Hi, hope you can give some general info before I call a plumber – dreading that one I can tell you!
(General background: I have a property which is ex-council on 8th floor that I rent out. Property empty right now and I’m doing appliance test).
When running the washing machine, as it empties, the water backs up into the sink – quite a lot. The machine is situated directly next to the sink, so water doesn’t have far to ‘travel’.
Do you think a pipe/drain blockage is the problem?
