Hi all. First time poster, long time follower of this site. I am a new owner of a Rheem Hybrid H2O (ProTerra 65.) I have been researching how to replace the anode on these with an electric one and can see that it is a bit of a chore that often results in cutting a gasket and voiding the warranty. In looking at the instructions for the Corro-Protec, https://m.media-amazon.com/images/I/81Zcs4PTAJS.pdf, I see they have a secondary set of instructions for installing this rod in the relief valve (steps 4a-4e) - moving the relief valve to a tee on the hot water connection and leaving the old anode in place. I am not able to find any thoughts on doing this. Wondering what you all think of this approach or if anyone has done this?
