Question Water heater flushing: To Flush or Not To Flush

...That is the question

I bought my house last year, and it has a relatively new gas water heater (2008?)

No idea if its ever been flushed...

Is there consensus on whether to leave it alone or go ahead and flush it?

Not a plumber but I flush my electric heater(s) at least once a year. If I don't my 60 gallon hot tub gets sand like stuff in it.

Get a screw on garden hose cap. Have it ready when you drain the water heeater and be prepared to screw it on the water heater drain spout if you can't shut it off completely.

The cap can be purchased separately or you can borrow one from a daisy chainable lawn sprinkler.

Gas WH's are not as big a problem as electric, where buildup on the elements can cause burnout and poor performance. Are you on city water? Any idea of the hardness of your supply?

city water. But I just had a water softener put in as the water was way too hard for us when we moved in last fall
