A water heater is one of the most essential appliances in any home, but it often gets overlooked until something goes wrong. One simple yet highly effective way to maintain your water heater and extend its lifespan is by flushing it regularly. In this guide, we’ll explain what water heater flushing is, why it’s important, and how to get it done.
What Is Water Heater Flushing?
Water heater flushing is the process of draining and cleaning your water heater’s tank to remove sediment, minerals, and debris that accumulate over time. These deposits are common in areas with hard water, like much of Idaho, and can lead to performance issues if left untreated.
Why Is Water Heater Flushing Important?
Improves Efficiency
Over time, sediment buildup acts as an insulating layer between the heating element and the water, making your water heater work harder to heat the water. Flushing the tank restores efficiency, saving you money on energy bills.
Extends the Lifespan of Your Water Heater
Sediment can corrode the inside of the tank, leading to leaks and potentially costly repairs. Regular flushing helps protect your water heater and prolong its lifespan.
Prevents Strange Noises
If you hear rumbling or banging noises from your water heater, sediment is likely the culprit. These sounds occur when heated water bubbles through the sediment. Flushing the tank eliminates this issue.
Ensures Reliable Hot Water
Sediment buildup reduces the tank’s capacity, meaning less hot water for showers, laundry, and dishes. Regular maintenance ensures you always have enough hot water when you need it.
How Often Should You Flush Your Water Heater?
Experts recommend flushing your water heater at least once a year. However, if you live in a hard water area like the Treasure Valley, more frequent flushing (every 6–8 months) may be necessary.
How to Flush a Water Heater
While it’s always best to hire a professional plumber for safety and effectiveness, here’s a general overview of the process:
- Step 1: Turn Off the Power or Gas
For electric water heaters, switch off the power at the circuit breaker. For gas heaters, set the thermostat to “pilot.”
- Step 2: Shut Off the Water Supply
Turn off the cold water supply valve at the top of the tank.
- Step 3: Connect a Hose to the Drain Valve
Attach a garden hose to the drain valve at the bottom of the tank. Place the other end of the hose in a safe area where the hot water and sediment can drain.
- Step 4: Drain the Tank
Open the drain valve and let the water flow out completely. Open the hot water tap in a nearby sink to allow air into the tank for faster draining.
- Step 5: Flush the Tank
Turn the cold water supply back on briefly to flush out any remaining sediment. Let the water drain until it runs clear.
- Step 6: Close the Valves and Refill
Close the drain valve, remove the hose, and turn the cold water supply back on. Once the tank is full, reopen the hot water tap to let out any air and ensure water is flowing smoothly.
- Step 7: Restore Power or Gas
For electric models, turn the power back on at the breaker. For gas models, switch the thermostat from “pilot” to your desired temperature.
Why Hire a Professional for Water Heater Flushing?
While flushing your water heater may seem straightforward, it can be risky if not done correctly.
Hiring a professional ensures:
- Safety: Handling hot water and pressurized systems requires care and expertise.
- Thorough Cleaning: A plumber has the tools and knowledge to remove all sediment effectively.
- Damage Prevention: Professionals can identify and address any underlying issues during the process.
