If your pipes bang when you turn on the water, and all the pipes are anchored correctly, you should add some straps or cushion the pipes with a rubber blanket. There may be times when you will need to do both. Make sure that if you have copper pipes, you are not using galvanized straps. If a pipe ever freezes, you need to make sure to shut off the water. This will keep the pipe from bursting and causing you major damage to your home.
