Sink drain line
I am about to start a major kitchen remodel. The kitchen designer has moved the sink (on paper) across the kitchen from where it currently is.
The floor will come up during the reno to run a new drain line across the kitchen to tie into the existing waste stack.
The home is a bilevel, so there is no basement, and no access from the rooms below.
So here's the question(s) -
1. The horizontal run of the sink drain line will be about 10 feet, but can only drop about 9 or 10 inches in that span because it will be in the existing floor. Is this acceptable?
2. Unfortunately the floor joists run perpindicular to the piping run I need to make. What is the accepted method of getting from the sink to the waste line? Notch beams? Drill beams and use a flexible line? No clue.
