I'm trying to replace my kitchen faucet's aerator, but as I'm tightening it, it'll reach a point where it sort of "pops" and becomes loose, allowing me to tighten it again. I'm not sure if that's a bad sign.

Anyway, I thought it might be due to all the grime that's built up on the faucet threads, so I took a toothbrush and some oil and scrubbed it down pretty well.

Unfortunately, that didn't work. Taking the O-Ring out does allow me to tighten it completely, but that has a side-effect of causing the water pressure to be absolutely ridiculous.

So now I'm debating on getting some plumber's tape, or possibly running down to the hardware store to get a part or something to try and fix this. enter image description here enter image description here

  • Hello, and welcome to Home Improvement. Pictures of the aerator and that O-ring would be helpful. – Daniel Griscom Mar 29 '19 at 17:18
  • @DanielGriscom Sure, here you go. – Ezio Auditore da Firenze Mar 29 '19 at 17:24
  • Are you trying to use the aerator in the picture? If so, which thread are you using, the inside (female) or outside (male) thread on the aerator? Did you try removing the black rubber gasket but leaving the white plastic restrictor in? – Jimmy Fix-it Mar 29 '19 at 18:50
  • Note- that aerator is actually a combination device that aerates the water stream and also serves as a quick-connect adapter for a portable dishwasher... – Jimmy Fix-it Mar 29 '19 at 18:51
  • @JimmyFix-it I'm using the inside (female) thread, and removing the gasket lets the aerator tighten fully, however the water pressure is then too great. Additionally, the aerator I am replacing is functionally identical to this one, except I lost the gasket over a year ago. And I have a portable dishwasher. – Ezio Auditore da Firenze Mar 29 '19 at 18:53
