My washing machine hose connects to an extended hose, which is turn is connected to the waste under the sink. From what I can gather, retail shops will only connect directly into a waste pipe, so won't connect a new machine. Being a lone female, will be be fairly easy to undo the travel bolts, level up machine (I can slightly lift my present one) and connect the washing machine hose to the extending one? Do I need to buy any kind a adapter/connection for the hoses?
