“I've used several kinds of air vent in hydronic heating systems. Most don't pass the test of time , they get corroded or scaled up and either leak or won't vent but these guys keep working for years and years. These are the only kind I'll use.”
“Very easy to install, just hand-tighten with some Teflon paste. The vent works well and releases air without leakage when done properly. Following the correct procedure ensures a long-lasting, efficient operation.”
“Very high quality. Easy to install. Huge difference comparing to the old fashion air vents. My appliance is very low pressure (12 psi - water-based home heating system), and air vents often do not work, but this one does the job perfectly.”
“I installed the vent in a low pressure in-floor heating system that has never been without air problems, including leaky vents.. This vent was perfect from the beginning and has been over the winter. When releasing the small air bubble, there is never a water leak. Excellent value for the money.”
