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?

  • Well, first remove the plastic plumbing by unscrewing the lock nut - which is that big white flanged thing. Then see if you can drop that plastic outer cup and tap free the basket. – Carl Witthoft May 16 '16 at 13:24
  • @CarlWitthoft Hey Carl - I had the plastic pipes detached this morning the plastic cup is definitely fixed, just not sure how. It won't come free by twisting or tapping it. – Rob Sobers May 16 '16 at 13:28
  • I'm tempted to suggest a bigger hammer :-) . Try putting a pry bar (or paint-can lid opener) between the sink and the top of the plastic cup to see if it's snap-on. You sure you can rotate that plastic cup? – Carl Witthoft May 16 '16 at 13:32
  • @CarlWitthoft The plastic cup spins with ease. When I turn it, the screw that attaches to the strainer also turns (unless I hold it). – Rob Sobers May 16 '16 at 13:38
  • Advice from May 16, 2016 was solid. I managed to get one off with a very big screwdriver wedged sideways and the second one I drilled out from above. – Rod Jun 20 at 15:12

this looks like a chinese unit one of my granite suppliers used to use. they are the biggest piece of junk on the planet. if i remember correctly, the small screw in the middle acts as a retainer for the whole unit. you have unscrew it from above, and it holds the whole thing together. the problem we had was that the screw got locked into the metal insert thats in the lower plastic section and just seizes right up. our solution was a heat gun. just melt the lower bowl and keep pulling it out in chunks until you can get a grinder in and cut the bolt. then throw everything away and start again, using a quality metal strainer assembly

  • I was about to say this... but felt like he had kind of figured it out based on his last comment (the screw... also turns (unless I hold it)). – Ben Welborn May 16 '16 at 13:44
  • Yea, I have one similar to this and the screw broke and it leaked under my sink for weeks probably without me knowing. – Off The Gold May 18 '16 at 13:14
  • Screw was locked and we sawed the plastic section off. Replaced with a full metal strainer. – Rob Sobers Jul 24 '16 at 2:36
