I have a dewalt cordless impact wrench. It can handle up to 800 ft lb. I will give it a try this weekend. I bought a generic anode rod and hopefully it can fit. Otherwise it’s almost $100 shipped from AO smith.go ahead and attempt to change one... its not very easy to do...
once in a while they will comeout easy but most times you need two people to do the job
one guy has to hold the heater to keep it from turning, spinning on you and the other guy needs
a HUGE socket and pry bar to get the rod to come out,,,
harbor freight has a huge pry bar type socket wrench if you are hell bent on doing this
