What exactly is an airtrap? #2-What is the purpose of the ball and is there any distinct sound when there is a problem within the housing where the ball is located?

Steve for Model Number 110.49972602

ANSWER Hello Steve, The airtrap actually prevents any suds from getting into the pressure switch. It is an area where, if suds get into it, the suds will have to pop instead of interfering with the pressure switch operation. The ball is located in the outer-tub-to-pump hose. The purpose of the ball is to keep foreign objects and debris from getting into the pump impeller. It makes no noise but if there is an issue in the drain hose, the unit will not drain.
