Due to my kitchen design I cannot put my dishwasher next to my sink. Running the drain to the disposal would require me going through the 2 cabinet next to the sink and make a 90 degree turn. I have a wide open wall cavity behind the dishwasher and the basement below is wide open. I plan to run a 1 1/2 inch drain with p trap and air admittance vent to the sink drain in the basement. My worry is the pressure from the dishwasher drain washing out the p trap. Should I put a 90 before the trap to slow the flow down, and or use a deeper trap? Thanks in advance.
