From your description, my first guess would be that you did not install vertical air cushions on your new wate lines???? Now, you have increased water flow/pressue and when the water starts to flow or shuts off, you are hearing the "water hammer" when the flow stops. An air cushion is necessary to provide a "shock absorber" to dampen out the quick flow change.
