How To Empty Water Heater

Draining your water heater might seem daunting, but it's a manageable task that can extend the life of your appliance and prevent costly repairs. Whether you're preparing for maintenance, relocating, or simply need to flush sediment, this guide will walk you through the process safely and efficiently.

Why Empty Your Water Heater?

Several reasons necessitate draining your water heater:

  • Sediment Buildup: Over time, sediment accumulates at the bottom of the tank, reducing efficiency and potentially causing damage. Regular draining helps remove this sediment, improving performance and longevity.
  • Maintenance and Repairs: Emptying the tank is often a necessary step before performing maintenance or repairs on your water heater.
  • Relocation: If you're moving, draining the water heater is crucial to prevent leaks and damage during transportation.
  • Preventative Measures: Periodic draining can help prevent more serious problems down the line.

Tools and Materials You'll Need:

Before you begin, gather these essential supplies:

  • Bucket(s): Several large buckets are needed to collect the hot water.
  • Garden Hose: To drain the water efficiently.
  • Adjustable Wrench: For loosening the drain valve.
  • Gloves: Protect your hands from hot water and potential debris.
  • Old Towels: To soak up any spills.
  • Safety Glasses: To protect your eyes from splashing water.

Step-by-Step Guide to Draining Your Water Heater:

1. Turn Off the Power/Gas: This is the most crucial first step. Turn off the power to electric water heaters at the breaker box, and turn off the gas supply to gas water heaters at the valve.

2. Turn Off the Water Supply: Locate the shut-off valves for the cold water supply lines connected to your water heater. Turn these valves clockwise to shut off the water flow.

3. Prepare for Drainage: Position your buckets and hose. Attach the garden hose to the drain valve located at the bottom of the water heater. The other end of the hose should lead to a suitable drain, like a floor drain or outside.

4. Open the Drain Valve: Carefully use your adjustable wrench to open the drain valve. The water will begin to flow out. Be prepared for hot water!

5. Monitor the Drain: Keep a close eye on the water level and add more buckets as needed. The draining process may take some time.

6. Flush the Tank (Optional): Once the water has mostly drained, you can flush the tank by briefly turning the cold water supply back on for a short period to help remove sediment. Turn it off again once sediment starts coming out with the clear water.

7. Close the Drain Valve: Once the draining is complete, close the drain valve tightly using your wrench.

8. Turn the Water Supply Back On: Slowly turn the cold water supply valves counterclockwise to restore water flow to the heater.

9. Turn the Power/Gas Back On: Once the water is flowing normally, you can safely turn the power or gas supply back on to your water heater.

Important Safety Precautions:

  • Hot Water Warning: The water in the tank will be extremely hot. Exercise caution to avoid burns.
  • Pressure Relief Valve: If your water heater has a pressure relief valve, leave it alone during this process.
  • Professional Assistance: If you are uncomfortable performing this task yourself, consult a qualified plumber.

By following these steps, you can confidently drain your water heater, ensuring its optimal performance and extending its lifespan. Remember, safety is paramount – take your time and prioritize your well-being throughout the process.
