## Customer Reviews

### ⭐⭐⭐⭐⭐ Exactly what I needed
*by J***S on April 26, 2020*

Whenever you install an electric water heater that is on the 2nd floor of a building you have to install one of these to prevent siphoning. Of course the local store wanted over $50 one of these. Good thing I can just order it off Amazon for a 1/3 of the price.

### ⭐⭐⭐⭐⭐ My inspector was perplexed
*by J***D on June 15, 2020*

He didn't know why I had installed it, since it isn't required by code in Oregon. But after I told him that I wouldn't have to open faucets to drain the tank, he figured it was brilliant!A quicker way to flush the tank.No leaks, works as expected.

### ⭐⭐⭐⭐⭐ Works as it should
*by D***R on August 6, 2019*

Put this on our stills to prevent vacuum and they work. When still cools down they pull a vacuum so these prevent "sucking in" of the still. (We are legal!)
