I replaced my garbage disposal with a new unit and attached it to the existing drain with the manufacture provided straight outflow pipe. The new disposal sits a little lower than the old unit, which also had a straight outflow pipe. The result is that the outflow pipe is now angled about 5º down towards the disposal.
I'm guessing that's a bad thing as the ground up food sludge will pool towards the disposal end. What slope angle should I shoot for?
The level was just a touch too long to hold flat against the pipe, so that's why there's a gap. But you can see that the horizontal air bubble is just off to the T end.
The T connection on the left is a split 1.5" baffle. The connection on the garbage disposal itself is full rubber with a metal ring clamp, so it can flex to a wide angle if needed.
Is there a combination level + protractor + measure tool that could tell me how much I need to lower the T connection by? How would I go about dropping the T connection by such a small amount? I was imagining disconnecting the pipe and carrying it into a hardware store…

The top part of the tee is a slip joint. You may be able to loosen the nut and slide the tee down the tail piece to gain the slope you need. ( the tail piece is the pipe that is from the basket of the sink and is going into the top of the tee.)
If the tail piece is not long enough then you can buy a new tail piece that is longer and cut it to the correct length. The slip joint allows for some play so you can adjust it up or down as needed.
