Kitchen sink basket drain leaks. installed new kitchen sink and two new basket drains. one keeps leaking. I would find it leaking, so I tightened the lock ring. stopped for several days. then leaked again and lock ring was loose. took it all apart, added plumbers putty a little thicker than before, reassembled, tightened the locking ring and all good....foe a few days. again the leak came back and ring was a little loose again. What gives. is there not a gasket that replaces the putty? Puddy does not seem to be getting very hard.
The putty should never get hard. That is what allows it to to its job.
You might disassemble and verify if the mating surfaces are flat and true to each other. I usually apply the putty thick enough that I get a bit of squeeze out. Doing it that way has let to some additional clean up, but never any leaks.
What type material is the sink? Stainless steel? Plumber's putty is only recommended for SS.

Not for porcelain??
should be okay for porcelain, I believe plumbers putty should not be used with granite/stone sinks. Silicone should work....
It is okay for porcelain, it was rhetorical question.
Strange that once tight the putty wouldn't seal up. Seems to me you may have a cracked nut, stripped drain or never really got it tight to begin with or it would not loosen up as there are no moving parts and the movement from cold and hot wouldn't be enough to get it done
Assuming the paper gasket was installed prior to the nut being secured, I imagine the looseness developed as the plumbers putty continued to be squeezed under pressure. I normally retighten those type of connections several times over a period of time prior to putting them into service.
Thanks, stainless steel. new basket drain. it is the side we rinse dishes. wondered about the hot/cold.

I've seen that more than once.
