Gas Water Heater- repair or replace
I have a 14 year old 40-gallon A.O. Smith gas water heater. It has never received any maintenance (still has original Anode, thermostat, never been flushed). It seems to be working fine though.
However I'm concerned about a water heater that old that wasn't taken care of. I'm debating whether to preemptively replace it or just leave well enough alone.
So some opinions if you please...
A) replace the anode, thermostat and flush it
B) leave everything alone until it fails and then buy new
C) buy new now and start maintaining it properly
