Water Heaters
Your water heater is one of the hardest-working appliances in your home—supplying hot water for showers, dishes, and laundry every single day. Yet most homeowners in San Antonio TX, Austin TX, Lakeway, and surrounding areas forget one simple annual step that keeps it running efficiently: a professional water heater flush
The Hidden Problem Inside Your Tank
Hard water is very common across Central Texas. Over time, sediment and mineral buildup settle at the bottom of the tank, creating an insulating layer between the heating element and the water. This forces the unit to work harder, driving up energy bills, reducing efficiency, and shortening the water heater’s lifespan.
How to Flush Your Water Heater (Step-by-Step Overview)
If you’re comfortable with basic maintenance:
- Turn off power (breaker for electric, gas valve for gas).
- Shut off the cold-water supply.
- Attach a garden hose to the drain valve and run it to a safe location.
- Open a hot-water faucet to relieve pressure, then drain the tank.
- Briefly turn the cold water back on to flush remaining sediment until the water runs clear.
- Refill, bleed air, and restore power.
(Homeowner Note: If you’ve never flushed your water heater before or if it’s been a very long time since you’ve flushed your water heater, your drain valve could leak or break as you go through the above steps. If this happens, give us a call and we’ll be there immediately to stop the leak)
