I am in the process of converting a bedroom into a master bath. I ran the hot water lines from an existing shower next to the bathroom, ran the lines up through the floor and capped the lines. It was like this for 2 weeks with no issues. Yesterday, I cut the caps off the lines and connected the water lines to the tub fixture. Now the hot water volume in the existing shower is low. There are no leaks in the line that I can find. Any idea what has happened?

I am in the process of trying to find a plumber to hook up a drain for the washer in a condo. I keep getting differing opinions of what I need to do. (A) I was told that I could hook up the drain to the sink drain. (B)I was also told that it could not be done to the sink, that I would have to feed into the main drain in the ground (through concrete) Also the washer is located on a different wall from the sink, does it sound correct to say the pipe can fit through inside the wall??? Im concerned the studs would have to be cut and then re-enforced...cabinets will hang from that wall. Please help
