My questions a

o Why does this valve start dripping so soon?

Something is worn out, like a washer or seal. Not so soon, really


o How can I prevent the new valve from failing so soon if I replace
the old one with a new one?

Don't ever use it.


One thing I need to point out is that the valve is in the basement,
and the water pipes come from the ceiling of the basement, and reach
the valve that is mounted in the middle of the basement wall. I am
wondering whether there is something in the water that may have sunk
down to the bottom of the water pipe and touched the valve and might
have corroded the valve or scratched the valve.

Could be rust or sediment in the water that wears it over time. My facet
seals used to wear out quickly all the time until I installed a filter.
