We bought a KitchenAid dishwasher, but need a 12-foot drain hose, which I have been enable to find. The manufacturer does not carry one (I called) but the manual says it will take up to a 12-foot hose. My husband is reluctant to join two smaller hoses with a clamp because he fears leaks. Does anyone know how I can find a 12-foot drain hose, or someone who will custom make us one? Thanks.
