I cannot shut water off.
 

My sink in my downstairs bath had a drip for awhile. It has been getting bigger and bigger to the point it is a flow.
I have turned the knobs far over and even attempted to shut off water by turning the shutoffs below the sink and it will not quit untill I cutoff the main.

So I cut off the main and undid some of the rings to attemp to take off the cold water shutoff and replace it, but then some water started to flow out as I was disconnecting it from the main. It may just have been some small backup but I was hesitant to pull it all off.

Does this sound like a faulty shut off valve to you?

Thank you in advance for the help.

The water that you see after you shut off the main is probably residual pressure. After you shut off the main, open up a faucet on the bottom floor to relieve the pressure, then use a small bucket under the sink to catch any water left in that line so you can replace or fix the shut off under the sink.

Sounds good.

Does it sound like a shutoff problem?

I would think that if it had something to do with the actual faucet, then I would still be able to use the shutoff.

After you shut down the main, you need to either replace the washers in the faucet and the cold water shutoff or replace them both.

I could be a combination of both the faucet and the shutoff, it's common for both to have problems.

Lame.

But thank you.

If your faucet washer/seat fails its not unusual for the cutoff under the sink to be marginal when you use it. Most of these sit untouched for years in one position. Its not a bad idea to cycle them once or twice a year just for giggles. I would cut off the main and replace both at one time.

If your faucet is leaking... then obviously the faucet is bad.
if you close the local shutoff and the faucet continues to leak, the shutoff is bad as well.
it's not lame, just common sense...

Is that a 1960's word? :laughing:

I just meant the situation is lame.
Actually the word was used widely in the 90's.
and it was a stupid word back then too :)

but thank you all for the help. I am going out to purchase 2 new shutoff's and a new faucet.

wow man....this thread is far out man.....

It may be redundant, but I have shut-offs between the main shut-off and service valves on most of my plumbing. If there's ever a problem, I can shut the one room/appliance off without shutting down the whole house.

Yes assuming those valves control what you want to shut off and they hold.
