I have a kitchen sink basket that's leaky and has a bunch of gunk caught under it. I want to replace it. All the instructions I see for removing and replacing a kitchen sink basket start by removing the lock nut underneath:
My sink, however, doesn't have a lock nut. The pressure cup is plastic and I have no idea how to remove it.
Here's what it looks like from the top. I tried holding that little center piece steady with a screw driver and tried to unscrew the basket from beneath, but it just turns and turns and won't loosen. Any ideas?
