moving dishwasher drain pipe question
Hi .. i am adding a dishwasher to kitchen that did not have one before... the dishwasher will be about 8 feet away from the sink area .. i have already ran hot water pipe from under the kitchen (in the basement) wich ends under the dishwasher. I figured i could run a hole in the kitchen floor and connect the dishwasher water hose to this pipe in the basement... is that ok? my other question was regarding the drain pipe .. can i run a long pipe under the cabinet from the dishwasher to where the sink? or can i just put a whole in the kitchen floor and drop the drain pipe into the basement and connect it to sewer line .. is there a standard/code for this? thanks.

Your water connection should be fine but you'll have to check local code on the drain. Most areas now require an air gap installed in the countertop. Even before this code was implemented, the drain hose from the DW had to go up high and then drop into the drain connector on the sink. The DW drain has to have a trap included which is normally the one on the sink drain. Good luck.

If you go down with the drain, it must be connected via an indirect connection such as an air gap or open standpipe. This must of course be a connection into a trap, which must be properly vented.

thanks for the replies . .sorry, but what do u mean by airgap and trap? i see how in other homes the drain comes up and goes into the garbage disposer . .where would be considered the gap where is the trap? Are u saying as long as the pipe goes up into a drain, i should be ok?
p.s.
I hear about checking of local codes . .where /how do i exactly get my hands on the local codes? thanks again.

I have included a link to show you what an air-gap looks like. It prevents back-siphoning of the water.
The trap is the "gooseneck" or "U" shaped fitting in any fixture. Look under any of your sinks and you will see it. Normally connected right at the point the drainline goes from vertical to horizontal. The trap holds water so that sewer gas cannot enter the house. Normally a dishwasher fitting goes in the drainline on the house side of the trap. The fitting is usually a 1-1/2" X 3/8" tee with the small section on an angle.
