How to Flush a Water Heater to Stop Popping Noises · Step 6 of 10
In this video
Using an air pressure device, introduce short bursts of air into the drain valve. This action helps to dislodge sediment and facilitate its removal from the water heater tank. Continue this process until the water runs clear.
Goal: Dislodge sediment
- Do not use excessive air pressure, as it could damage the water heater tank.
- Monitor the water exiting for clarity to determine when the flushing is complete.

FAQs
Why is my water heater making popping noises?
Popping noises typically indicate a buildup of sediment, like mineral deposits and rust, at the bottom of your water heater tank. This sediment traps water underneath, which then boils and creates steam bubbles that burst, causing the popping sound. Flushing your water heater removes this buildup, silencing the noise and improving efficiency.
How often should I flush my water heater to prevent sediment buildup?
It's generally recommended to flush your water heater once a year. However, if you live in an area with particularly hard water, you may benefit from flushing it every six months to prevent excessive mineral accumulation. Regular flushing extends your water heater's lifespan and maintains its efficiency.
What are the essential tools and materials I'll need for this project?
You'll primarily need a garden hose (like a GardenJoy PVC Garden Hose 5/8 in. x 75 ft.) long enough to reach a drain. A Milwaukee 4 in. x 1/4 in. Slotted Flat Head Screwdriver might be necessary to open some drain valves, and a NITECORE 4000 Lumens Tactical Flashlight is very helpful for visibility. Don't forget safety gloves (FIRM GRIP Heavy Duty Large Glove or similar) to protect your hands.
What are the most important safety precautions to take before I start flushing?
Always turn off the power or gas supply to your water heater first to prevent accidental operation and potential damage. Wear sturdy safety gloves (like Work Gloves or FIRM GRIP Heavy Duty Large Glove) to protect your hands, especially when handling the drain valve which can get hot, and be mindful of the hot water draining from the tank to avoid scalding.
