I want to move my daughter's 40 gallon gas water heater from a closet in her small kitchen to her garage. One potential problem is that the vent pipe for this water heater is concrete pipe. I have purchased and sent to a laboratory a sample of the pipe collected by pressing wide Scotch tape against the pipe (while wearing mask and gloves). I am in the process of preparing a Statement of Work for the completion of the water heater move consisting of tasks that I know I can complete (e.g. installation of a protective bollard and the hot water stand at the garage installation). In the advent that the lab reports that the pipe contains asbestos, who do I get to perform the removal? I want to remove the existing closet in her kitchen in order to have room to install a larger refrigerator. In order to do this I need to remove at least the length of the pipe between the old vent hood and the top of the dry wall above the old water heater (less than 24"). I would accept leaving the old vent from the top of the vent to the vent cap if that is allowed by code. Any help on this would be appreciated. Jim Houston
