- Higher utility bills

DIY Water Heater Flush in Vancouver, WA: Step-by-Step
You can perform a DIY water heater flush in Vancouver, WA using basic tools and a little patience. Here’s how:
Step 1: Turn Off Power or Gas
- For electric heaters, switch off the breaker in your electrical panel.
- For gas heaters, turn the thermostat to the “pilot” setting.
Step 2: Shut Off the Cold Water Supply
Find the cold water valve at the top of the heater and turn it off. This stops new water from entering the tank during the flush.
Step 3: Connect a Hose to the Drain Valve
Attach a garden hose to the drain valve near the bottom of the tank. Run the other end to a floor drain, sump pump, or outside.
Step 4: Open a Hot Water Tap
Open a hot water faucet somewhere in your home to relieve pressure in the system and allow for easier draining.
Step 5: Drain the Tank
Open the drain valve and let the water flow out. Be cautious, it may be hot. Let it run until the tank is completely empty.
Step 6: Flush with Fresh Water
Once drained, turn the cold water supply back on briefly to stir up and flush out any remaining sediment. Repeat until the water runs clear from the drain hose.
Step 7: Close Everything and Refill
Close the drain valve, remove the hose, and turn the cold water supply back on fully. When the hot water tap runs steadily, turn it off.
Step 8: Restore Power or Gas
Turn the breaker back on or reset the gas thermostat to the desired temperature. Wait about 30–60 minutes for the water to heat back up.
