During my basement remodel I have removed the existing line coming into the basement because I want it moved to another wall. I have a 50' roll of 3/8" soft copper tubing (never used) given to me. I am told it is ok to use. Why I ask is that the existing running up stairs to my central unit and what I removed seems to be 1/2". Previously the line split at the regulator. Coming off of my tank I have a regulator, then also one just outside the house where it the lines split. One line going upstairs then the other was going into the basment. Only my upstairs is on the central unit. Is it ok to put the 3/8" into the regulator where I removed the 1/2"? I am sure it has something to do with flow or volume. I don't want to create a bottleneck or mess with the regulator since it is set for the 1/2" already. Not usre it matters, but is why I am asking. I will call the gas company I use, but was wondering what thoughts anyone else might have.
Thanks
