We have had several Delta faucets in the past and have been very happy with them, so when the plumber replace our kitchen faucet with Delta DST-400 two years ago, we thought we were all set.

Last week we started having a problem turning the faucet completely off. Now we have to shift the handle around until we find just the right spot or the faucet continues to run. 

I have to say that I am quite disappointed that we are having this problem after only two years.
