Customer called us out for no hot water, looked at unit. It is nine years old at the end of its life expectancy. Looked at gas meter outside on side of home and it was locked out. The customers did not know that Atmos was their gas provider. I asked them to call. Atmos said they could come out Monday to test the gas and turn it on. I did explain if Atmos detects a leak , They will need to call us back to do a pressure test on the system find any leaks , code updates and permit will be needed at that time.
