I'd stick a 4" PVC drain line under the floor to accept the gland drippage, main drain, etc. Prob not a job where the test header would be in the pump room..... Is it feasible to stick a doghouse alongside the tank and put the pump there? If the floor is poured you may have that much ($20k) in the trenching and drain line.
For a Church I'm assuming a small vertical in-line electric with lim service controller? Those can readily be yanked out and carried down the hallway, or on a cart. glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Todd Williams - FPDC Sent: Monday, August 18, 2008 12:44 PM To: [email protected] Subject: RE: underground through building This is an existing project where the original contractor screwed up and was thrown off the job. One of my regular clients took it and asked me to help straighten it out. There is no way presently to avoid running under the building. The requirements of 6.2 are being applied. The pump room cannot be directly accessed from the outside. If they can get the pump in, they should be able to get it out as well. The room, while tight, is adequate size. The local AHJ is aware of it and has supposedly accepted the arrangement. Drainage is another issue we are working on. There is more, but not for this post Todd At 11:54 AM 8/18/2008, you wrote: >You've got a bunch of issues there. > > >Pipe under buildings: check NFPA 24, 10.6.1 PIPE SHALL NOT BE RUN >UNDER BUILDINGS. > >There is some allowance when it can't be avoided as listed in 10.6.2. > >Can the pump room be accessed directly from outside?
