DIY Fix Bathroom Faucet High Pitch Squealing While Turning Water On- QUI...

This can go on and on for months and even years if you don't do something about it. I always like to stop from the top down approach. Meaning, easiest to hardest or less invasive to most invasive in hopes to find the problem right off the bat or not as far down the line. This was a very easy fix fortunately. It appears the screen in this faucet was doing exactly what it was designed to do. There were some small plastic chips sitting just inside it which was causing it to squeal or whistle. It was readily apparent once I removed the spout's screen. If you are going to use vice grips, you may want to put some kind of barrier in between the teeth of the vice grips and the spout filter receptacle so as not to leave teeth marks in it when done. Sometime a rag or towel will do the trick.
It's very fulfilling and satisfying when you can make someone's life a little bit easier by helping them or fixing something that isn't quite working the way it should. If you have an old faucet like the one in the video you may want to consider an upgrade like one of these below.
