Hey James......I tried forcing water backwards, using a hose, but I'm not sure that I did anything. I saw water flowing out of the suction hose, but I doubt that I was able to achieve any kind of real pressure to dislodge something. I will take it apart, and look again. I don't want to remove to much of the motor assembly, because I picture that it's easy to take apart, but, as usual, putting it back together is not ever the same. How far into the motor assemble do I remove?
