I recently purchased a new faucet for my kichen (single spout, dual knob). I don't remember the brand... got it at Lowe's, and when I run hot water, the spout that typically swivels side to side, tightens up so tight that I can barely move it. I get it to move freely again by running cold water through it for about 35 seconds. I'm afraid my wife is going to break it by forcing it when it is seized up. Need help fast.

Going to need a brand name here. Many "poor" quality fuacets have orings that actually "swell" with hot water causing problems such as you describe. I have even seen it with high quality brands. The difference is the warranty between the brands and ease of repair. What is your hot water temp? If the water is to hot, you may have problems with almost any faucet. Your water temp should be no higher than 125 degrees.
