Product review (5 stars): Fixes the "common" issue of the agitator running when the unit is filling up...
It fixed the issue with my agitator going on as soon as I turned on my maytag centennial washer.  Finding the part number was the hardest part.  A youtube video explained how to pop the top off with a putty knife.  I cut off about an inch of hose, blew in it, stuck the hose on this part, snapped it in place, and I was back in business.

I just wish Maytag/Whirlpool would realize this chronic problem is a manufacturer's defect (in my opinion), and offer to replace these for free (or at cost), but that's just not how companies treat their customers any more...  My original part lasted about 6 years.  I just hope this doesn't keep happening.
