Leaks
I bought this from Lowes about 6 weeks ago. I just found a puddle of water under the sink. The faucet is leaking between the handles and running down the stopper handle in the middle. Both the hot and the cold sides are doing this. Delta used to be a great reliable brand, must be made in China like everything else now days.
