Recently bought a ranch with a finished basement. In the basement, there is a full bath and washer hookup. Recently when my washer was discharging water the water came up through the drain. Plumber stated that the washer discharges more water than the drain can handle. Now the issue, my son was taking a shower upstairs when my wife came in and flushed the toilet. The downstairs bathroom toilet water jumped and splashed. Then specks (sewage?) Came up through the downstairs shower. I feel I have a major plumbing issue. FYI- the plumbing was advertised as 80 percent new. Any ideas? Thanks

You have a blockage somewhere between the floor drain and the connector to the city sewer. Have the plumber (maybe another one) auger the line, there should be a cleanout as the main line exits the house and hopefully, one outside too.. The interior plumbing may be 80% but people almost never replace the main outside sewer line unless it breaks or deteriorates. Hopefully, that is not your issue, could be roots. If the auger brings up a lot of dirt and soil, you may have a broken pipe.

Need a little more info. Are you on a septic tank,treatment plant,or city sewer, check the vents to be sure they are through the roof or stopped in the attic?If septic or treatment plant, how deep is it buried and is your washing machine ran separately (bypassing the tank) or tied in to the tank sounds like two separate issues.
