'76 Overlander Shower/Copper Tubing
I need to replace part of the copper tubing going to the shower faucet on my 1976 Airstream Overlander. Most of the copper tubing in the Airstream is 1/2 inch; however, a section I had to repair under the sick was 5/16. Before I remove the section behind the shower, I want to determine the size of the tubing so I can buy the correct fiitings. I have been told that all of the smaller tubing behind the shower is 3/8. Does anyone know whether or not the copper tubing going to the shower faucet is 5/16 or 3/8?
