      The receptor itself must be large enough to handle the total discharge of the fixture without overflow. The only trap there should be is the one below the receptor. There is no specified length for the length of the drain to the receptor but common sense practice and best method should rule the day.
      2006 IPC states all indirect waste piping that exceeds two feet in developed length measured horizontally ,or 4 feet in total developed length,shall be trapped . so you would have a trap on the indirect waste and on the receptor drain connecting to the sanitary sewer . UPC is 5 foot in total developed length except for ice maker drains.

      the person that put the 3/4" diameter 20 foot long receptor drain does not have common sense when it comes to plumbing .

          if you look in the 2009 UPC illustrated training manual indirect wastes if the total developed length is 5 ' or more they want a trap on the indirect waste . 4 anything that has to do with food UPC calls for an indirect waste discharging through an air gap into a receptor which must be trapped because it is connected to the sanitary sewer .

            Got to find my book! Sounds like both codes allow double trapping provided it's an indirect connection between the two.

            And the few soda fountain rough-ins I've done we always had the indirect receptor almost directly under the designated area.

            If they move the service, they should move the receptor to underneath it in my opinion. Part of the service.

              it's not considered double trapping as the indirect waste is not a direct connection to the floor receptor.

              now if you want to call double trapping, look at all the jurisdictions that require a building trap

                If your person in QC wants to prevent long indirect runs from your soda dispenser equipment, there's a simple solution. Have him/her place a highlighted statement to such effect in the equipment installation instructions sent out with each dispenser, e.g.,
                Any indirect runs from said equipment over a certain developed length will require a minimum of 1-1/2" piping, w/drainage fittings and cleanouts, to terminate indirectly at an approved (trapped) receptor. Installations failing to do so will void equipment warranty.

                  They do it here also, on a soda bar in a cafeteria looks like a maze.
