Using these to vent my pool heating system and they are doing a great job so far. Been in for a month and are working, system is fairly low pressure and these remove the trapped air well. They do allow the air back in when the pump is off as they don’t have check valve feature. I didn’t add a check here as I was afraid it would hurt the air removal with my low system static pressure (

We bought a house with a hot-water circulating pump in a high loop with no way to purge. It air locked and began to cavitate. I added a tee above it with a ball valve and topped it off with this float valve. The float valve works fine and doesn't spit water when the air is gone like many I've seen in the past. My only problem is with the male threaded portion which is either too short or not quite tapered enough. It leaks a tiny bit at the thread and may stop at some point, but I just keep the ball valve which I installed below it in the closed position for the most part and only open it to purge every few weeks. It's doing the job and for a reasonable price.

The price was great and they did just what I needed. Once your application is up to pressure though the air may not be released since I think the back pressure keeps the float valve closed. For this reason I slowly added pressure to allow the air time to release.

The unit comes with an o-ring installed and a gasket with adapter. Not a single unit as pictured. There are no installation instructions included and the o-ring had a cut in it. I tried thread tape and thread sealant and it still leaks. Pay a little more and buy a Watts. It does however function as intended, venting the air from the water line.

Good quality. I like the adapter it comes with. Worked well.

Bought this item for my outdoor boiler as soon as I opened water valve it was the first to leak.

The threads are metric. The description is 1/2" imperial. My system is imperial. I didn't attempt to use it for a couple of weeks after purchasing so hopefully it can be returned to Amazon.
