Question regarding double wye usage
Posted by Dan Carroll on August 14, 2001 at 15:51:41:
I'd like to ask if a double wye can be laid flat (including an appropriate pitch) and still function appropriately receiving waste from the wye on each side. I have 2 toilets back to back that do not have room below for a straight-down waste configuration. I need to run the waste line horizontally and wanted to use a 3 inch double wye to receive each toilet and the center line in would provide the vent.

After looking at the double wye, I am doubtful that the waste will move with the correct fluidity when laid horizontally.

Thanks in advance for any help
