whoever suggested the leaf blower, many thanks!! i just got a 2 3/4" rubber ball my grandson dropped into our 3" outdoor drain! tried everything without success. was going to rent a snake, then filled the pipes, leaf blower fit perfectly into the drain pipe, water, debris and the ball all came shooting out of the end. yay, saved by butt!!
