Add no more than roughly four feet of extra hose. Break these rules and the washer siphons, drains slowly, or leaves standing water.<\/span>\r\n\r\nThe rules below show how to extend a drain hose correctly, why the limits exist, and which parts to use.<\/span>\r\n

Can you extend a washing machine drain hose?<\/span><\/h2>\r\n[lwptoc numeration=\"none\"]\r\n\r\nYes, when the washer sits too far from the drain or the hose will not reach the standpipe. Manufacturers make dedicated extension and coupling kits for exactly this situation. The key is that \"extend\" does not mean \"as long and as high as you want.\" The pump can only push water so high, and the drain has to keep an air gap, so you extend within the manufacturer's limits, not past them.<\/span>\r\n

What are the rules for extending a drain hose?<\/span><\/h2>\r\nStay inside the height and insertion limits. Whirlpool's washer service and installation literature spells these out (always confirm the exact figures in your model's installation manual, since they can vary by machine):<\/span>\r\n
