Pioneer2AM401-BN Americana Two Handle Kitchen Faucet PVD Brushed Nickel

This faucet looks great in my old house. But I have been using it regularly for a month and there are two issues that have arisen. 1) the central stack has become loose. It tightens up when water pressure is applied by running the faucet. When the water is not running touching the faucet to turn the spigot for example reveals that the joints between the sections are loose and makes it feel like it is poorly constructed or perhaps defective. If there is a way to retighten the stack this faucet could earn back one star. 2) sprayer unit works fine when in use and it does seems to not get too hot when spraying hot water which is a problem with other metal sprayers that I've used. The problem is that when the sprayer has not been used for a while and one turns on the faucet the sprayer unit will dribble a bit. Sometimes it will continue to dribble water until one uses the sprayer and then when one stops using the sprayer the dribbling will stop. The dribbling resulted in water running down the hose and dripping onto my brand new cabinet floors under the sink leaving a water damage mark. I now have a container down there to capture the overflow while I decide if I need to replace this faucet due this problem. If this problem could be fixed then the faucet could earn back the fifth star.
