shut off valve under sink
My faucet is cracked so I need to replace it. I went underneath to shut off the water supply and water sprayed all over. How can I fix this leak on the shut off valve so that I can fix my faucet? Also, I am really a novice with plumbing (although I have replace my kitchen faucet, toilet fill valve (I think that is what it is called, it was a Fluidmaster I put in), and I have attached a kitchen sprayer to my toilet), is this leak something I can handle?? Please say it is, we don't have the moolah for a plumber.

yes and no
I will definitely fix this myself if I am at your situation:

this is what happened I believe, the switch is kind of broken, which is very common, well, contributed by the fact that it wasn't being used for years, and once turned, things start to break, and don't know if there is anything to do with the quality of the switch, don't get me wrong, but most builder/people go for the cheapest type when the first install.... but nevertheless, this is a common thing happen arround....

so to fix it, you need to shut down the main supply, then release the water in the pipe, then replace the switch... if you don't like soidering, you can use the compressed type... it is easy to install..

then turn back on the main switch, then turn on the water switch slowly because you are talking about big pressure trying to run into the pipe....

then you are all set.... may want to change everything you want to change at one shot, but doesn't have to be....

Under the handle on the valve, there should be a nut. This is called a packing nut. Turn it 1/4 turn and try closing the valve again. Since these valves don't get operated much, the packing is loose and turning the nut will tighten it up.

Thanks alot for the responses. I will check out the packing nut, hopefully that is the problem. I was able to fix the faucet without shutting off the water, thankfully, but I still need to resolve this issue, so I thank you for the help.

Sorry I didn't mention it in my first answer but the packing is what prevents water from leaking out around the stem. Without use, the packing can shrink and this will allow leaks when the valve is operated. When you snug the nut, the packing is, once again, firmed up against the stem, preventing leakage.

Thanks so much for the explanation!

Good advice Majak. One small tip, when you tighten the packing nut, go ahead and turn the handle just a little clockwise (like you wanted to close it, but just 1/8 of a turn or less). That makes it a little easier to be sure the valve isn't stuck the next time you need to use it. Occasionally when you tighten a packing nut with the valve all the way open or shut it will tend to make the stem stick. This is probably more perception than reality but it's pretty simple to just leave it a tiny bit closed.

Thanks MajakDragon, that took care of mine. Now just to make an outlook reminder to tighten and loosen them twice a year to prevent them from locking again.
