Review on Efficient Water Management With Beduan Brass 10500-VE Automatic Float Valve And Air Release Valve by Jose Pacyga

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.
