“Let me first say, I'm not a plumber. Nor do I have any clue what this device does. What I did know was my old one leaked, and this one does not. It's a magnificent device! Easy to replace and fun to throw away the old one.”
“I like this automatic air vent. It's very easy to switch to the off position when needing a clean. Seems to work much better than the other automatic air valves it replaced. Placed it on the boiler, and it went to work right away. The previous one wasn’t as effective.”
