How to Flush a Water Heater to Stop Popping Noises · Step 5 of 9
A comprehensive guide to flushing a water heater tank to remove sediment buildup. This process involves shutting off the power and water supply, draining the tank, using cold water pressure to flush out accumulated minerals, and then safely refilling and restarting the unit. This maintenance procedure is the primary method for resolving popping or rumbling noises caused by trapped water boiling beneath a layer of sediment.

FAQs
Why is my water heater making popping or rumbling noises, and how does flushing fix it?
Popping or rumbling noises are typically caused by sediment (like calcium, magnesium, or rust) accumulating at the bottom of your water heater tank. Water trapped beneath this layer gets superheated and boils, creating steam bubbles that cause the popping sounds as they escape. Flushing removes this sediment, allowing the heating element to heat water directly and quietly.
What essential safety gear and tools do I need before starting this project?
For safety, ensure you have safety glasses (e.g., HDX Clear Indoor Safety Glasses), heat-resistant gloves (Dyna-Glo Grilling Glove), and general work gloves. Key tools include a heavy-duty garden hose (like GardenJoy PVC Garden Hose) for draining, Channellock Tongue and Groove Pliers for valve adjustments, and a Milwaukee Slotted Flat Head Screwdriver.
How long will this project take, and how difficult is it for a beginner?
For a beginner, this project typically takes 1-2 hours to complete, including the shutdown, draining, flushing, refilling, and restart process. It's considered a beginner-level DIY task, but requires careful attention to each step to ensure all sediment is removed and the system is safely restarted without issues.
What are some common mistakes to avoid when flushing my water heater?
A common mistake is not fully shutting off both the power and the cold water supply to the tank before beginning the drain. Also, ensure your drain hose is securely connected to prevent leaks and water damage. After refilling, always remember to purge all air from the system by opening a hot water faucet to prevent airlocks.
