concrete filled steel bullards.
I had my home inspected and found this in the inspection report.
"There is no protection for the water heater. Under current building standards a water heater located in a garage must be protected with concrete filled steel bullards."
What are these and how much work is it to put them in? What would be the minimum I could do? The hot water heater is in a corner of the garage next to the washer. It is raised the 18" from the floor and is on a metal drain pan.
