Hey all. I have a question: what is the average lifespan of a water
heater? We have one (40-gallon, gas) which is original to the house, so
about 14-15 years old. We noticed lots of corrosion on the top water
lines and the occasional small amount of water on the floor, and planned
to have the thing inspected. Unfortunately, since Sunday night there's
been a larger amount of water leaking from the very bottom of the heater,
so instead of an inspection it'll probably be a replacement.
I guess that leads me to other questions: how do you drain a water
heater? I've heard you should drain it once a year for maintenance, but
have no idea what that means or if it's effective. Also, how can I keep
that corrosion from building up on the new one?
And yes, this is our first home :P

Due to slightly acidic water, my water heaters only last about 6 years.
Usually leaking at the bottom means you should replace the unit. Your
first leak sounds like a deteriorated over pressure valve.

In my locale, the tap water is basically undrinkable "canal water".
I've had my current house for two years, and I believe the WH was replaced
not long before the sale.

Are there any maintenance recomendations for areas where the water is
extremely hard?
