Why the sudden drop in kitchen faucet water pressure?

[PFSLarry]

Just had strange occurrence and hope someone can please help.

Noticed a small leak under kitchen sink.

Wanted to troubleshoot shut off valves for possible leak, so I turned them off and on moved them back-and-forth some to check for leak. Nothing.

However, upon reopening both supply valves, hot and cold, and turning on the faucet, the pressure was suddenly close to nonexistent!

I know sometimes sediment can get caught in the aerator but could this be likely under this circumstance or most likely something else?

If likely, my faucet does not allow for access as far as I can see. Any thoughts please from professionals or those with much experience?

Thank you in advance!

Snapped the valve stem perhaps and valve remained closed.

check your valves it might be clogged up with sediment

Clogged aerators and clogged cartridges are two of the most common causes of low water pressure in a sink. Call an expert for an overall checkup.
