I'm installing a tankless water heater to replace my old 1968 water heater. I'm installing it in a different room (next to the existing room) and so I have to make minor changes to my plumbing. I'm connecting the new tankless water heater using 3/4" copper pipe which will connect up to my galvanized plumbing under the house. Eventually, I may replace more lines with copper.
So now I have run copper up the wall and out to where it will eventually connect to the tankless but the ends of the copper have to be threaded and will thread into the brass coupler connection kit that ultimately hooks to the tankless.
Everything was going smoothly until I test threaded my fittings into the brass kit and they don't screw in very well and I was afraid I would strip the copper. The copper fitting will screw in 1/2 turn and then stiff where as a galvanized pipe will screw in 5 full turns before getting stiff.
This is a photo of a similar install valve where my copper line will connect at the bottom and the top connects to the tankless via a coupler.
