I need to put a laundry drain in a basement, but there is no access to any of the existing drain lines. There is a 4" cast iron floor drain approximately 5' from where I would like to position the washer/dryer. water stands in this floor drain about 14"below the level of the concrete.
Can I connect a 2" drain line from the laundry into the 4" Floor drain at about 4" above the existing floor drain, or do I have to locate the main drain and tie into that?
