal corrosion increases
Sediment sticks more easily to the tank
Older units accumulate sediment much faster than newer systems.
Problems Caused by Sediment Buildup
Sediment buildup can lead to:
Reduced hot water supply
Higher energy bills
Rumbling or popping noises
Overheating of heating elements
Shortened water heater lifespan
Tank failure or leaks
How to Prevent Sediment Buildup
✔ Flush the water heater at least once a year
✔ Install a water softener if you have hard water
✔ Replace the anode rod when needed
✔ Schedule professional maintenance
When Sediment Means Replacement Is Needed
If sediment has hardened for years, flushing may not be enough. In those cases, water heater replacement is often the safest and most cost-effective solution.
