I have a gas pipe sizing question to which I have been unable to get a satisfactory answer. I would like to replace my current water heater with a tankless one. Because of the increase in BTUs, I understand that it will be necessary to increase the main gas pipe from 3/4" to 1¼" . The pipe coming out of the meter, however, is 3/4". I have read that it is not permissible or effective to go from a small gas pipe to a larger one. Nonetheless, the plumbers I have talked to have not explained how or why this permissible when connecting to the pipe coming directly out of the meter. Any help clarifying this issue would be appreciated. Thank you.
