Best way to repair hairline PVC crack

[rat3]

Hi there. I have an outside 3/4" sch 40 PVC T that has a hairline crack in it. The line isn't always charged, but when it is it runs around 70 PSI. Removal of that T will have a bunch of secondary implications, so I'm looking to repair in place.

There seem to be a lot of approaches for patching PVC. The big question I have is what's the best approach for a line that needs to handle pressure? Would love any insight/experience folks can offer. Solutions I'm considering:

• Idea 1 - Cut a portion of 1" PVC and use pipe glue to "weld" that "PVC patch" over the cracked portion. It'll undoubtedly hold, but will it stop the leak?
• Idea 2 - Apply baking soda + CA glue to the crack, mold and push it into crack with a putty knife, use an activator to cure it. Sand that down to smooth, then do idea 1 over this patch for additional strength. More complex, not sure if the CA glue will add anything... the crack is slight. Maybe I dont even need the baking soda?
• Idea 3 - The bottom of the T is a 1/2" FPT fitting (drain valve). I could try and go through that hole and apply some epoxy to the inside of the crack. However, access is up from low, hole is small, and it'll probably be challenging.

Appreciate any thoughts or insights people can offer about fixes that work. Thanks!

Best option is to cut out and replace. Also plastic threaded female is a crack waiting to happen.

Dremel to open the crack is a good idea, will add that to my thinking.

Cut out and replace is an option but last resort. The T is part of a larger circuit that will involve a much more extensive and rework (extends into pool plumbing). I can do it, but I'm not going to if I don't have to. The T is non-critical (secondary to pool plumbing).
