My sink was dripping so i decided to fix it.
I shut the water off to the house at the street. no water comes out when i turn any other faucet on, yet somehow, my bathroom sink is still dripping!
How is water coming out of the bathroom sink still, when the water is shut off?

Unscrew the aerator it could be partially plugged not letting the neck drain.

It is only a one story home.
the water is now coming out of where you turn the cold water valve under the sink.
but how is water still coming out?
the water has been turned off to the house for hours

possible answer: valve is not 100% closed due to operator error or a bad valve (not uncommon)
I open other faucets for a bit to drain down the system. Then I close them, except where I'm working.
This pretty much air locks the line and usually stops the dripping

Do you have a 2-story house?

And....you might try closing the valve to your water heater.

You could be siphoning water from it.....especially if you have some other faucets open.
It should quit after 40-50 gallons if the dip tube is full length.:laughing:

I prefer shutting the water heater off and draining it.

This shows the importance of turning off the water heater heat even if you are not explicitly draining the water heater tank.

An all electric water heater can self destruct if it kicks on and less than a quarter of the tank has emptied out.

However the most likely cause is the shutoff valve you closed being leaky.
