Adopted Yorkie Pees in the House?

I adopted/rescued a 7yr. Yorkie. The original owners stated he was house broken/trained. It has only been a week, but he keeps peeing in the house (kitchen). I have put up gates between the kitchen and living room to limit the peeing in one area. Take him out several times in the am before work (same time) when I get home and in the evening, within about 20 minutes of being in the house, there is a little puddle in the kitchen.

I clean up the pee and even spray the area that he has touched. He normally will not go back to that part of the kitchen. I have put down pee pads and he just looks at them and doesn't use them. He will go everywhere else except on them.

I have limited his water, as he will drink the entire bowl up if you let him in one sitting. I caught him once starting to pee and raised my voice and took him outside right away. I have praised him when he pees outside. I am not sure what is happening. He is very loving and wants to be with us, but I am worried that he will pee in the other parts of the house. I am not sure what it might be. I just purchased a crate and will overnight him in the crate to see what happens. I am not sure what other things to do or what might be happening that he pees.

Any advise?
