How Is A Water Heater Tank Flushed
Flushing a hot water heater tank is not terribly difficult, but it requires a confident hand to do it safely and correctly. Your Sacramento plumbers turn off power and fuel to the water heater. Running water from a faucet helps to eliminate some of the water in the tank, as well as decreasing its temperature. The plumbers use the drain valve located at the bottom of the tank to release the water currently in the tank. Plumbers may also fill the tank and drain it a second or even a third time, to help clear the sediment from the tank. The last steps include refilling the tank and resuming access to power and fuel. Flushing your hot water heater tank is a fairly simple maintenance task that guarantees a good benefit for you and your home. When you flush the tank at least once a year, you keep more hot water for your household, and less sediment to ruin the tank. To schedule water heater repair or maintenance, contact Ace Plumbing.

Sediment buildups appear in the form of lime scales, usually at the bottom of tanks. In gas water heaters, scaling results in uneven heating and leaks. On the other hand, it can cause lower heating elements to burn out in electric water heaters. In both types, it can lead to clogs in the drain valves.
These things are reasons enough to consider calling in professional plumbers to flush your water heater tank periodically.

How To Flush A Hot Water Heater & How Often You Should Do It
Your water heater is one of the most important plumbing fixtures in your home. Responsible for heating your home’s water supply, homeowners must take care of these systems to prevent water heater failure. One of the best ways to provide preventative maintenance for your water heater is by performing a system flush periodically. While this is something that’s performed by your trusted plumbing professional during annual water heater maintenance, it’s recommended that homeowners flush their systems periodically on their own to keep their units in the best condition possible.
Thats Only Partly Correct
For one, the possibility of your water heater exploding is exceptionally small, I mean small, very small, so dont worry about that.
A situation like that would only come from a complete lack of cleaning or maintaining, and the perfect storm of failed safety devices.
So dont worry about it.
What should you worry about?
How about your wallet?
The first question that comes to mind for most people is, How much does it cost to have your hot water heater flushed?
Well, if you do it, just your time and a little sweat.
If you never clean it, then the tank crud will eventually eat through the tank and begin to leak.
Now you know water heaters only go out between one and four a.m. in the morning. Lol
When they do, they can do considerable water damage depending on where they are located in the home.
This is not to say they always just burst everywhere. Of course, you could get a pretty good leak, but that leak might have started as something small and grown.
Then there’s the fact that most water heaters are never seen throughout the day.
Most water heater leaks, in my experience, were found by the owner’s socks. Walking down the hall and then “squish” wet socks where the leak has finally made it into the main living areas.
Point is, it’s cheaper to clean it than let it lay.
But what else can you do?
