Product review (1 stars): Eastman Flex Hose Broke After Nine Months Normal Use.
Discharge hose almost lasted ten months. Just took out the one I got here Eastman 91227 flex hose and threw it away.  Cracked from normal use and water damaged the house.  Replaced with 5/8 rubber hose similar to auto heater hose from appliance section of the home improvement store and a $4.00 adapter fitting to attach it to the dishwasher discharge tube.  Probably should have done this the first time.  Don't waste money.  Do it right the first time.
