22" is going to be really tight, I took a picture of my set up and it is exactly 22" see attached photo.
There are three types of pool cleaners suction cleaners, pressure cleaners and robotic. The suction cleaner has a line plumbed into the suction side of the pump and the cleaner sucks up debris. For the location, you show with the T that would be a pressure side cleaner which uses the return water from your pump to propel the cleaner around the pool almost like a pressure washer. Normally if you were pre-plumbed for a pressure cleaner you would just see a pipe stubbed up out of the ground that was capped off and this line would be going back to the pool. I have tried many different cleaners on my pool and by far my favorite is the robotic style cleaner, and within the robotic cleaners I have tried 5 different ones (one of the perks of working in the pool industry =)) and my favorite is the Dolphin Triton
I do like the idea of doing a loop in the plumbing but it may be a good idea to have your pool guy double check. Another option is a vertical installation something like this Vertical Installation Finally I don't believe that valve is needed for any backflow prevention, normally you would use a check valve for backflow prevention and a ball valve is just used to control the flow of water to the pool, but normally on the pool returns you don't need to throttle the flow of water. This may be another thing to have the pool guy review. Best of luck and let me know if I can help in any way.
