Hello,

I moved into my house in February 2009. The people who had it before
me only bought it to fix it up. They purchased it in August 2008.
During that timeframe they install new faucets everywhere in the
house, including in 3 bathrooms. They used the same model of faucet
in all 3 bathrooms.

In one of those bathrooms I started having problems with the faucet
back in May or so. It started to drip and as the weeks went by it
dripped more. I turned the cold water valve to OFF. It still dripped.
There was no hot water valve under the sink and I didn't know which
valve in the basement was the correct one so I couldn't test that one.

I eventually took apart the cold water handle to check the inside of
the faucet. Everything looked fine to me (I'm no plumber though). But
I didn't expect anything out of the ordinary because it is less than a
year old. I put the cold water side back together and turned the valve
back on underneath the sink. It turns out that I ended up making it
worse because I had a steady stream of water coming out of the faucet
without even turning either the hot or cold knob to the open position.
So at that point I just turned the cold water valve to off and went
without cold water. It would still drip but it wasn't as bad and it
wasn't increasing in frequency.

This past weekend my parents came over and looked at it. We found the
water valve in the basement for the hot water for that faucet. We
turned it off and did the same thing as I had already done to the
cold water valve for the faucet. We didn't find anything wrong
(didn't expect to because it is new) and put it all back together.
Now the faucet drips more than it did before (but not a steady
stream) and I can hear it now as the water falls down the drain. It
is very annoying. And I don't think it can be an issue of water
pressure destroying the valves or anything like that because the
other faucets are not having trouble.
What could cause both the hot and cold water valve in the faucet to be
bad already when it is less than a year old? Is the main spout at
fault? Is the only remedy to replace it? The American Standard
website says the faucet is exclusive to Home Depot. I didn't buy it
but I should still be able to get a replacement through the lifetime
warranty, correct?

That's weird. Taking something apart and putting it back together usually
fixes whatever's wrong - at least that's been my experience.

I once did that to a clock that was running WAY fast and was never right.
Afterwards it was right twice a day.
