draining washing machine upward

I am looking into putting a washing machine in my basement. The problem is the washer would need to drain vertically (straight-up) 8 feet then horizontally (above the cieling) another 15 feet to the main drain. Can a washing machine push water 8 feet up? And is are there any issues with doing this (vent pipes, backflow, ect...)?

Thanks for the help.

You would have to contact the washer manufacturer about doing that. I personally do not think it would be a good idea.
Yes, it would have to have a vent and a trap and a backflow perventer. You would also (probably) be replacing the pump in the washer because of undue strain.
Is there no floor drain in your basement?
You could also build a sump and pump the water from that to your plumbing. Good luck.

It can be done. Grandma did it for many years, but I don't know if it was safe... I would probably drain the washer into a tub and use a sump pump to pump the tub to the drain. Grandma's drain hose went right up the wall to a pipe in the ceiling. You might want to call a plumber in on this one to make sure you stay in code.
