I recently had my kitchen water shut off valve replaced. When the shut off valve is turned off for the hot and cold water, the compression faucet still drips. I shut the water off at the main valve outside and it still drips. Is there a quick fix to this? The water that is dripping is cold. I thought that if it is shut off in the house or from the main line, the water should not be dripping. Someone please help!

Call the plumber back. It's his problem.

Just turning off the water doesn't do anything until all the water in the pipe drips out. That will take a long time. By turning off the water you trapped a small volume of water in the pipes at 45 PSI.

You need to relieve the pressure and drain the water level below the area that's dripping in order to make the drip stop.

Is it dripping above (spout) or below the sink (at the shutoff valve)? A fitting or around the stem?

Where does it drip from? The stem? The 1/2" or 1/4" compression nut on the angle stop? Or does it not shut off completely?

When you close the house shut off the system will still have pressure in the lines until you open up a faucet and bleed the pressure off. Just shutting off the house doesn't relieve the pressure so the leak would keep on dripping until the pressure bleeds off. Regards, Tom

It was dripping from the spout and now it is a constant flow. I shut it off last night @ the shut off valve under the sink and sat a bucket in the sink to see how much water was coming off and the bucket was full this morning. I also removed the faucet itself last night and the water was still coming up.

Sounds like the washer in the angle stop needs to be replaced. If you can't locate a washer to fit then simply replace the angle stop. Use the old compression nuts and ferrules if you do. Good luck, Tom

Ok, I am not familiar with the angle stop. Where is it? Thank you

Sorry, but I think I know what it is and he put a new shut off valve on yesterday.

Angle stop=shut off valve. Are you saying the new shut off valve's the one that's leaking?

No, it is leaking from the faucet spout.

Ok, I turned the shut off valve off under the sink & unhooked the water supply line that leads to the faucet. The water was truly not coming up until called but the supply line continued to drip the water from the line. Does that just means it is calling up too much water or not draining properly? I hooked everything back up and turned the water back on under the sink. It is just a drip now.
