if you really can't solve the problem
but still want a top-loader, there is a simple solution. Get a sink which has the same or greater capacity as the washer. Hook the sink to your drains (don't forget some sort of easily cleaned trap. Lint is lint is lint.) Hook the washer up to drain directly into the sink. Of course the sink will fill quite rapidly, but will also, itself, drain at the rate your system can tolerate.
This way you can have your cake and eat it, too.
