I found that they grow in the slime that coats the drain trap. I reamed it with a stiff brush and applied some draino. Seems to have stopped the problem for now.
They are back and faster than before. I need a bushing tool that can reach into the piping for at least 15 feet and turn 90 degrees. Any help would be appreciated. Thanks
