How to Flush a Water Heater to Stop Popping Noises · Step 1 of 8
In this video
Attach a garden hose to the drain valve at the bottom of the water heater tank. Ensure the hose has a rubber gasket inside its fitting to create a good seal. Run the other end of the hose to your prepared filter bucket, which should be placed in a suitable drainage area like a driveway. It's recommended to leave the cold water supply valve to the heater open; this pressure helps push the sediment out more effectively. Using a flathead screwdriver, turn the screw on the drain valve a quarter turn until the slot is parallel with the valve, opening it fully. Let the water drain for 10-15 minutes, or until the water running out of the hose is clear.
Goal: Flush sediment from the water heater tank.
- Leave the cold water inlet valve open. The pressure from the incoming water will help to stir up and push out the sediment from the bottom of the tank.

FAQs
Why is my water heater making popping, rumbling, or crackling noises?
These noises are typically caused by sediment accumulation at the bottom of your water heater tank. As water heats up, it gets trapped under the sediment and boils, creating steam bubbles that burst and cause the audible popping or rumbling. Flushing the tank removes this sediment.
What are the essential tools and safety gear I'll need for this DIY project?
You'll primarily need a garden hose (like the GardenJoy Expandable Garden Hose 3/4 in. x 50 ft.) to drain the tank, a large bucket (e.g., Unger 6 Gal. Heavy-Duty Plastic Bucket) to check sediment, and safety gloves (such as FIRM GRIP Heavy Duty Large Glove or Safe Handler Brown Prime Welding Gloves). Ensure your hose is long enough to reach a suitable drain.
How difficult is it to flush a water heater, and how long does it typically take?
Flushing a water heater is considered a beginner-level DIY project. While it involves several steps, they are straightforward. The entire process, including preparation, draining, flushing, and refilling, typically takes about 2 hours to complete.
What are the most critical safety precautions I must take before starting to flush my water heater?
Before you begin, always shut off the power (for electric water heaters) or turn off the gas supply (for gas water heaters), and close the cold water inlet valve. This prevents accidental electrical shock, gas leaks, and ensures no new water enters the tank while you're working. Always wear safety gloves to protect your hands.
