Yes it does happen all too often. Should it? No! Water back-pressure is pushing through your water pump a filling your fresh water holding tank! I fixed mine by purchasing a "sharkbite" check valve and placing it in the water line between the freshwater holding tank and the water pump. Problem solved. Obviously make sure you install it with the water flowing the proper direction... have the arrow on the sharkbite coming from the fresh water tank, pointing towards the water pump.
