Sudden Loss Of Water Pressure / Under sink valve

Hi. A couple days ago I was using my kitchen sink and had a sudden drop in pressure and it's been that way ever since. There's no loss in pressure anywhere else in my place. The first thing I did was check under the sink and in the basement for leaks but everything was bone dry. Next I took off the aerator hoping it might just be clogged. There where some small, hard, black things stuck on it but not nearly enough to cause any pressure loss. Then, I was about to take apart the faucet to flush it out figuring there was a clog in it or further down the line but when I closed both the hot and cold valves under the sink the hot water kept flowing. My best guess is the guts of the hot water valve deteriorated for whatever reason and fell apart causing a clog. I'm thinking I should replace the bad valve then try and flush it out but i'm no professional and would like someone elses opinion. So my question is; what do you think?

It's possible that could be the case. In addition, it could also be a small piece of sediment or whatever that can't pass through, or is stuck in the cartdrige. Do you have another isolation valve on that line so you don't have to turn water off on the entire house?

Can you post some pics of under the sink of the supply lines and top of sink so we make sure we're talking about the same thing? Supply line valves can be sweated, threaded, pex, or sharkbite, etc. Throw up some pics, lets see what you got.

Also, while you have everything off, go ahead with your other plan as well and remove cartdrige. Give it a couple taps on your palm run some water over it. Can't hurt. Make sure it's clean and free of debris.

If you need more help, keep asking questions. Guys are here to help.

Sounds like you got a little project to do. Plan to diy or hire a pro?
