How often should a water heater be flushed?
In our region, due to extreme water hardness, we strongly recommend flushing the tank once every 12 months to prevent permanent scale hardening.

Water Heater Flush
Hard water contains dissolved minerals that precipitate out when heated, settling at the bottom of your water heater. Over time, this sediment forms a thick, rock-like layer that forces your burner to heat through the rock to reach the water. A professional flush clears this debris, restoring efficiency and extending the tank's life.
When this service makes sense
We attach a high-flow hose to the drain valve and perform a pressurized flush, repeatedly agitating the water to break loose stubborn calcified chunks. We monitor the discharge until the water runs completely clear, then test the pressure relief valve to ensure it operates safely.
- Loud popping, knocking, or rumbling sounds when the burner turns on
- Hot water supply runs out much faster than it used to
- The drain valve clogs instantly when you try to drain it yourself
- It has been more than 12 months since the last flush

What to expect
Your tank will operate more quietly and heat water faster. By removing the insulating layer of sediment, the burner won't have to work as hard, which reduces thermal stress on the steel tank and lowers the risk of premature leaks.

Common questions
Can a flush fix a leaking tank?
No. If the steel tank itself is leaking, a flush cannot reverse the structural damage. The unit must be replaced.
Will a flush restore my lost hot water capacity?
Yes, by removing the volume of sediment taking up space at the bottom of the tank, you regain that volume in usable hot water.
