If your outside drain overflows only when several appliances run at the same time, the drainage system is struggling with the combined volume of wastewater. Washing machines, dishwashers, showers, baths, and kitchen sinks can all feed into connected pipework. One appliance may not create enough flow to expose a problem, but several running together can overwhelm a partially restricted drain.

If your kitchen sink backs up when the washing machine drains, the problem is usually not the sink itself. In most cases, it means the shared waste pipe cannot move water away quickly enough. A washing machine pumps out a large volume of wastewater in a short burst. If there is any restriction in the pipework, that surge of water will look for the easiest place to go.
