Thank you for your reply. I’m really ignorant of the finer points of the issue but I too lean toward the brass fittings option. There is another school of thought ( I have no idea of its accuracy) is that the dielectric nipple is too short to effectively negate the the electical issues involved and recommend a 6″ brass nipple instead. Because I am clearly just an interested home owner, like others I’m searching for industry best practices for the maximum potential for success. But as with many topics such as these, there are so many options and opinions I lean toward doing what other, much more knowledgable folks are doing based on their experiance in the field. This is a great format for learning.
