DW high loop...is this for the flex hose or drain pipe?
Comments (3)Ditto. The drain hose coming out of the dishwasher needs to go high (up to the countertop underside) and then slant down towards its connection to the hard plumbing. Just have it go high, and you'll have your high loop. Up to the counter and then down to its connection. (a Tee or a Wye in the hard plumbing.) Secondly, you can shorten the hose if after going high there is way too much left over. When the DW pump turns off, at the end of all the draining, remaining water can fall out (by gravity) from a large part of the hose. But this is not crucial for the high loop to be a high loop, or for the DW to work. It is a little bit of optimization. There is no advantage for extra hose to lay on the cabinet floor. Just because the DW came with a long hose doesn't mean it has to stay at that length. In case anyone reading this has a DW ten feet away from the plumbing drain, I'll add that the high part is right_near_the_DW, close to the DW and not close to the hard plumbing. Most DW are next to the sink, so this is not a concern for them. When your DW is across the aisle and your drain hose has to go around two corners, behind the cabinets, it runs ten feet. Then the hose has to go high right at the DW. Now, connecting to the plumbing: This could be before the disposer. It usually is. When one has no disposer, the connection is right before the sink P trap, i.e. usually right under the sink strainer. There is no logical link between GD and DW; they are independent and their drains don't need to be together. Cheri, HTH, and I wonder what you meant by ".... the standing drain that the GD and sink are connected to...." -david...See Morehigh loop in DW install
Comments (14)I have a Miele like sshrivastava and it is not next to the sink. It drains directly down through the floor and not into the sink plumbing. It doesn't need an external air gap(the kind you install and have the top of it exit on the counter. The air gap sshrivastava is talking about is called a vent in the user manual and it is inside the DW. It is simply a plastic cap near the lower spray arm that you snip off with scissors. I used mine for several weeks without it cut off and didn't have a problem, then decided to cut it off anyway - made no difference. Miele's can hold the water in and won't let water run back through the drain line....See MoreDishwasher drain question
Comments (6)I suggest rerouting the hose to eliminate the sag. It should not sag between the highest loop point and the plumbing connection. The placement of the T-connection contributes to the sagging. As per the answer in the plumbing section, the correct placement is on the line coming down from the left-side sink bowl, positioned so that it's upward and higher than the P-trap....See MoreDishwasher Drain Question
Comments (1)Actually you could have used the correct drain application from the sink on the right and lowered the crossover and attach to a "T" just above the trap. However, to address your question, just shorten the DW drain line removing the loop below the right sink outlet, which in turn, removes what amounts to an unvented trap created by that loop....See Morelucypwd
