I am remodeling my kitchen and would like to relocate my sink and dishwasher. I think if I get the sink vented correctly, I should be able to hook the dish washer up with no problems. Can I use the trap under the sink and just run the drain pipe from the trap over to where the sink was and hook up the drain pipe there? It would be about a 10 foot run. Thanks.

This should be fine. I'm thinking gravity might be a problem. You may want to put the p trap at the old location, so the plumbing is up close to the new sink. But it may smell after awhile. If you are using a disposal just make sure the pipe is slanted down. Another option is break out the wall at the old location and move every thing down lower. Then you can have the trap at the new sink.

I like your first suggestion but if I did that, I would lose my down angle from the disposal. What do you think would happen if I were to raise the pipe coming 'out' of the trap as long as I stayed below the disposal drain? Also, could I be setting up a situation where the water wouldn't drain properly because of a lack of venting in the 10 foot run? Thanks again.

And that should be your only option. The other way you're setting yourself up for clogs and really bad smells. Plus being so far otta code it's not even in the same zip code.
Open up the wall and extend the arm and stub out down to the new location.
I hope you're using 2 inch for your drain line. At 10 feet your slope would be 2 1/2 inches at 14 inch to the foot. However, if elevation's tight you may drop to 1/8th" to the foot giving you 1 1/4 inch slope. You may wish to install AAV,( Air admittance Valve) just after the trap to help with the venting. And speaking of traps I suggest you come off the wall stubout with a wye and hook the disposal up to its own trap and the tub up to its own also. Regards, Tom

If you did I would keep it at least 2in below.

I am picturing this in my mind before I buy all my new cabinets. It appears that I would have to have my lowered 2" line running through the rear of the base cabinets following the wall. Am I on the right track? Thanks for your help.

Has anyone ever seen or themselves run a drain pipe along the wall with cutouts for the pipe cut from the rear of the base cabinets?
