I'm in the process of re-doing my system.  I'm replacing everything except for my heat exchangers.  My questions is, I will be replacing my 3/4" line with 1 Inch.  My 3/4" connects to the 1" in/outlets on the HX in my furnace.  I have a reducer on the HX that takes it from 1 to 3/4 and then there is about 5 inches of 3/4 copper pipe that then connects to my 3/4" pex.  I really don't want to mess with taking the reducer off and soldering a 1' coupling on.  So what I was wanting to know is if the short lenght of 3/4 copper will reduce my water flow enough to hurt the performance of my system?  Any advice is appreciated.  Thanks!

Here's a picture of the coil.

I would just get it done.  Heat it up, pull it off, then slap a new 1" sharkbite elbow on there and be done.  You know it's the right thing to do!!  Here is your pep talk!  You can do it!!

CLEAN CLEAN CLEAN, the wire brushes meant for copper pipe are great, if no brush then use steel wool, more flux usually isn't better as too much can actually cause voids, heat just the outer part of the connection, not both pipes.

Old plumber/pipefitter down the road actually wore white cotton gloves while soldering, claimed even the oils on your fingers can bugger it up.
