Ok, the last several Rheem water heaters I've installed have had this insert in the dielectric nipples. I didn't get the memo on this. Could be that it unexposes the water to the deadly Fe/Cu connection on the very ends of the nipples. Not sure. It does, however, totally prevent me from being able to screw on my copper female adapters onto the nips. I've started pulling them out and tossing them. What's the deal on these?
