What should I do if ABS water pipe leaks?

ABS pipe is an acrylonitrile-butadiene-styrene plastic pipe, which is bonded and connected. According to what you said, it will get worse and worse to maintain with perm. A better way is to buy ABS glue, cut off the original leaking place and connect it with suitable connecting fittings. Pay attention to shut down the system when gluing, and the connection point should be in a dry state. When applying adhesive, the inside of pipe fittings should be coated first, and then the pipe ends should be coated. After coating the glue, align the ABS pipe with the connecting pipe fittings, insert the pipe, and then rotate it gently with the rotation angle of 15 ~ 30. After connection, let the pipeline stand for a period of time without applying stress, which is called static curing. If it is spring and summer, the static curing time shall not be less than 3min.

If the bonding is troublesome, you can also buy the copper ferrule connector used on the aluminum-plastic pipe with the same specification as the pipe, insert the pipe into the ferrule connector, and tighten the lock nut.
