I had an emergency request where one of the regulators on the meter broke and caused my hot water heater to run non stop and ran all of our detain out. When I called they got there in almost two days. They got there before it ran out.
I think that they most of the time they should deliver in my area in the same day so I can plan ahead. Instead in the summer time where it is less busy they deliver on the same route. Certain routes on certain days (all over the place) but economically should to be to you one area in all those tanks in that area. We can plan to when they are coming if we know where they are coming.
