How to Flush Your Water Heater for Better Performance
Over time, sediment builds up inside your water heater tank, reducing efficiency and shortening its lifespan. Flushing your water heater annually — or twice a year in areas with hard water — can make a big difference in performance.
Why Flushing Matters
Sediment buildup:
- Reduces heating efficiency
- Causes strange noises (popping, rumbling)
- Increases wear on heating elements
- Can clog water lines and reduce pressure
Flushing Steps (for traditional tank water heaters):
- Turn Off Power or Gas Supply – Electric heaters: switch off the breaker. Gas heaters: turn the control to “pilot.”
- Turn Off Cold Water Supply – This stops new water from entering the tank.
- Connect a Garden Hose – Attach it to the drain valve at the base of the heater.
- Drain the Tank – Run water into a safe location until clear.
- Flush with Fresh Water – Briefly turn on the cold water to rinse remaining sediment.
- Close the Valve & Refill – Then restore power or gas.
For Tankless Units
Tankless systems also need maintenance to remove scale buildup, especially in coastal areas like Santa Monica. This process requires circulating a descaling solution through the unit — best done by a professional.
Regular flushing keeps your water heater running efficiently and extends its life. At Santa Monica Drain Co., we offer full maintenance services to keep your hot water flowing year-round.
