Even though it is made in Italy, it still has a plastic float inside. For this price, I expected all brass and copper construction. My original Taco Hy-Vent started leaking water, so I replaced it. The new one is slightly different, with the exhaust port moved off-center on the top cap. So far, it works well, no rust or leaks, and my radiator baseboards are quieter.

Does exactly what it’s supposed to do.

I purchased this to replace an old HiVent covered in residue, and the vent cap would stick. This was a perfect fit and solved the problem of the old valve not venting properly. I hope I don't need to replace it again soon, but I'd buy it again if I had to!

The valve I’m replacing is the same make and model, but it only lasted two years before leaking from the bonnet. This type of valve should last longer, which is why I gave it three stars. The valve works as expected, but I expected more longevity.

My hy vent and my circulating pump went out on my boiler just as a storm was to arrive. I live in a rural area 3 hours from the city. Vent and pump went out on a Friday. 6-hour round trip to the city and no where to buy the hy vent or pump. It saves the day. Parts arrived 2 days later. Free shipping!!!!! Saved huge in time and fuel. Thank you

The product is Taco air vents for a hydronic heating system. They were as expected and installed easily, to replace four older ones (one of which had developed a leak).
