: Can anyone explain what components make up the Johnson Tee and how all the parts fit together?
The dishwasher drain is run with 1/2" copper with at least a 42" riser where it turns back down and connects vertically into a Johnson tee. The tee allows for the 1/2" connection on top, with a vent to the outside on the branch, with a regular 1 1/2" connection going down to a P trap which is vented normally. Check with plumbing wholesale outlets for availability.
