Taco 400-4 1/8-Inch-NPT Float Air Hy-Vent

Works as expected and price beats local plumbing outlets

Works a designed

The first one they sent me was the version thats two generations old, with a more complex mechanism inside that has reliability problems. Even though I installed it carefully and bought the pressure (12psi) up very gradually by pumping up the expansion tank with a bike pump, it leaked water out the vent hole continuously. The vendor (Standard Plumbing Supply) replaced it with the latest version at no charge, no questions asked. Gotta love em.

easy to replace

Great Amazoner Thank You A++++

I shut the system down, ordered this part, it came in the next day, I installed it. It does what its supposed to, end of story.

It works like it should.

I liked the product fine. It is heavily built and performs the job .I cant know about unit function until heating season but, for now it is perfect.

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.

worked as advertised
