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?

thanks for any suggestions

Maybe sand or other debris under the valve/cartridges and it will not
seat properly? Did you check that the valves are seated *tight*?

Cartridges go bad, how long I don't know.
