There won't be one shred of old copper in the globetrotter when I get done .I apologize for any confusion .
There are at least 3 different sizes of copper in the old girl
I just found that when I asked questions I confused people .I'm not sure my buddy Syd still knows what I'm looking for .He hasn't called me back. I was trying to get valves and fittings from him at his cost.
I originally wanted to replace every thing as it was .If i can get the parts fine if not I'd be better of with larger diameter pipe .
One last story
I originally went into home depot looking to replace the regulator valve that I mentioned in another post. I showed it to the man at HD .He asked me what it was .Then he told me they don't make it in the size I needed .In the end he had no idea and I never found it on the shelf. Since then i have found a few other sources of plumbing supplies
