Turn off the main water supply but water is still flowing in the house


Valve is probably worn out or will not seal because of mineral buildup.
Common problem as the vales are often not used for years. Solution is
usually to have the town come out and turn the water off at the street.
replace main valve.



Yep.

Or if you call a plumber they can turn it off at the street as well.



One thing to try though would be to open it up and try again.
Had a friend one time lightly tap the valve with one of those rubber
hammers. He did it twice and the second time it worked. His theory was
that he dislodged whatever was causing the problem. Mine was that it was
5-6 time he had moved the valve back and forth and that is broke it up
enough.
Anyway.. one of those things that might work and there appears to
be no good reason not to try it.
