We have an approximately 4 year old gas-fired 50 gallon hot water
heater.

Based on recommendations I saw on one of the TV howto shows, I tried
to unscrew and examine the sacrificial anode for corrosion.

However, I could not get the large nut on top of the water heater to
budge. I tried liberally applying liquid wrench and using as much
force as I dared so as not to damage the gas connection.

Any suggestions on how to loosen the nut?
Also, are such inspections really worthwhile in terms of trying to
extend the life of the water heater or am I best off leaving it all
alone?

Thanks

You do not say what the warranty period is for this heater. If 10y - it may
be to early to change the anode.

"As much force" is relative. I'm not sure what the neede torque is, but
it's a lot. I needed an extension on the wrench. With an extension, you
can apply continuous force and it will let go.

Just gentle force via an extension.

Of course, if you don't do it right, you can mess up the heater :-) IMO
it's worth it, if you do it at the right time. Too early and you've wasted
your effort, too late and it's too late.

Instead of a wrench, use a socket and breaker bar.

As trader4 suggested: USE AN IMPACT WRENCH.

I've changed the anode rod twice on my current water heater. The first
time, with the factory-installed (A O Smith) anode rod, required about
one second with a cheap electric (corded) impact wrench (1 1/16" socket)
after using a generous dose of Liquid Wrench. I didn't need the impact
wrench for the second time since I had installed the anode rod
previously, tightly but not as tight as the factory.

I use a portable air tank and an impact driver. ZZZZZZZZZZZIP!
