Forumites, A final flashback on this item: One of the members of the TC on NFPA 20 remembered this why:
1. Relief valves can be slow to open. Anecdotes were brought to the committee of sprinkler and standpipe systems blowing out because the relief valve did not open fast enough when the pump was turned on. 2. Relief valves that are piped to atmosphere waste water. 3. Relief valves that are piped back to pump suction really don't release pressure. Thank you all for sharing your views.
