Product review (5 stars): Replacement Drain Spud
After cleaning the drain hose, I reattached it to our Aprilaire humidifier and tighetned the hose clamp.  Opps... Overtightened it and broke the drain spud.  Found a very reasonable price (with shipping) through Amazon.  Ordered and received the replacement part very promptly.  Perfect match for the original part I was replacing.  Problem solved.  Much more careful now tightening the hose clamp.  Thanks!
