I do not remember ever seeing anything that would prohibit pumps in a pit. I have also seen several pumps in pits (one full of water similar to the ones you are talking about). These would make me think that they were at least allowed in pits at some point.

We have a project with 2 pumps. This is an existing facility. These pumps are in two separate pits. One is diesel, one is electric. Currently, both of the pits are about half full of water as the sump pumps failed in both. We are trying to convince the owner to get these pumps above grade. It seems stupid to protect a $$million+ data center with a system, then rely on a $20 sump pump to keep the pits dry. There is a big retrofit at this site. Tried to do a site flow test, downstream of pumps, today and found this issue. So, just hoping to be able to find code/standard section that would prohibit this. Owner's first thought is to just make band-aid repairs. But, we are all concerned that this will happen again and leave the data center at risk. -- Travis Mack, SET MFP Design, LLC 2508 E Lodgepole Drive Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107 email:[email protected] http://www.mfpdesign.com https://www.facebook.com/pages/MFP-Design-LLC/92218417692 Send large files to us via: https://www.hightail.com/u/MFPDesign _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
