Kitchen drain pipes run horizontal to the main drain. Will there be a problem with drainainge if there is a diagonal upward slope (3"-4" slope) to main drain? thanks in advance
Yes...it will create problems. My unprofessional opinion. How far does it go horizontal prior to hitting the vertical?
jadnashu..
thanks for the reply...from the p-trap, horizontal pipe is about 3-4 ft. before the pipe goes diagonally up (not vertical) maybe about 3-4 inches to connect to the main drain pipe...thanks..
If you can convince water tp flow uphill, your next project should be to design a perpetual motion machine, because it is supposed to be impossible also. To quote someone, "Don't lower the drain, raise the sink", or vice versa.
