If it connected to the sewer system, why in the hell wouldn't they allow it? Typical city BS. Of course, remember in the Navy, they were always on the high spot of the room.
I understand the "no floor drains" at home or tied to the ditch/storm sewer...but if they are tied to the sanitary sewer...then that should be OK and it's what I'm gonna do.
I am located about 40 miles east of Waxman and was required to put floor drains in both the Equipment room and the vending machine/changer/ storage room. The inspector told me I had to have it. In the end it worked out because I had to put the hot water holding tank in that area because of lack of space.
