How To Flush Hot Water Heater

Is your hot water lukewarm, rusty, or just not performing as it should? It might be time for a good old-fashioned hot water heater flush! This process can significantly improve your water heater's efficiency and lifespan. This guide will walk you through the process safely and effectively.

Why Flush Your Hot Water Heater?

Over time, sediment builds up at the bottom of your hot water heater tank. This sediment – a mixture of minerals and rust – reduces efficiency, wastes energy, and can even lead to premature failure. Flushing removes this buildup, restoring your water heater to its optimal performance. Here are some key benefits:

  • Improved Efficiency: Less sediment means less energy wasted heating up unnecessary material. You'll see a noticeable difference in your energy bills.
  • Longer Lifespan: By removing corrosive sediment, you extend the life of your water heater.
  • Better Water Quality: Say goodbye to rusty or discolored water! A clean tank ensures cleaner, better-tasting hot water.
  • Prevent Premature Failure: Sediment buildup can cause damage to internal components, leading to costly repairs or replacement.

Tools and Materials You'll Need:

Before you begin, gather these essential items:

  • Garden hose: A sturdy one is best to handle the water pressure.
  • Bucket: For catching the drained water.
  • Adjustable wrench: For loosening and tightening connections.
  • Safety glasses: Protect your eyes from splashing water.
  • Gloves: To protect your hands from hot water and sediment.
  • Old towels: For cleanup.

Step-by-Step Flushing Process:

Caution: Always turn off the power to your electric water heater or the gas supply to your gas water heater before starting this process. Hot water can cause serious burns.

1. Prepare the Area: Clear the area around your water heater to ensure you have enough space to work comfortably and safely. Lay down old towels to prevent water damage.

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

3. Drain the Water Heater: Attach the garden hose to the drain valve located at the bottom of the water heater. Guide the other end of the hose to a drain or bucket outside to collect the drained water. Slowly open the drain valve. Be prepared for the hot water and sediment that will come out.

4. Flush the Tank: Once the tank is nearly empty, close the drain valve. Turn the cold water supply back on briefly to flush the tank. Let it run for a few minutes, then turn off the water supply again. Repeat this process 2-3 times until the water runs clear.

5. Refill and Inspect: Turn the cold water supply back on and allow the tank to refill completely. Check for any leaks around the drain valve and connections.

6. Turn On the Water Heater: Once the tank is full, turn the power (electric) or gas supply back on.

Maintaining Your Water Heater:

Regular flushing is crucial for maintaining your water heater's performance. Consider flushing your water heater once a year or more frequently if you notice a decrease in hot water quality or efficiency.

When to Call a Professional:

While flushing your water heater is a relatively simple DIY task, there are times when it’s best to call a professional plumber:

  • Significant sediment buildup: If the water remains heavily clouded even after multiple flushes.
  • Leaks: If you notice any leaks during or after the flushing process.
  • Age of your water heater: If your water heater is very old and showing other signs of wear, professional servicing is advisable.

By following these simple steps, you can keep your hot water heater running smoothly and efficiently for years to come. Remember safety first!
