Renovating an in-law's family cabin that has old brass propane lines in the crawl space. There's definitely a leak somewhere, and the company that fills the tank won't fill it until we replace the 30 year old lines (understandable). What is the best option for residential propane lines in a crawl space that are exposed? Should I go copper, galvanized metal? I tried a quick google search, but wasn't sure what to search for and most of what I pulled dealt with tank to house, not interior. via /r/DIY https://ift.tt/2Cqsvna
