I'm doing a kitchen remodel and need to add a new gas line and water line for the stove and pot filler. So far, I have 1 estimate. After recovering from the shock, I have decided to get some more estimates. Before anyone starts to worry, I AM NOT going to play with the gas or water lines myself. I would like to get more information and I'm turning to the experts for help.
The gas and water are both accessible in the attic above the kitchen. The plumber I got the estimate from was talking about having to drill holes for the copper and using flex for the gas line. My questions are:
For water in the attic, does the copper run through the joists or can it go on them?
For gas in the attic, are there any issues with using a flexible line?
I live in California - home of the earthquake building code. I realize the scope of this job but just want to have the knowledge base to help make good choices with the professional that will do the work for me.
Thanks for your help.
