The vertical distance between a washer’s drain outlet and the standpipe or laundry tub the place the hose discharges wastewater is a essential dimension for correct equipment perform. For example, a typical home washer may require the tip of the drain hose to be positioned between 30 and 48 inches above the ground.
Right vertical positioning prevents siphoning, the place water is constantly pulled out of the washer drum throughout operation. It additionally guards towards backflow, which might introduce contaminated water again into the equipment. Traditionally, managing this dimension concerned cautious placement and securing of the drain hose. Fashionable washers typically incorporate options like anti-siphon loops or inner pumps to mitigate a few of these challenges, however understanding the underlying physics stays important for correct set up and troubleshooting.
