Hi, I have a clarification question for you guys again:
In the plumbing section, it states that the water main shutoff valve should be identified, but that caution “must be exercised with old shut-off valves, as they can easily leak when they have not been operated in some time.”
Does this mean that we are expected to operate the shutoff valve, or merely look at it to identify it? Most other sections of this course have indicated that we are not supposed to operate shutoffs of any sort, but instead just identify the location and condition of them.
So what is the NACHI recommendation for the water main? Do I test the valve or not?
