Then turn on the black tank flush, it will "push the bobber around in the tank" and hopefully, the water currents will push the bobber into the brush. If you're "sort of lucky" a "round, red/white ball bobber" will roll around in the black tank, dragging the hook behind it and hopefully snag the brush head.

You may spend a couple hours "fishing", but this time of year, most places, boats won't float in the water and it's too cold to sit "out on the ice" so, might as well take up a new hobby, "toilet fishing in the comfort of your own RV".....

But what if he hits a snag?
