Is my plumbing ready for a new dishwasher?
Hi, we plan on buying a new dishwasher but before buying it, I would like to make sure that everything is shipshape.
We used to have an old dishwasher but took it out years ago. The new dishwasher would go where the old one used to be, to the right of the sink. We also don't have a waste disposer.
Our RO faucet took the spot of the air gap for the old dishwasher. So, if an air gap is needed, it would have to go to the left of the kitchen faucet (there's a hole already there but it just needs to be made larger). If you check out the circled part in the picture I attached, the dishwasher had a metal tube connected here.
The installation instructions explain that there is an option to not have an air gap (see option B). It says to connect the drain hose to the waste tee. Question: where is my waste tee? Is it there and I just don't see it?
Should I use an air gap? Will it be a problem that the air gap will be on the left side while the dishwasher hose will be coming from the right? Do air gaps usually come with a dishwasher?
From my picture, do you see anything that will impede with the installation of the dishwasher?
Thanks for reading

Thanks for the reply. So, i disassemble the plumbing and replace part4 with something that looks like the part in your picture? If an air gap is needed, should I replace part1 instead of part4?

Local code will dictate the need for an air gap. You are from California, so you can bet your bippie you will need an air gap. At the least the dishwasher drain line needs to loop up to countertop level (under it) fastened to keep it there, then run to the adapter tee.

I bought the air gap today. However, I didn't find that piece for under the sink. I went to Lowes and HD. The closest thing I could find was this but our plumbing has a larger inlet size. Also, what they had at the store was too long and was only threaded on one end. Where else beside a hardware store could I find what I'm looking for?

So Monday I went to the supply store and they helped me understand that the new piece--which I've learned is called a dishwasher wye or tailpiece branch--could only fit under the left drain (where tailpiece 3 is). I also learned that what they sold was exactly what I had seen at the stores. I bought the piece but I made a mistake by cutting it too short. :/ It still fit but the nut and washer easily slipped off if I put slight pressure on it.
I reconnected everything with the new part anyway and noticed that it all looked lopsided. The wye was longer than the right tailpiece. So, when I went back to the store to buy another wye, I also picked up another tailpiece.
Once everything was in its place, I tested it out but found that there was a leak. The water was coming from the top of the wye. It has a tailpiece washer and the nut is securely screwed on the drain so I'm not sure why this is happening.
On the positive side, I cut the hole in my cast iron sink and installed an air gap. It took a long time for me to get through the sink but it was so satisfying to make it through.
