You said you had a cleanout on the first floor that was backed up with water.. i would auger the drain from this cleanout. Once you have the drain cleard, have a plumber come out to send a camera down the drain that was plugged to see if there is a problem in the pipe(roots, broken pipe, etc.). Lee.
