How to Flush a Water Heater to Stop Popping Noises · Step 7 of 10
In this video
Once the tank is fully drained and the drain valve is closed, disconnect the garden hose. Using an adjustable wrench, turn the old drain valve counter-clockwise to unscrew it from the water heater tank. Be prepared for a small amount of residual water to spill out as you remove the valve. Use rags or towels to catch this water.
Goal: Remove Faulty Valve
- Have a few rags handy as some additional water may drain out during this step.

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.
