Hi! I am not really sure what I am doing, But I want to run a new gas
line to my garage, for a new garage heater. I have a 1 inch gas main.
It feeds : A gas incinerator, a boiler, a water heater, and a few gas
lamps. I want to see how big the pipe should be. Is there any
general rule of thumb for how big the pipe. Again, I really dont know
what I am doing. I just want a rough estimate, so I can make it work.
I am not really sure, I think I might be able to just drill some
holes in the gas pipe, and tap it off.
