## Customer Reviews

### ⭐⭐⭐⭐⭐ So much better than plastic floats
*by J***F on September 7, 2025*

Works great. All my plastic floats failed and leaked

### ⭐⭐⭐⭐⭐ Works great, don't bother with included adapter
*by P***E on April 5, 2025*

Wish I had installed this ages ago! I used this to auto fill my chicken waterer. No issues. Installing was quick and easy. I ended up getting a 1/2" npt to 3/4" garden hose adapter to attach to it. Maybe that is why I didn't have the leaking issue people seemed to have in other reviews. The included 3/4" to 1/2" adapter is npt and not garden hose thread. Even when using it just to get 3/4” npt, it is super loose. You would need tons of thread tape and there is nothing to stop it when you screw it down. It just keeps screwing down the elbow beyond the threads. I wouldn't bother with the included adapter. Another review said that it fills very slowly. I did not find that to be the case. It actually startled me when I turned the water on. It sounds like the hose on full blast on the jet setting. Once the water reaches the valve, it shuts off. So far so good, will update this review if needed.

### ⭐ Chinese piece of garbage!
*by J***N on August 1, 2024*

The elbow fitting can't be tightened enough to keep it from leaking. If this valve constantly leaks, I could save the expense and just leave a hose in the tank on a trickle. I used teflon tape AND puddy. I tightened the fittings until I was afraid I'd break the valve. It still leaks! JUNK! The gaskets they provide have don't fit anywhere in the assembly. But if they did fit, the would have nothing to seat on. Waster of money and time!!
