I recently had a contractor put in a new sink and disposal along with the piping. The disposal tailpipe is just barely above the drain pipe, however the p trap doesn't go straight out.
- Is there a minimum height requirement that the disposal tailpipe must be above the drain?
- Does the p trap need to be straight out to the drain or can there be an additional elbow like in the picture?
- Does the dishwasher drain (smaller plastic tube) need to be above the disposal, or does that get pumped in without the need for gravity?
Thank you for the help!
