Is it ok to have the drain hose of the dishwasher just set into the kitchen sink and set in place, or do I have to merge it with the drain under the sink?
I am leaving this apartment soon (with my dishwasher), have a huge sink, and don't care aesthetically if there's a hose.
Thanks!
I can only think of three options here...
The first (less optimal) option, is to raise the discharge up and allow it to flow down to the drain connection. In this scenario, you'll want to have the discharge tube go up to an air admittance device (AAV) or air gap. From there it should flow downhill (1/4" per foot), until it reaches the garburator connection.
The other option, is to discharge the dishwasher to its own drain. Install a properly vented standpipe near the dishwasher, and connect the discharge tubing to that (follow local plumbing codes).
The last option is to run a drain line under the floor, and attach to the sink drain below the floor. Install a trap near the dishwasher, and run a proper drain that tees into the sink drain (follow local plumbing codes).
The reason for the high loop or air gap in dishwasher drains when installed below the counter are because of the risk of drain water being pushed back into the dishwasher. If you have a clog in the sink and don't have that high loop, water can drain into the dishwasher and flood out your kitchen. So with a countertop dishwasher, I don't see the need for the high loop since the drain hose is already above the level of the countertop.
Best Answer
When the dishwasher goes to pump out then the pressure will move the hose possibly blowing it all over your kitchen.
Think of a hose left on full without anyone holding it.
You will need to clamp it down somehow and even then expect some splashing.
Good luck!
