Hi all, First post, but I've been lurking for some time and have gained tons of information from these forums. I am completing a garage/workshop. This is certainly the biggest do-it-yourself project that I have ever tackled. I am in the process of finishing the gas supply to the garage. I have checked with the zoning commission, the local gas company, and my insurance company to be sure that I can do this myself. I have verified that the line is of adaquate size. I have run black pipe in the house to yellow plastic line underground and back to black pipe in the garage. I have pressure checked all work so far. My question concerns how I tee into the existing line in the house. The existing black pipe comes from the outside meter and supplies the furnace, two water heaters, two fireplaces, a stove, and a clothes dryer. I would like to tee into the line between the meter and the furnace where the line is the biggest (1" or 11/4" I think). Naturally, there are no unused tee's or unions in the line. Do I have to disassemble the entire existing piping starting from the far end or can I cut the line someplace after the meter, unscrew both ends of the cut section, and replace that piece with a couple of shorter pieces with a tee and a union? What would be the safe way to cut the existing pipe? Obviously, I would shut off the gas. Is a hack saw safe? Thanks for your input, Skyking1992

fittings for water plastic pipes can be put cocealed in brick walll withaut fear of leaking?
