1/2 Inch Brass Valve with Plastic Float Water Float Valve with Adjustable Arm Automatic Fill Float Ball Valve for Water Tank Fountains Livestock Waterer

Works perfectly keeping my fish pond full.

It works as advertised

Difficult to find anything not to like about this product. I was never happy with the original installation for the fountain in our garden, first the plastic hose burst from the water pressure (needing a pressure regulator installed in the supply line) then the plastic float valve broke causing our front yard to flood. So, having more trust in metal I installed this metal float valve with all brass fittings and a braided hose. One minor detail is the brass elbows to avoid any kinks in the hose so it's rather a no expense spared project after the problematic history of flooding the yard. One comment I should make about the thread on the valve after reading reviews about the threads being an issue. the thread on the valve is in fact a 1/2" IPS (aka FIP) which is commonly used on toilets and hoses like this that fit it are commonly available in just about any hardware store. It isn't a tapered thread, and it isn't supposed to be. All told, I'm very happy with the result.

After trying many different brands this one wins hands down! Although our pond pump came with a float-fill device it did not work properly. During hot summer days we were always topping up our pond by hand. This one works perfectly. The fitting is made of quality brass and the float of durable plastic. So pleased with this product!

After I had a little more time to go through my installation and then I removed it and it was like the 5th time, I was surprised that I have been over it so close yet I have missed the leaking float. It's actually got a pinhole in one end right along the center line from the mold, and it was dripping constantly upon removal and I think it is actually leaking in multiple spots along the center line all the way around. You can actually see inside the thing on the pinhole. What a bunch of garbage. I see it isn't like it's the first one, I think I have come across a few others just in recent reviews. I have a replacement for this one coming but I don't plan on using it, I will be returning both. It's officially been a giant waste of my time and I'm sure not pleased that the things don't receive any quality control before sending out. I bet there are a lot more where that came from. Seems like the float is most likely too small for it to create the lift pressure to shut down. Doesn't matter if you have the water set to a trickle or any amount of flow, that float is just not getting any pressure on the valve. It will run all day and night and I was shocked to see my flood when I got to in the next morning. Adjustment of the float makes no difference at all, and it will completely submerge and it is still allowing a little flow. I can get it to close by lifting up with my finger and it is not the valve itself because it shuts down just fine. I have read about leaking floats on this one but it's not getting any water inside the float on this one. I believe it's just too small. Not sure if anyone has had the same issue, and sadly compared to the other ones that you see the majority of the sellers have being plastic, I really don't want to say that the quality is terrible, but I believe it is a poor design of the float, and I have questions about the shape, it's wedge shape seems to be a waste of design and it will submerge the narrow end of the wedge and the float doesn't even begin to lift or float until it's all the way to the other end, the larger end before you can see it begins to float and create any lift at all. I think I'm going to have to go local and find a replacement for the float or make something to get by for the time being.
