are your overflows pipes glued in your overflow box?? iff not just remove the primary and the emergency and make it so the primary goes up just past half way and make your emergency about 2 " below your overflow box teeth that ways you can use your gateevalve to keep the water line high and thus no sound of water entering the overflow box.if they are glued then i would condider draing the overflow box and adding new pipes using unions or couplings
