I have very cramped plumbing on my return line after the heater. I have a Stenner pump ready to install and I'm just a little stumped on where the best spot to put the injector would be. A slip tee is pretty much out of the question with the tight quarters so I need to find the best place to drill and tap the injector.

I don't have any surface returns. The only returns back to the pool are either through the water feature (sheer), or the in-floor cleaner. Complicating matters is the placement of the deck chlorinator feed which either needs to remain open allow some water through and keep it flushed out or else needs to be totally capped and drained. Would putting the injector in a place where some liquid chlorine would flow to the deck chlorinator cause issues with mixing (trichlor was used before)? I have keep the valve at the lowest possible flow setting to the deck chlorinator if open, otherwise it overflows.

Any help is appreciated.

The deck chlor is an in-deck chlorinator that you drop tablets into. It sits in the pool decking and feeds directly into the pool.
Have not seen this but as you state earlier it Is downstream of the piping for the infloor cleaner. Just plan to remove the chlorine tablets from it once the injection is set up and let it flush real well. The LC will be in solution by the time it gets to the deck chlor system.
