I have a water heater installed 4 years ago that I want to change the anode rod on. This water heater has the anode rod combined with the outlet nipple. I went to change it but it is hard piped to the water supply, preventing me from easily removing the anode rod. Picture below if it does any good.
What is my best route forward? I would like to plan on changing the anode rod every few years so this isn't a one time thing. I guess I could get a CPVC to brass MIP adapter:
and then a flex line. I hear that flex lines are prone to random leaks and sometimes not allowed to code.
Are there any other routes other than cutting the CPVC every few years and redoing the connection?
