Does A Garbage Disposal Need A P Trap. It has to be there. If this is your first dishwasher or you don t have a garbage disposal with a nozzle you can set up the p trap with a special section that has a nozzle for attaching the hose. Remove the p trap waste line running from the disposal by using a wrench to unscrew the slip nut connecting the disposal to the trap.
The t joint is baffled and i am not a fan of this arrangement since it clogs quite often. The p trap is an important component of sink plumbing that prevents toxic sewer gases from leaking into the home.
Simply get rid of the garbage disposal and put a new sink drain and put it back together be done cool.

Simply get rid of the garbage disposal and put a new sink drain and put it back together be done cool. Wifey says she would like to keep the garbage disposal but i can t get water to flow uphill. The pipe that comes out of the garbage disposal is horizontal to the main vertical pipe before it goes to the p trap.
