About 15 years ago they replaced my gas meter. When I got home from
work there was a note on my door for me to call and somebody would come
out and turn the gas back on. When the tech got there he tested the
line first. He hooked a manometer to the line. Then he blew into a
tube he hooked up to it. When the manometer dropped back down he
started looking for the leak. The leak turned out to be in the meter
itself. But the test was not some huge super-dooper thing. Just as much
pressure as he could get into the line with one breath.
