Sealer for 4" ABS pipe leak

[stans17]

My 4" ABS is leaking at the joint. Vertical pipe is leaking at the joint where is goes into a cleanout Y. The bottom of the Y is in the concrete basement floor so cutting it out and replacing is not an option. It doesn't make any sense that it would leak in a vertical run, yes I've removed the cleanout plug and the pipe is clear. The only option I see is using some type of sealer on the joint that is compatible with ABS. Thoughts on using ABS cement after cleaning with solvent. I tried to upload a couple photos but no luck., Thanks

Tie a cloth farther up on the pipe to see if the water might be coming from higher.

if its on top of c/o its usually not bad to glue it up put several coats on it letting it dry between coats.

Plumbers epoxy have had very good luck with it. Tried different brands all have work.

Never tried any of those epoxy putty they say it even patches potable water lines something Ive never dreamed of trying.

It's not coming from above, definitely coming from the joint at the Y. Doesn't make sense it would run uphill to the top of the joint, possibly a crack in the pipe. I'm going to clean and reglue then use epoxy putty after the glue dries.

I finally found the problem! The 4" ABS is cracked all the way around at the top of the hub on the Wye. This thing is located behind some shelves so I was on my knees under the shelves trying to stop the leak. The plumbers epoxy wouldn't seal the crack because I couldn't get it dry, seemed to be just enough water seeping out to keep it from sticking. I bought a small tub of Flex
Seal paste and that stuff worked right through the wetness. Hopefully it will last long enough for me to tear out the shelving so I can get to it to replace the pipe. Thanks to you guys for all of the .
