How To, and Can You fix a Clogged Water Heater
See the older the water heater the less efficient they are for energy costs and for usage. (But this to depends on your budget.)
To get to the point. I would just recommend to replace the water heater, usually.
For the simple reason if it has that much sediment Build Up, it probably is a very old water heater. And like I said it isn't very efficient.
And I would not drain the water heater inside unless you know what your doing.
But if you must drain:
Make sure You Turn the Water OFF. If it's outside open the valve (hose Bibb on Water heater) and drain it. If it's to clogged, with sediment. Take off the Hose Bibb or unscrew it. And stick a screwdriver in.
And it should drain, when the water is turned off above the water heater very little water will come out, so open a faucet inside ( Hot Side). And install a new Hose Bibb, on the Water Heater.
Like I said, If the water heater is inside. You have to be Very careful you don’t want the WATER To go EVERYWHERE, it’s really Best to Call a professional.
