## Customer Reviews

### ⭐⭐⭐⭐⭐ Drip System anti-siphon in-line valves.
*by M***D on May 29, 2025*

These work extremely well. I use them to prevent water siphoning out of bird baths and fountains.

### ⭐⭐⭐⭐⭐ These seem to be working fine to me
*by J***N on August 28, 2024*

I tried hooking one of these up backwards and my flow stopped. Hooking it in the correct way the water seems to flow the same as before. I call this a success. If it lasts over a year then great! If not then well that's what I get for buying cheap.I may re-review if I notice they stop working at some point.Side note:Not sure why people think they can supply enough pressure with wee little human lungs. Obviously the psi in a water hose is going to be higher than a set of lungs can push.If someone tries to say they cant blow through it and gives a bad review, ignore it and keep scrolling. If you're not supplying measurable data and saying its crap then do us all a favor and stay out of the reviews. Thanks.

### ⭐⭐⭐⭐⭐ Perfect
*by S***R on April 12, 2025*

Works perfectly!
