IS my Gas heating other Units
I live in a condo with 4 other units. The condo use to me rented weekly during the summer and the Land lord paid for the Natural Gas. He decided to rent all the units out yearly and the tenants pay for their own gas.
All of the lines come into the utility room from the meter with the same size pipe. Looks like 1 1/2 inch pipe. My gas line comes in as 1 1/2 in pipe then converts to a larger pipe aprox 2 1/2 - 3 inches. All of the other lines in from the meter stay the same size and go directly to their hot water heaters. I am concerned that my gas line is feeding the other units. How can I know for sure?
