I have an issue with a very slow leak coming out of the house's main water shut-off. Water very slowly leaks, mostly when the water is turned off or on, from the stem and the compression nut as shown in the picture. I believe the rubber washer or o-ring that is under the compression nut needs to be replaced.
I've tried tightening the compression nut, but when I get it too tight then I can't unscrew/screw the valve open and closed.
I had the city out to shut off the water at the curb so I could take this apart and replace the rubber piece, but they can't get the curb shut-off closed. I don't have enough pipe to have someone freeze it.
Is this possible to fix without shutting the water off? Can I screw the valve closed and remove the compression nut and replace the rubber piece?
I'm sure this leak has been going on for a long time and I can just tighten/loosen the compression nut when I need to turn the water on/off, but I'd like to fix it correctly if possible.
