Drain Hose For A MT DC Washer
Corrugated plastic will work just fine if it is large enough, it needs around a 1" inside diameter for the entire length.
MT switched to corrugated plastic hoses on these washers the last few years they built them with no ill effects.
You do not want a rubber hose like the ones Launderess said were posted on Ebay, that type of hose will kink and restrict water flow if you just look at it.
