Pipes knock ALL DAY after toilet runs!!!!
Bought a Brand new house by Choice Homes 3 years ago; they used a bootleg plumber. Water temp never right; does not get hot. Called them several times; told that it was correct. Later, pipe burst in wall when house was less than 2 years old. They tried to deny that it was under warranty. Finally got them out, and they fixed it, but tore up wall and repair work looks shoddy. Now, a year later, I hear pipes knocking in my wall ALL day long, as if they are threatening to burst, after the toilet runs. Toilet runs, then pipes knock loudly. Toilet started running louder a couple of months ago, then the pipes started knocking loudly. PLEASE HELP!
