Christ, reading the thread you would think OP is playing with Gas or High Voltage power. The man is trying to get water from one side of a room to the other, with gravity & a pump on his side. This isn't rocket science, just some clever thinking & calculated risk.
Some of you guys come across as real pretentious self riotous assholes, it has to be said.
OP - Jerry rig up a trial of it. Buy the pipe, duct tap the outlet hose of washing machine into pipe, run a few test cycles & see what happens. If you poor water all over the floor & flood the neighbours it's your own fault, but let us know how you get on?
edit: Considered rigging up some sort of holding vessel that can drain slower? Hang one of these behind/next to the machine? Heck, you could use a garden hose to drain it slowly over a long period of time if you are only using the machine once a week.....
