I would also add that many of our industrial clients in areas other than the west coast are now wanting to capture (and reuse) any fire pump discharge.

As you may imagine the already high cost of a fire pump was increased by this requirement. sincerely, Ken Wagoner, SET Parsley Consulting 500 West Mechanic Street Harrisonville, Missouri 64701-2235 Phone: (760) 745-6181 Visit the website<https://linkprotect.cudasvc.com/url?a=http%3a%2f%2fwww.parsleyconsulting.com%2f&c=E,1,Y5zKJKPEh1mBEBqSR-VE9cUKl5y-eyP8BpvmE_5j9ZqW2eJbNphYzrCMBZ-2YuX6d-RRkHI4gQ1FV-cvOeCfRC58uZS9NiToZv2mx7909oCqLvCW_n5hDHeK&typo=1> On 9/25/2024 8:43 AM, Hinson, Ryan wrote: Not per NFPA 20.
