Drain the Water Lines — Open Faucet and Drain Valve

How to Flush a Water Heater to Stop Popping Noises · Step 5 of 8
In this video
After the main valve is shut off, go inside the house and open a faucet to drain the remaining water from the pipes. The video shows a bathtub faucet being turned on. Water will flow out initially and then slow to a trickle as the pipes empty. It's best to open both hot and cold faucets at the lowest point in the house to ensure the system is fully drained, preventing any water from flooding the work area.
Goal: Empty water from the household pipes
- Opening a faucet on an upper floor can help break the vacuum and allow the lines to drain faster.

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.
