Should a person wait till the water heater springs a leak , before replacing
it? I ahve an alarm on the heater to indicate a leak. I can install a heater
I have the temp set low enough that adding cold water to take a shower is at
a minimal. So I am not overheating the water just to have to cool it down.
What is the adverage life expectency of a natural gas heater?
In my experience, typical is around 10-13 years. Whether to replace it
preemptively depends a lot on where it's located. If it's in a
location where water damage from a leak could be significant, then I
would replace it for sure at 13 years.
Also, there is an sacrificial anode in most water heaters that is
easily removable/replaceable. It's there to slowly corrode instead of
the tank. If you check it every few years and replace before it's
gone, you can supposidly extend the life of the tank. I just became
aware of this and just checked mine on a tank that is about 6 years
old. I'd say it's about half gone, so I'm gonna recheck in 2 years.

I looked for my sacrificial anode a little bit, and couldn't find it.
Even if I did find it, I have a shelf about 15 inches above the WH.
Would I be able to get the old one out or the new one in?
I'm waiting for my 28-year-old natural gas heater to spring a leak before it
gets replaced. I don't know if the anode has ever been replaced (I bought
this place 1 year ago) but if it's lasted this long I suspect it has been
replaced once or twice. It's a combo-type anode/hot water outlet thing so I
don't really care to disassemble the heater to find out. It is, after all,
28 years old. (and, if it hasn't been replaced, it has 28 years of rust to
hold it in place - not fun to remove, may very well break something on the
tank in the process)
If it ain't broke ...
I replaced mine when it began making a puddle in 1996. This afternoon,
I'll finish up the connections to the replacement I bought yesterday:
ten years is about average over here.
It has always annoyed me that water heaters don't include the pressure
relief valve ... which is certainly not an optional feature. I bought
one along with my new tank at HD.
Surprise: the new tank included the valve, as well as the dielectric
break nipples (which I also bought). So I get to make yet another
visit to HD.
