Low Water Pressure Only on Kitchen Faucet
So yesterday my dad and I replaced the aging faucet on our kitchen sink. To do that we had to replace a hard line for the cold supply which was tapped to supply water to a filter for drinking with a flex line connected to a short hard line, which we stupidly reused the old pipe tap (which we found had flooded the kitchen with a leak this morning). Dad went down and bought a T-fitting and after battling off leaks for at least an hour, I stopped them, only to find the water has reduced to a dribble from the faucet. I'm convinced that the valves (which have been in place since 1992 when they bought the house), have failed because it took some significant force to close it far enough to stop the water flow. And it's now stuck half closed, allowing only a little water through. Dad said he wants to avoid replacing the valves because we'd be knee deep in something other than water if pipes unscrewed further back in the wall. And getting a plumber is financially out of the question.

Short question: What on earth happened to suddenly reduce the pressure to almost nothing after cycling the valve a couple of times?

90% of the time the filter in the new faucet is plugged up with crud. Unscrew the aireator on the faucet and see if the pressure is back.

If it's a pull-out hose type faucet there is often a screen between the hose and the faucet head--

Let the water run for a bit without the screen to blow out any more debris.---Mike--

Is it just the cold water side? if it is, it is probaly the stop under the sink some times the washer comes off when you close the valve if that is the case replace the valve
the same could happen with both sides at the same time but I would clean the aerator first

Yeah, the rubber washer inside the valve was 100% gone (no wonder the water wouldn't turn off). It found its way all the way up into the faucet and was never to be seen again. Tried blowing it out with compressed air, no jive. completely stopped up.

OH BOY! Time to get creative. Maybe just change the supply line. Might be able to send a 1/4" cable up (or down) the line if you cut the bulb off. Duct tape the strongest shop vac you have to the line. Teflon tape and Rectorseal are your friend
