I have dumped it out, removed the rod, scraped the insides to get that accumulation of I don't know what the clay colored dirt mess that coats the sides. reassembled and it still leaks. Is there any way to get it back to Clean, short of a large round wire bursh in a electric drill? I am just about ready to ream it out with a huge ball of steel wool. If not I can plug it and go to the hand dipper but I seem to get a better fill with a good stream. Thanks in advance. JB
