    I think it is 3'' in a 100', which would only be 3/16''. Anther way is to carefully buy DWV elbows. They are not complete 90 degrees, but just the right angle to give enough slope. More importantly, they have longer, smoother bends reducing the tendency to clog. You do plan to keep the trap near the sink?

    1/8 to 1/4" drop to the foot is normal,( 1/8 is just cracking the bubble on your level). On a 6' run you would raise 3/4" with 1/8" and 1 1/2" using 1/4"
    .
    Good luck, Tom

Drain placement on outside wall [ 2 Answers ]

I'm putting a kitchen sink next to an outside wall. The wall is 2x4 framing, and sits on a 2x10 rim joist. My question is, do I cut the hole for the drain through the wall cavity, or can I go through the floor, since it will all be enclosed anyway? My concern is that the wall is too narrow...
