Less than a year ago I originally replaced this same item on my new Hot Tub pump. This year the barb simply sheared off from the pump and lost most my water. Lucky for me I was home and noticed the loss of water. This year it was much more difficult to replace since the pump wasn't sitting on my work table but under the fixed one-piece formed body of my Dream Maker Hot Tub. Not sure why it simply failed after one year of operation. Hopefully it was just a fluke and a probable foreign manufacturing. Defect. Bought TWO this year just in case I needed to replace another, yet again, sometime in the future. I'm betting failure was a fluke incident. I hope.
