Loss of pressure after tightening nut

My shut off valve was leaking. The plumber told me to tighten the nut behind the valve. I did this. The leaking stopped. However I lost some pressure. The plumber said I may have closed the valve a little While tightening the nut. He said to loosen the nut and hold the valve. I'm not sure I understand what he meant. Suggestions?

The internal washer may have come loose.. Close the valve and reopen it..

There is no reason if the valve is open and tightening the packing nut as you did to loose pressure other then the internal washer issue.. Its common..

Let us know..

Still no pressure. What's weird is that it was just the cold water that was leaking and now I have minimal pressure from both!!

remove the aerator at the faucet spout.. You have crude in there im sure.. Clean the aerator or replace it..

But look in the screen when you remove and see whats there... Washer material? Blue/white particles?

Reference only....

I did that. It worked. The plumber had called me back but did not tell me to look at the colours. I think I saw a few blue pieces

good job.. Blue pieces are usually dip tub and/or anode rod material from the water heater..

Have you recently flushed the heater or did some work where the heater needed to be shut off?

Check all the aerators in the home..
