I found the screen from my kitchen faucet aerator in my sink. I didn't know what it was at the time and I threw it away. It had obviously broken and fallen out. Can I just buy the screen part and put it back up there? I don't know the faucet brand name.
Thanks,
Jane

Go to Home Depot and purchase new Aerator. Unless you have some high end faucet, or unknown brand, they should be compatible. Back to you. Milo

Hi jane and welcome to The Plumbing Page at AskMeHelpDesk.com
To add a bit to Milos post. Look on the end of the spout. Some have inside threads and some have outside threads.
While most spouts have outside threads it's always best to check. Good luck, Tom

Hi. You will be able to buy the whole screw on aerator at any hardware store. I just bought one and it had a whole bunch of adaptors so that it will fit any kind of faucet. Good Luck.
