To prevent a disaster if an washer overflows or a leak occurs, install a recessed washer box in the wall directly behind the washing machine. Choose a box with the single-lever shut-off valves included, and mount the box for easy access. This recessed box provides connections with shut-off valves for the water supply hoses and a drain for the washer's discharge hose.
Install a washer diaper pan under your washing machine. Set the tray so it has a direct line that pumps into a laundry sink drain or floor drain. If the machine leaks, the water will be drained away.
