Small/Disappeared Leak in New PVC DWV

[Hambone8780]

Hi folks, when doing my water pressure test I noticed a very small leak in 3" PVC in the crawl space. Interesting, it stopped leaking after I finished filling up about 25' of water, and didn't leak for about an hour when I drained the system.
Is this a thing, for leaks to resolve themselves? It will be buried in the dirt, so I'm not overly worried about it, but I do need to pass inspection.
On that note, is there an easy-ish way to repair the joint? It's at the bottom of a long sweep el, in case that matters. I'm considering using a leak-b-gone ring, but would love an experienced opinion!
Cheers,
Rich

Its illegal to repair a joint. many times on ABS Ive seen guys glue around a hub on a leaking joint they just build up glue not supposed to though.

Its a lot easier to remove and replace the fitting now if for some reason the PVC cement didn't take or the fitting cracked.

Thanks Jeff! Is the code approved option to cut it out then?

Yes, So if leak is on top and a small drip under pressure I can understand the frustration. but its not allowed I dont nessesarily see the harm though . `

Experimental idea: Empty the water. Draw a vacuum. Let the leak area dry a bit, and then suck in ABS glue. I am not a pro. I have never tried this. A wet-dry vac might be a good source of vacuum.
