How to Dissolve Sediment in Water Heater

Effective methods to dissolve sediment in water heaters

• Vinegar flush to remove mineral buildup:

  • Drain the tank and add a gallon of cider vinegar to dissolve sediment
  • Let it sit for at least 6 hours to effectively clean sediment out of hot water tank
  • Re-open the valve and flush the tank again to remove remaining mineral buildup and vinegar
  • This method is cost-effective and environmentally friendly for dissolving sediment in water heaters

• Manual cleaning to remove sediment:

  • Drain the tank completely to prepare for cleaning sediment out of hot water tank
  • Remove the bottom element of the water heater
  • Use a wet vacuum with a small hose to clean scale and mineral buildup off the bottom
  • Replace the element and flush the tank before reconnecting to remove dissolved sediment

• Regular maintenance to prevent sediment buildup:

  • Flush the tank twice per year if you have hard water, or once annually otherwise
  • This helps prevent excessive sediment buildup in water heaters over time

What not to use when dissolving sediment in water heaters

• Avoid CLR or Lime Away:
  • These products are not recommended for use in removing mineral buildup from water heaters
  • They can leave a lingering scented soapy solution in the heater

Additional considerations for cleaning sediment out of hot water tanks

• Replace safety devices:

  • Consider replacing the sacrificial anode and T&P valve
  • Corrosion may have damaged these important safety devices

• Water softener installation:

  • If you have hard water, consider installing a water softener
  • This can help prevent future mineral buildup in water heaters

Benefits of sediment removal from water heaters

• Improved performance:

  • Removing sediment can increase energy efficiency and extend the lifespan of your water heater

• Prevent damage:

  • Sediment buildup can corrode the tank's lining, potentially leading to a burst tank and water damage
