I recently bought a house that has something strange (to me). The washing machine drains into a slop sink (there is a steel lint filter at end of the hose), under which is a big rubbermaid storage container that contains a sump pump, and this ejects into what I think is the sewer line. Trouble is, the container never drains completely, leaving at least 1/4 inch of black sludge on the bottom. Also the entire pump and container is covered with this sludge. If the container doesn't fill high enough after a washing load, the float won't activate and the water stands, causing a nasty smell. Even when emptied, half of the basement wreaks.
It is a real hassle manually pulling up the float up to empty the container (not to mention messy, my wife will never do it), or unplugging the float and directly plugging in the pump for a minute to drai nthe container after using of the washing machine.
anyone have experience with this? My neighbor mentioned that everyone was required to install like this many years ago, when the city built a second sewer exclusively for rain water (no graywater allowed, apparently). Unfortunately neither of my closet neighbors would let me see their setup, so maybe they aren't in compliance (they were a bit dodgey when I asked to see it).
I've tried dumping bleach in there, also took it all apart and sprayed it clean with a garden hose, but it doesn't take long for the smelly sludge to return.
Any advice appreciated.
