I not sure about your system at our system we run 25lbs to reg at meter it cut to 1/4 pound I have to no all details. If you got 25lbs coming from road you can put a 2lbs reg at meter have meter set up for 2lbs and that saves on labor and pipe size.
Yes have them to put 2lbs regular at meter and a meter for 2lbs and it will save on labor pipe size and just one regular. PS work in natural Gas Piping for 22 years
