Report "2 years ago. I think it is a Melrose model. The midde "barrel" is mounted directly to the sink (i.e., it doesn't have that plate that mounts to the sink -- if that makes any sense). Lately, the "barrel" is tightening up to the point where the faucet won't swivel between the two sinks. Soon the faucet will be stuck pointing over one side of the sink. Any ideas on how to loosen it up or fix it?"
