I am replacing the drain hose on our dishwasher. The old one was 10' or so. No knowing that, I of course bought the only one Lowe's had which is 6'. The old hose did a high loop on the side of the dishwasher. I also had run a high loop inside the cabinet before connecting to the sink drain. Are both loops needed? I have enough hose for one loop but not both.

Hi John...

A single high loop under the kitchen sink cabinet is all that is needed. It can hook to a disposal or a branch tailpiece... see image.

Thanks.

Mark said it. In addition to his answer: manufacturers install high loop on side of some DW just in case. But do as Mark said and you'll be fine.

With two high loops you have created a running trap in your discharge lne. One loop is all that's needed. Good luck, Tom

Thanks to all of you. I tried to rate your answers but the system would not allow it. Oh well.
