Splitting Gas Lines in a Philadelphia Duplex
I have a duplex in Philadelphia that is currently being serviced by only one gas line/meter. I'd like to split these lines so that in the next lease, each tenant can pay their own gas. I've spoken with PGW (utilities company) and I have a general understanding of how the process would pan out (i.e. hire a contractor to split the lines, make sure new BTU amount is serviceable, and then call PGW to add the new meter).
But does anyone have any idea of how large and costly a project this would be? Any red or yellow flags out there I should be aware? Would it be wiser to just have each tenant pay half or a fixed amount of gas each month?
