Mr. Inspector
SAWHORSE
I inspected a lot of small one bathroom occupancy's where there is only one toilet room and they only need tempered water for one lavatory. Most of the time they use a small single point water heater under the lavatory. I'm always told that I am the only inspector that ever required a water temperature limiting device that conforms to ASSE 1070 for this. This seems to be true because I always see many existing lavatories with a single point water heater without this required temperature limiting device. Am I being too strict about this?
