Kitchens – Is the p-trap too low

kitchenssink

We recently installed a new sink and because the drain is in a different spot decided to replace the plumbing. This is the preliminary set up. My question; is the distance from the bottom of my p-trap to the exit pipe to great?

Don't mind the towels and baking dish we were just making sure we had no leaks.enter image description here

You seem to have way more piping that you actually need. Some points to be made reference this picture:

  1. There is freedom to rotate the whole disposer to optimize the piping.
  2. You should be able to cut off a portion of the disposer tail piece at (A).
  3. You should be able to eliminate part (B) and the elbow (E) to the left of it.
  4. The sliding connection part of the p-trap at (C) can be directly attached at the cut off end of (A).
  5. The other side of the p-trap (F) should be able to directly connect to the elbow piece at G enters the pipe at W on the back wall. Rotate the disposer and the amount that the elbow piece at the wall penetrates into the wall (W) to adjust the fit of the pieces going together. The amount you cut off of part A will be determined by what it takes to line up the opposite side of the p-trap (F) with the piece from the wall (G).
  6. Note that the plumbing piece that you currently have at (G/W) will most likely need to be changed because the coupling at (F) is not normally a slip type joint. A p-trap can be purchased that has the mating part for the joint at (F) as a part of a kit.
