I am replacing an old dishwasher. I would like to know if I should add a one-way valve to the drain hose, to help prevent water from the sink from flowing into the bottom of the washer.
I have a loop in the drain hose going up to just under the bottom of the counter, but some water still comes out of this hose if I leave the end open.
There was a blue, hex-shaped plastic connector in the old drain line, but this passes water both ways. I think it may have been just an adapter.
It's recommended that you make a "high loop" with the drain line. Fixing the tube so that it makes a hump above the top of the disposal. Taping the dishwasher drain line to the side of the sink is a good way to do this. That should keep water from draining back into the dishwasher.
Without a doubt. The loop only works if the sink is never full of water, which
will drain back into the dishwsher tub. You need a check valve. New machines do not
require as it is built into most. You need to be sure.

Taping the hose to the sink will not work. When the sink is filled with hot water the heat will soften the tapes glue and the weight of the hose will pull the tape away from the sink. A better way would be to mechanically fasten the hose to the cabinet. Even a simple screw in hook and a wire tie will work. Just be sure the hose doesn't kink.
