I changed a stop cock that broke and had to isolate the water from outside to carry out the repair. Ever since I did that the problem has occurred. It seems like I need to set the pressure from the outside tap which I have tried without success

Help please !

Hi Catlike...

Your title only came up 1/2 way... please elaborate, OK?

From what I did get out of your post, I think when you shut the "stop cock" it kicked up some sediment that has gotten trapped at the kitchen sink faucet. Disassemble the faucet and clear the lines by running water for a second or two (cover faucet with towel)... check the washer or cartridge at this time. Reassemble the faucet and hopefully you are all set... ;)

If your toilet is having similar issues then you'll need to disassemble the toilet fill valve and clean the washer under the cap, OK?

Back to you...
