We installed a laundry sink in our laundry room and wanted to connect the sink drain line to the washer discharge wall mount hole. Ours has two holes and since the washer is already occupying one hole, we figured we'd use the second hole for the sink drain. Is this acceptable and also, what fitting do you use to connect a PVC sink drain pipe to a flexible type hose that can bend to reach and serve as a drain hose?
