Ok so outside we have a pool furnace that we thought was broken. We took the tap thats on the gas pipe next to the kiln out to see if there be any flow, and there wasn't any. The rest of our gas appliances work fine, but this pipe have no flow. Could their be another valve somewhere to be exact closed? Where could it be located, and what would it look like?
Answers:    There may be a second queue at the meter with a cutoff tap. it may be at the back of the house in the vicinity the pool heater.
There is the possability that near is a second meter for the pool only.
start from the starting point source of the gas line, the meter? and merely follow it from there.
you'll find it eventually
