Product review (3 stars): Very fat 1.5" inch hose
This hose is a giant.  It's about 1-1/2 inches fat and it's exactly like a shop-vac hose.  Attaching it to the washing machine was no problem.  Inserting it into my home's drain pipe was tricky, though.  Notice in the product picture that there's only a short smooth section on the end before it becomes corrugated.  That part is only about 3/4" long, and that's all that would fit into my pipe.  I had to Really secure it very well to the wall so it wouldn't pop out of the pipe.  (My house has a 1-1/2" pvc drain pipe.  If yours is 2" you should be ok).  I did like the 6 ft length. It didn't leak like my old one did.
