   Dishwasher only requires hot.  Check with manufacturer and see how far you can extend discharge hose. If downhill probably a pretty good ways I would think.  Would want to make sure you have some loop to act as a trap for sewer gases. Just how far are you from a sink?

   I'm about 6 feet from the sink in the kitchen, but if I go into the basement and look for the sink waste pipe I'd be about 3 feet on the diagonal.

   You need to be sure the DW drain is properly installed to prevent backflow into the dishwasher if the waste lines should back up, and it must discharge into a properly trapped and vented waste line.

   You should be sure to follow the manufacturer's ionstructions as to drainage details.  If you run the drain into the basement to the kitchen sink drain, you need to add a trap before you join it to the kitcehn sink line (you shouldn't double trap the kitchen sink.)  And the new waste line has to conform to venting requirements.

   Why do you think we pay plumbers so much?  Just to look at their .... never mind {G}_______________________

   Fine to put it on its own 20 amp circuit.

   I have installed dishwashers up to 4' away from the sink and around a L shape cabinet. You are only running a 3/8" water line from the hot supply at the sink. Buy enough soft copper for your run plus about 2' extra, so you can pull the dishwasher out if it ever need repair. depending on the size of the hot water line to the sink, purchase a 1/2x1/2x3/8" stop valve with all three side being compression fittings. Drill  appropriate sizeholes at the back of each intervening cabinet, and run the water line through them the dishwasher.

   The electric can be run from the panel, or you can tie in on an existing circuite if it is not fully loaded.

   The waste line can be run just like the water line, but  run it to near the top of the cabinet next to the dishwasher, and then low for the remainder of the way to the sink base. At the sink run it up to the air gap, and then down to the waste tail piece from the sink. These tail pieces are made for dishwasher hook ups, and replace the current tail piece before it goes into the P or S trap. You need not be concerned about having fall in the discharge hose. The water does not drain from the dishwasher, it is pumped out. Check the installation instructions for the proper sixe hose and the limit of the lenght you can run. The hose from the air gap tohe drain tail piece is ussualy a different size than the one from the dishwasher to the air gap. Make sure you know the sizes before you start. Nothing worse than almost getting finished, only to find out you are short 18" of hose, and all the stores are closed :)

   Good luck with your install.

   Thanks Dave!

   How would you go about this if I can NOT get thru behind the base cupboards? There are drawers in the way which go all the way back, perhaps I could alter on of the drawers so it doesn't go all the way back.

   I was hoping there would be a solution I could apply in the basement since I have easy access to the sink drain run.

   Cabinet drawers rarely go all the way to the back of a 24" deep base cabinet. Pull one out and measure it. I think you will find it is, at most, 22" from the front to the back. The remaining 1 1/2-2" is all you need. The water line is only 3/8", and the discharge hose is ussually about 3/4" OD. or 5/8" ID. Buy some pipe straps to match the outside diameter of each line and secure them to the cabinet backs. There is also the area between the drawers. Even real old cabinets with wooden drawer glides have about an inch or more between the top of one drawer and the bottom of the one above it. Do a little measuring and you will find the space you need.

   If for some reason you don't like Dave's way (which I use), you can always hack out a huge portion of the cabinet sides (in the middle behind the toe kick a ways) beneath the bottom shelf height. I usually hack it out anyway to make cabinet installation easier.

   All you need is a vacuum break on the drain,

   If aestheically you can live with a 1" stub of 3/4" pipe out the side of your kitchen wall (functions as the vent also), simply drop the 1-1/2 drainline from countertop height into the basement, user the special dishwasher ABS fitting for the purpose with the DW input and outside vent right under the counter top, then no need to go behind cabinets.

   Edit PS:  There are also fittings that put the vadcuum break stub out the top of the counter, but those look really cheezy to me (little stainless louvered stub thingys, never have used one)
