I appreciate the suggestion, and they did suggestion I check it periodically - pour a gallon of water down it. The causes you suggest could happen and result in a. 100^ blockage in 24 hours. So doing it every 6 months is not enough. In fact, he suggested we pour a gallon down the drain every month. So, we put it on our schedule - about 2 1/2 minutes total. I can do that too.
