copper dishwasher drain help

[impulse]

I bought a new dishwasher and the drain hose is not long enough to make it to the copper transition. The dishwasher is a Bosch and where the hose is attached is not accessible leaving me with 2 options that I know of: use more corrugated plastic to extend whats there, or extend the copper closer to the dishwasher. My concern with the latter is that it is 1/2" copper which doesn't look thick enough for a drain. If I extend the copper, will I have a sizing problem? Plus I have to add 2 90s to get it where I need it. What is the proper way to do this?
Thank you.

you can replace the entire length of hose with 5/8 neoprene hose. or slip into the end of existing hose a short pc of 1/2"copper (5/8' O.D.) an a couple hose clamps. 5/8 radiator hose at your local auto parts store will do. Should have it at the hardware store as well.

make sure that you loop the hose up to the bottom of the cabinet, tie it off
then hook up to your disposal or y branch tail peice
