We’re going to go through the fundamental procedures since descaling a water heater is one of the maintenance jobs that many homeowners can do without much help.
Start by cutting off the power to your water heater.
Find the gas isolation valve, then shut it.
As you work on the appliance, cut off the hot and cold water valves to keep water out of the device.
Open the pressure relief valve on your appliance if it has one to gently release any pressure.
Next, attach the hoses from your flush kit to the hot and cold water service ports on your plumbing system.
The submersible pump should then be placed in your bucket.
Put one end of the hot water hose in the bucket and connect the cold water line to the pump.
Now you may either fill the bucket with four gallons of vinegar or the descaler that came with the flush package.
Open the cold and hot service ports, then start the submersible pump to flush the water heater.
Give the water heater at least one hour to circulate your selected descaling solution.

Descaling completed, shut off the pump.
Next, discard the vinegar.

After that, you’ll shut the valve and let the water to completely drain.
The hot water port should now be shut.
Finally, if there is a hot water in-line filter and a cold water input filter, remove them both.
