I have a leaking faucet in my tub. Do I have to turn the water off to the house before I attempt to fix it. I did not know if the pressure in the line would make a bigger leak. Next, what would be the cause of the leak. We have water that has alot of lime, and I do not know if the faucet has a washer or if I just need to remove the lime build-up like I do from my shower head. I have already taken it apart, as far as I could, but now I have the last part of the nozzle on the pipe and do not know how to remove it or if I need to remove it. Anyone with any advice?????
