My main line from the gas meter enters the house with a 1" flex conduit connected to a union, then a reducer to 3/4" black pipe which splits to two legs extending in opposite direction in my basement. They eventually meet in one area, but connect to differing areas. One 3/4" leg extends to my boiler and Ts off to my garage. The other leg extends to my water heater, my dryer and a capped off pipe in case I want to install a gas stove. If you were to see the cluster of pipes, especially as they meet in one area, it looks like a bad roller coaster design. Therefore, I wanted to remove the two 3/4" legs and run one 1" leg and teeing off to each area creating a more pleasing look and eliminating misc. run on pipes.
Anyone see a problem with going to 1" black pipe?
