I am assuming that you are currently hooked up to City Water. I am also assuming that if your Park Model is equipped with a fresh water holding tank that you have checked to make sure that your water pump is shut off.
The noise you are hearing could be from excessive water pressure coming from the city water system you are connected to. Your particular model trailer does not come with a built-in City Water Pressure Regulator. If you have not installed one already, you might want to install one now.
